Re: Convergence, windtunnel with obstacle
Hello, The problem that you want to simulate is a 3D problem and you are solving a "2D" (only 1 cell in the z-axis), this will change the flow around the cube. Additionally, the paper mention that the copper cube is cover with a epoxy layer of 1.5 mm and at its interior surface, a constant...

Re: Mesh version problem
Hello,
I'm not sure..but I think that when you export the mesh in CGNS the names of the face groups are changed. So, you can do first a mesh preprocessing in order to identify the new group names in the preprocessing.log file and then update the names in the BC definition.

Luciano

Hello,
The file that you have to read in order to load the BC's is the preprocessor.log as the pop-up notifications says.

Re: Crank-Nicolson
Hello, The option to change the time stepping scheme is "ischtp", the doxygen doc says that ischtp=1 is 1st order (default) and ischtp=2: 2nd order. I think that you can set it using the subroutine usipsu in the cs_user_parameters.f90 by setting ischtp=2. Also, if ischtp=2 the code set the...

Hello,
In CS 5 you have to switch to the "prepocessing mode" (in the fig that you post you are in the "calculation mode") and then select "mesh quality criteria" in the preprocessing type.

Re: How to plot residuals in Windows?
Hello, From yours xml files I saw that you are running 16000 iterations using a variable time step in space and in time with CFD=1 and Fo=10, so if you refine the mesh the, solution that you are showing in the last two figures doesn't correspond to the same "instant", because you change th...

Re: Number of processors
Hello,
In Section 6.5 of the install guide you can get additional information about MPI. Also, you can check and post the config.log in order to get detailed information about the error message.
Did you try to run a parallel helloworld?
