Hello,

The error message should be self-explanatory.

As I recommended to you in another post, please read the short section of the installation manual relative to optional libraries. On Ubuntu, you can install MED using the package manager. Or you case use the one from SALOME. Or you can try doing your whole installation using the install_saturne.py automatic installer.

Thank you,
definitely will read through.

Is it the same for windows release? ie also prerequisites should be installed?

Hello,

No, the Windows version should contain everything you need. But it is still considered "beta status", as we have less feedback. You are welcome to try it.

Hello,

I tried Windows version once more time and problem is still the same: "Check mesh" works fine (mesh_input file generated with all groups) but cannot add anything from this file when defining boundary conditions (ie cannot import groups and references from Preprocessor listing).
Did anybody try to do that?
Any ideas how to solve it?

Thank you!

Hello,

Did you run a "check mesh step" or run the code in preprocessing mode first ? You need a preprocessor log to do this.

Thank you.

I make "check mesh" step first and get the following file:

what do you mean with "proprocessot log"?

Hello,

In the case of "check mesh", it might be called "check_mesh.log" or something similar (it is a concatenation of preprocessor and solver logs).

Hello,

shouldn`t be this log file automatically generated (like in GUI CS 3.0) after "check mesh" operation?
In current CS 4.0 windows release - just mesh_input file created, no any log files.

Hello,

could you please help me to solve the following fatal error:
MED does not allow to export an empty mesh,
Mesh: "InteriorJoinedFaces_j03" has no vertex.
Associated file: "postprocessing/joining.med".

geometry: https://www.dropbox.com/s/rb0cthwq11nnn ... l.png?dl=0
I am trying to make full transient simulation using CS 4.0 GUI.
Looks like the problem is because of face joining (wheel_outlet with hus_inlet), meshes of this two regions are the following: https://www.dropbox.com/s/zgktq42kmxgbs ... t.png?dl=0
check_mesh.log: https://www.dropbox.com/s/f09n0f9u2prw0 ... h.log?dl=0

Thank you in advance!

Hello,

This means that at the starting time, the joining surface is empty. Either your meshes do not match, your selection criteria is wrong, or your geometry is such that joining does not occur in all rotational positions.

Did you visualize the output of the "check mesh" stage ?

In the first cases, you need to check your mesh and setup. In the last case, use the EnSight format instead of MED for the default writer, to allow empty meshes.
