Dear developer,
I am trying to do one case with different meshes. I created three meshes for one model. There were 1,502,817; 485,288 and 707,893 elements. I use the same boundary condition. However, only 1,502,817 finished the simulation. 485,288 showed NAN at 581 step and 707,893 showed NAN at 1100 step.
I wonder is there a problem with the mesh?
Thank you very much.
Have a nice day. -V-
Yours,
Dai
Simulation shows NAN

Re: Simulation shows NAN
Hello Dai,
What solver are you using and what OS are you running on?
There might be a problem with your mesh although I think that you would get bad results right away. Try to reduce your time step and see if that helps.
Cheers,
Dave
