Issue with Contact analysis in Simscape – solid body contact
Hi,
I am trying to simulate a gear pair contact analysis in Simscape where I import the bodies from stl file. Upon simulation, the gear tooth meshings are not happening correctly and I have severe interference. I tried solving the issue with different solvers, but still the meshing is not appropriate. Could you please suggest how I can solve this issue?
Thanks,

How to fill missing time points from a txt file
I have txt files that I am trying to read in and towards the end of the file it starts skipping time values and data points. I am trying to compare this txt file to another excel data set. I would like to create the missing time variables on the txt file and just fill them with NaN variables that way I can better match up the time. Should I use the fillmissing function? Any suggestion would be appreciated.
The excel file is also time shifted by about 3 seconds late so that is another problem I will have to face.I have txt files that I am trying to read in and towards the end of the file it starts skipping time values and data points.

How to create a Simscape custom component with 2 different thermal liquids?
Dear all,
I am currently trying to create a custom component block for Simscape Thermal Liquid that models the heat transfer behaviour of a specific heat exchanger between two different thermal liquids. The code creates the block with no errors, nor warnings, and runs fine as long as I do not define thermal properties for both liquids. When I do define thermal properties for both liquids, I get the following error:
I imagine that the error comes from the fact that my code "expects" the 4 nodes (in/out for both liquids) to share properties, but I cannot find where that definition comes from…
Does anyone know how to define nodes that do not share fluid properties?
As a simpler test case, I am trying to make it work with a custom component block based on the Flow Rate Sensor (TL) library block, with 4 ports instead of 2. Same error comes up, but the code is much simpler to work with:
component flow_sensor_two_fluids
nodes
A = foundation.thermal_liquid.thermal_liquid; % A :left
B = foundation.thermal_liquid.thermal_liquid; % B :right
C = foundation.thermal_liquid.thermal_liquid; % C :left
D = foundation.thermal_liquid.thermal_liquid; % D :right
end
outputs
M1 = {0, ‘kg/s’};
M2 = {0, ‘kg/s’};
end
annotations
[M1] : Side=top
[M2] : Side=bottom
end
variables (Access = protected, ExternalAccess = none)
mdot1 = {0, ‘kg/s’}; % Mass flow rate from port A to port B
Phi1 = {0, ‘kW’ }; % Energy flow rate from port A to port B
mdot2 = {0, ‘kg/s’}; % Mass flow rate from port C to port D
Phi2 = {0, ‘kW’ }; % Energy flow rate from port C to port D
end
branches
mdot1 : A.mdot -> B.mdot;
Phi1 : A.Phi -> B.Phi;
mdot2 : C.mdot -> D.mdot;
Phi2 : C.Phi -> D.Phi;

M1 == mdot1;
A.p == B.p;
A.T == B.T;
M2 == mdot2;
C.p == D.p;
C.T == D.T;
end
end
Thank you for your help!

Blank page when I select Share Point list
Hi,
I have a Share Point site and it has 5 lists. I have worked on these lists for a few years and as of today, 4 of them open as usual but one opens with a blank white screen. The following is the steps I took before this problem occured;
Changed to Classic Experience as I thought this would help with another problem i was having.Went to the settings of the list and opened up one of the views and re-ordered the columns so that a lookup column appeared higher up the list.Selected OK.
Rather than go back to the list, a blank white screen appeared. I have tried clearing the browser cache, re-booting machine, refreshing page etc but nothing works. This list was displaying normally until I made the above changes. Any help appreciated.
Thanks

Usability is lacking
My school recently switched from Google to Microsoft and there are a lot of things I like about Outlook but there are also a lot of features or lack thereof that I am finding extremely frustrating. One thing that has been extremely frustrating is that when I look up how to do something I will find the instructions from Microsoft but the instructions are not effective. For example, I looked up how to find deleted events in Calendar and it says to click on the “Folders” tab at the top but there is no folders tab. Similarly, when I looked up how to view flagged items it gave the option of using the “Folders” tab again in Outlook email but there isn’t a folders tab. I was eventually able to figure out how to view the flagged items. I just wanted to share some of my frustrations in the hope that you will be able to make improvements on the usability or at least the instructions provided online regarding how to use features or access different things on you software.
Also, I still can’t figure out how to access deleted events in calendar and would like some assistance. And please, don’t tell me to click on the Folders tab.

