Author Topic: Numerical instability immediately after resuming, after a graceful STOP  (Read 341 times)

A run was 211s into a 600s simulation when I wanted to STOP and resume the next day.

I clicked STOP in the Pyrosim Run dialog until it replied with "STOPPED by user...."

The next day I Resumed the run using the Analysis menu and straightaway the run stopped due to Numerical Instability.

Being suspicious, I saved the file with a new name and started the run from the start.

It has gone past the point where it was "Numerically Unstable" and is now showing at t=326, 1.5s per 100 time steps in the log entry (ie looking good to finish without instability).

Can anyone offer an explanation?
