Hello Everyone,


I am currently working on a VAWT project, so far I have created a two bladed design by Pointwise and exported the files, I have managed to do checkMesh and it is OK. however, I could not run PimpleDyMFoam where errors message of Floating point exception (core dumped) occur as bellow,

please could you let me know whats the problem here?


Have a good day!

Hello.
For now your Counrat Number is little too high. Try to decrease timestep to get max Cournat number close to 1-2.

Hello Sheaker,












Thanks for your reply, I have induced the timestep for the Counrat value and made the maximum range around 1.6. However, still the same error is occuring and baring in mind that my mesh is ok. Could you have any other suggestions about the issue cause?










Have a great day

Hello Sheaker,








please could you check the attached file of '0' and 'system' to check if there are any issues ?











Thanks
