Restart functionality and simulation divergence
Hello everybody,
I'm using mbdyn coupling it with CFD and with the CFD case size increasing I'm having trouble to finish the simulation due to time constraint in the cluster. So, the restart functionality is important for me to continue the simulation.
From what I understood, reading the manual and the codes, there is the functionality of writing a file to restart the simulation, but doing tests, this file ended up generating numbers, in the element part of the file, like 1.996025e-320 that led to an MathParser
error. Replacing these numbers type by zero solved the error, but the simulations did not converge after the restart and the residuals are much higher when compared to the case without the restart for the same timestep.
Well I would like to know if anyone is working on this problem or if not, I would like to help make this functionality work at least in principle for the beam structural part of the program. Any idea or hint what might be missing in the code so that this divergence does not occur in the continuity of the simulation?
Thanks!
