Is it possible to calculate stress in matlab using M,K matrix from ANSYS?
Hello,
Is it possible to calculate stress similar to ANSYS using stiffness, mass matrix, and mesh data exported from ANSYS in MATLAB? I have successfully obtained the final deformation using the HHT-alpha method, which is ANSYS’s transient analysis algorithm with M and K matrix. Although there is a slight difference in values, I believe it’s due to the error in calculating the inverse matrix. Now, I want to calculate the stress using the deformation but I’m having difficulty grasping which method to apply. Is it possible to write code entirely on my own without using the PDE toolbox to achieve stress values similar to ANSYS?
I would greatly appreciate it if you could provide me with any related code, materials, or detail methods.Hello,

How to use a spline for double values of y?

Missing faces in .step files for flexibleBodyModelBuilder
Hi,
I’m encountering issues with several geometries that I’m working with in the flexibleBodyModelBuilder tool for Matlab. In the 3D viewer of the tool, some faces aren’t represented, and there’s no explanation, leading to meshing errors and the ROM file not being generated as the body has become hollow. They work fine within Inventor (where they were modeled) and import without issues into other applications such as Ansys Discovery. Are there any workarounds to this issue?
Much obliged,

All ADF dataflow stages disappear after publish
Hello,
I made a source for my Dataflow and added several stages to the existing one. I published Dataflow and got publish succes. After run pipeline showed an error ina new source in dataflow. I tried to delete it (new source), but could not delete it. I succes published again and all my stages disappeared.
It is not possible to publish data flow like a this, because I will get an error, because there is no connected sink. In any case, it should have been publish with all steps.
How to get them back, why did they disappear and what happened?
And so it was before that. (It’s from last pipeline monitoring)

SharePoint Access Request Email Form Error
All users are receiving the following error when clicking Approve or Decline in the email form for SharePoint access requests: Could not complete the requested action. Please try again later.
These users have the appropriate permissions as the workaround to navigate to the SharePoint Online access request page and Approve/Decline works without issue. The error is only occurring in Outlook (desktop client and web client).
I’ve attached a couple screenshots. The error pops up whether you select Edit or View, and whether you click Approve or Decline.
I do have a ticket open with Microsoft, but it’s been open for a week and no resolution yet, so I’m hoping to find someone else who’s seen this and solved it.

Implementation of Facenet in Matlab
I’m trying to implement a system that’s identifying faces in real-time – both of known (trained upon) individuals, and unknown persons. In addition, it should put a bounding box around them, with its accuracy score – similar to Facenet. Is there an example of this in Matlab ?
By identifying the known and unknown individuals, we aim at providing the total head-count in a given frame.
I am trying to then later use Matlab coder, to transfer this program to my Nvidia Jetson Platform, so DL models are preferable.I’m trying to implement a system that’s identifying faces in real-time – both of known (trained upon) individuals, and unknown persons.

What is the Maximum Transfer Limit on PayPal?
Technically, there is no limit on your maximum transfer amount if you have a verified PayPal account at +1(801)512-0224. But generally, the maximum transfer limit for a single transaction is $60,000. If you don’t have a PayPal account, you can send a one-time payment of up to $4,000 USD.
What is the PayPal Transfer Limit Per Day?
The maximum amount that can be transferred in a single day is $100,000. But sometimes, the maximum transfer limit on PayPal varies depending on the user’s account type, location, PayPal balance, and history.
If you haven’t verified your PayPal account, there’s a limit on the total amount of money you can send. There is also a $500 maximum limit for withdrawals from an unverified account. Additional PayPal fees may apply.
Bank Account Transfer Limits
PayPal’s instant transfer limit for banks is a daily maximum of $25,000 and is $10,000 per transaction. This is significantly higher than the maximum sending limit if you connect through a debit card because your identity is already verified.
Debit Card Transfer Limits
When connecting with a debit card, there is a minimum transfer amount of $1.00 per transaction. The maximum limits for debit card payments are as follows:
$5,000 maximum per transaction
$5,000 maximum per day and week
$15,000 maximum per month
Lifting PayPal Transfer Limits
PayPal works better when you trust them. The best way to get around strict transfer limits is to become a verified user of the online payment platform. When you provide more information about your identity, it eliminates security risks.
Once your account is verified, a business can send up to $60,000 per transaction. There are also no limits on how much you can send from your PayPal account overall. Since your financial institution is now connected, the transactions become more like a bank transfer or a wire transfer.
Freelancers and small business owners should be the first to verify their accounts. Having a higher maximum limit enables you to use PayPal as a more reliable payment method. You can also accept payments more quickly with a verified account.
