Hi
I am trying to simulate a thermal fluid system. As soon as I introduce gas-charged accumulator circled red in the circuit, it gives me following error
An error occurred while running the simulation and the simulation was terminated
Caused by:
Derivative of state ‘pumpandpipe13082024b.Gas_Charged_Accumulator_TL.T_I’ in block ‘pumpandpipe13082024b/Gas-Charged Accumulator (TL)’ at time 20.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

Also, when I introduce elevation gain from port A to port B in pipes TL circled red, i have the following error
An error occurred while running the simulation and the simulation was terminated
Caused by:
Derivative of state ‘pumpandpipe13082024b.Centrifugal_Pump_TL1.A.T’ in block ‘pumpandpipe13082024b/Centrifugal Pump (TL)1’ at time 16.666666666666668 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)
what do these errors mean?Hi
