Simulation of scrubber using simpleFOAM
 

Hello friends

I am trying simulation single phase scrubber using simpleFOAM. I did geometry and

meshing using gambit. During the solving I found the error of sigFPE

can you help me for that

Hello Harsha,

can you post your case ?!

scruuber_case
 

I'm not able to attach mesh file because it's file size exceeds

upload it in dropbox

I have upload it in drop box

Check your mesh, it seems the solver failed due to failure in mesh.

Check mesh quality by running the following command (in terminal):
checkMesh

Try correcting skewed cells

Best Luck!
