Hello All
First thread on the forum! I am attempting to model a large (68000m2) lagoon in simplefoam with a single inlet and outlet. The purpose of this is to use the steady state velocity as a start point for a tracer solver to determine the residence time in the lagoon. I've sucessfully used simplefoam and the tracer solver before on smaller situations but I'm getting stuck early on with this one. After sucessfully meshing the lagoon, I run the simplefoam solver and immediatly get a floating point error at time 0 for phi. Quote:

Hello Nima
Thanks for the offer - I managed to solve it. By rebuilding the entire model from scratch the problem went away. I think what caused this error was something in the mesh to do with local coordinates - I had for the first time tried to alter them, then decided not to (in salome). Not touching them at all as I did the second build avoided whatever happened! |
