When running simpleFoam i am getting a floating point exception (core dummped message)

Floating point exception (core dumped)

I cant figure out where i am going wrong. When running check mesh i also get one failure but cant figure out where it is.


I have attached all the files i am using for the problem in the this mod_8 zip. and also attached the files i think are needed for use.
i deleted the polymesh so blockMesh will need to be run.

Hi,
From lines #3 and #5 it seems that the simulation stopped due to the GAMG solver. Try using smoother DICGaussSiedel instead of gaussSiedel for p in fvSolution.
If it doesn't work, try with PCG solver instead of GAMG, and preconditioner DIC. Let me know if something changes.
Regards,
Lorenzo

Lorenzo,
I did as you said for both cases the first one did not solve either, only doing two time iterations. I will include the error message i receive here: (GAMG, DICGaussSiedel)

for the PCG and DIC it ran for about 5 time iterations and then stopped. below is the core cumped message:
