Re: Parallel solver settings on Windows machine

Just for clarity, the file is not missing, is in that path.
The environment variables are OK, all looks good
May be the underscore on the executable name or the dot in the "Elmer 8.2-Release" directory causing problems when reading the path?

Re: Help for a simple CFD test case (NAN when running solver))

Problem is I get an instant NaN when running the solver. By tweaking up viscosity (increasing) and introducing a relaxation of 0.5 I can get out of the Navier Stokes solver iterations, but when k-epsilon solver starts is a new insta-NaN. Maybe is only a bad choice of parameters and algorithm for sol...

Help for a simple CFD test case (NAN when running solver))

Hello, I'm desperately trying to run my first own test case: It's a pipe filled with water (actually I'm using the "cylinder_in_channel.iges" from the Elmer samples directory) with: - a no-slip boundary condition on side walls and the square obstacle (Boundary Condition 1) - no boundary conditions o...
