help: an error occurred in the process of simulation
 

An error occurred. The simulation stops. i do not konw how to solve it.

This is a segmentation fault and likely a bug. Report this to your support engineer.

What were you trying to do?

I just try to compute a drag of the structure.

I remeshed, run the simulation again. After a while, simulation stops.

So at some iteration N it just stops and gives this message? Something has to have changed.

yes, the simulation just stops after some iteration N. in low fr number, i change the time step, turn time step smaller, it works. but in high fr number, i also change the time step, it does not work.

Are you running this with a custom Java macro?

No,I do not run this with a custom java macro.are there some physical variables such as p,v,k,w divergency？Because of divergency the simulation stops after some iterations.
