I am using pimpleDyMFoam to simulate a stirrer. The Courant number is within the specified limits and the residuals seem to be okay too. However the following error is obtained.
Code:

Hi Sorabh,
I am also encountering a similar floating point exception error and I suspect this is due to a failed mesh check. Apparently there are some concave cells in my mesh. Strangely, I did not encounter this error before using a similar mesh. Just wondering whether you had managed to solve this issue and, if so, how you did this? I am also using OpenFOAM 5.x. Any help will be appreciated. Thank you. |
