Dear Bastian, I think the problem is iteration 190: you see that k equation failed to solve, doing 1001 iterations (the default limit) with diverging residual. This is something that sometimes...

Dear Bastian, I think you have a different problem here: iteration 191 shows that solution for k and epsilon is alerady diverging so that the successive failing is not a big surprise to me. My...

Replies: 15 Problem using single precision in simpleFoam Views: 4,159 Posted By luca_g This was my solution Dear Bastian, it is definitely worth running single precision but with turbulence model it is likely that occasional underflow/overflow happens in single precision. This causes exception and...