Created a measure as below:
Its giving me the correct values at filter context and total as well as shown below:
My expected outcome of this measure should be:
total 0.17 should be in all rows of DBName-point id(filter context) and not their individual values(for ex: INSE-1000 should have 0.17 instead of 0.12)
In order to achieve that,i created a measure as below:
But then it gives 0.155 in all rows rather than 0.17
To elaborate with another example:
Please find the below sample data link:

Diagnostic information:{Version:17.01.2050.000,Environment:EUSPROD,DeploymentId:12712fb5-4d56-4278-a07a-c5fe4e727652,InstanceId:WebRole_IN_77,SID:7459fef8-f40f-479e-9eab-39db22358c82,CID:c643511b-7dc8-421e-9ae5-4d8908b5e239}Time:2024-07-29T19:46:02.9377098Z Read More
Properties are not applicable to connector of type ‘OnPremises’ with the current combination.
It has come to my attention that there are new limitations on Inbound on-premise connectors. Specifically, the following options are no longer available:
• RequireTls
• RestrictDomainsToCertificate
• RestrictDomainsToIpAddresses
This change appears to be quite recent, as I’m unable to find any discussions about it online. The impact is significant – I can neither create new Inbound on-premises scoped connectors nor modify existing ones within our tenant.
Upon investigation, I discovered that Microsoft updated their documentation just four days ago. The GitHub commit (https://github.com/MicrosoftDocs/office-docs-powershell/commit/8ca7602b857e07f8d760922af0c3ca98a107c22d) indicates that these flags are now exclusively for Partner type connectors.
This change seems counterintuitive, as it prevents the creation of new connectors using the Exchange GUI or PowerShell with the recommended “Authenticating sent email” settings. These settings typically involve verifying that the subject name on the server’s authentication certificate matches the specified domain.
I’ve attached screenshots demonstrating the inability to update existing connectors with these flags or add new ones with these settings.
Has anyone else encountered this issue or have any insights into these recent changes?

Azure Monitor Logs Next Evolution: Multi-tier logging
Today we’re announcing the public preview of Auxiliary Logs, a new inexpensive Azure Monitor plan for verbose logs used in compliance and security scenarios. Together with the recent public preview of Summary Rules and improved capabilities of Basic Logs, Azure Monitor Logs is evolving into a new multi-tier logging vision.
Most organizations have many different needs for logging. This is because not all logs are the same – some are very frequently accessed, some are needed for investigation when issues arise, and some are kept mostly for audit and compliance purposes. When we talk to customers, we often hear that they use multiple logging services or products side-by-side to serve their needs, and this is slowing them down. They need to deploy, maintain and learn several different technologies just to observe their services. Customers are also telling us that they need to log much more data than before, which is ballooning their logging cost.
Azure Monitor is focused on addressing these problems with a single solution that includes multiple logging plans that cover a broad variety of scenarios. With Azure Monitor Logs, customers have a one-stop shop for observability.
These log plans are:
Auxiliary Logs – Our new, inexpensive log plan that enables ingestion and management of verbose logs needed for auditing and compliance scenarios. These may be queried with KQL on an infrequent basis and used to generate summaries.
Basic Logs – Improved to support even richer troubleshooting and incident response with fast queries while saving costs. Now available with a longer retention period and the addition of KQL operators to aggregate and lookup.
Analytics Logs – This plan is designed for frequent, concurrent access and supports interactive usage by multiple users. This plan drives the features in Azure Monitor Insights and powers Microsoft Sentinel. It is designed to manage critical and frequently accessed logs optimized for dashboards, alerts, and business advanced queries.
For detailed capabilities comparison between the plans, see our documentation. For the pricing of these plans, see here.
All these logs can be retained for up to 12 years, while being accessible using Search Jobs, that can scan Petabytes of data to find specific records.
Since all these logs are in Azure Monitor, it means that they have the same KQL query language, API, query and admin experiences. Furthermore, we’re not only integrating these logs under one roof, but also are providing additional capabilities to ensure that logs function cohesively:
Summary Rules – Continuous aggregation of raw data into compact summaries that are easier to analyze and cheaper to retain
Ingestion transformations – Enable filtering, enriching, and splitting data between log plans during ingestion
Search Job – An orchestrated long-running query that can scan Petabytes of historical data to specific records into Analytics tables for further analysis
With this, it is easy to switch or mix-and-match between the different log plans. Customers can start with a table that is configured with the Analytics plan, then can check if Basic Logs works for them through a simple configuration change. If they find that they need more capabilities, they can revert to Analytics.
Here are two examples how these plans work together to create an improved solution:
Firewall logs can be huge, 100s of TB per day of highly verbose data. Firewalls are optimized to omit all communications details. While most consumers don’t need the raw data for day-to-day use, organizations do need to keep it for auditing. In Azure Monitor, customers can now send all firewall logs to Auxiliary Logs and retain them per compliance requirements. On this data, customers can run a summary rule that creates hourly aggregations. Investigators can use these aggregations for their day-to-day work and if they need to drill down, they can easily query the relevant records from Auxiliary Logs.
Some logs contain highly important information mixed with less important data. Customers can send these logs using our pipeline Data Collection Rules and split the data between Analytics and Basic Logs. The highly important records will have all analytics capabilities, while the less important information will be available for troubleshooting at a lower.
We are working closely with our customers to collect feedback and will continue to add more functionality to the service. We are always interested in hearing your thoughts and understanding how you apply Azure Monitor Logs to your environment. You can contact us using lafeedback@microsoft.com or via our feedback community forum.
