Do you mean to run an incompressible solution and then change to a compressible model and run a restart?

Re: Help needed for Windows build

You are right I was a bit tired while writing the post and supposed I was in the installation section of the forum.

I'll move the post to installation if it can help.

Compressible module "negative value of internal energy" error

I tried to run a compressible calculation on version 7.04 downloaded from the web site and installed on an ubuntu WSL2. I would simulate pressure wave propagation away from the explosion source. I expect to have low mach number but need to take into account compressibility and chose the compressible...

Re: PROBLEM IN THE BOUNDARY CONDITIONS USING COMPRESSABLE MODEL

I overcome the previous errror checking the "hydrostatic equilibrium at wall" box. But now I got the following error: Error in thermodynamics computations for compressible flows : Negative values of the internal energy were encountered in 1 cells. Call stack: 1: 0x7fed4f7d9dc5 <cs_cf_check...

Negative total energy value using compressible model

I tried to run a compressible calculation on version 7.04 downloaded from the web site installed on a ubuntu WSL2. I cant upload the mesh, too data.

Re: Help needed for Windows build

I resort to the semi-automatic installation and it works fine. I summarize my step: after the installation of the ubuntu WSL2 on a windows 11 using apt-get I installed a program that uses a GUI (i.e. gedit) to install all the necessary library set up in the home user directory the installation manua...

Re: Help needed for Windows build

Hello
under the WSL2 and ubuntu it is possible to install the version 6.0.2-1 available as a package in the ubuntu repository.
The GUI work out-of-the box with no need for a swparate xserver.

P.S. The version does not have the bug-fix for the compressible Module.
