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?

No, the file needed is the "listing", attach this file.

Hello,

As the message says, "Check Code_Saturne log (listing) and error* files for details". Check the listing file in the RESU directory in order to have more details about the error.

Hello, I think that you forget to specify the velocity direction at inlet BC, maybe this is the problem. Always search in the forum your keywords ("lift, drag, etc") in order to know if someone has ask the same question, I leave here a link http://code-saturne.org/forum/viewtopic.php?f=2&a...

Hello,

In section 5.4 of the theory guide and in section 8.2.5 of the user guide (Ver 4.3) you have information about the wall functions and the turbulence models. I think that should change your turbulence model to K-omega or V2-f.

Hello, Yes, N_iter are number of iterations used to solve the linear system to the relative precision (epsilo). You have a section in the user guide (8.2.11) about error estimators for Navier-Stokes. If the derive has dropped several order of magnitudes this means that the flow is not changing and y...

Hello,

In the listing file you can check the mass flow conservation in the section "BOUNDARY MASS FLOW INFORMATION"; there you have for each boundary condition type the mass flow and I think with a value of 0.58E+12 your solution it is not converging...

Hello, Yes, if you want to read in Paravis you have to save in csv format and about how many points, this will depend of your physical problem, the domain, etc. You have to know where to locate them. The lines of code that I posted are not exclusive for CS so you don't have to implement anything, yo...

Hello, As Yvan mention, you could use monitoring (probe) points inserted through the GUI (Calculation Control -> Output control -> monitoring points) in different spatial location in order to check the time/iteration evolution of your variables (pressure, velocity, etc), but not the derive indicator...

Hello, I was reading your last listing file and note the following things. Issue has been detected during the mesh quality check, also you have a message that all your cells have a mass source term, it is correct? At the outlet you are using a free inlet/outlet BC without a external head loss defini...
