grid movement - incompressible regime

suman91 · February 24, 2015, 15:16

Hi, I was trying to run the NACA 0012 plunging test case that was there by default in the Test-case master folder. I just changed the regime to "INCOMPRESSIBLE" and changed the free stream definition also by giving - density, velocity and viscosity as input. I am getting a "SEGMENTATION FAULT". Is the grid movement not there for incompressible regime? If not can someone tell me where in the source code I need to make changes. I know there is a ROE-TURKEL Pre-conditioning that will allow me to run low mach
number problems using a compressible solver, but I want to use the
incompressible regime only.

Will be looking forward for a reply. Thanks.

The ALE formulation has not been implemented in the incompressible solver. It is not a terrible task (you just need to mimic the compressible implementation) but it requires some work. Please let us now if you are interested in implementing that capability and create a push request in GitHub.

Hi,

is this information still up to date for Version 4.3.0? Or is it planned to be implemented in future releases?

Best regards
