Directed meshes from Star-CCM+ not working properly
Posted: Thu Dec 14, 2023 7:00 pm
Hi all,
I am currently trying to use Star-CCM+ to generate some coarse meshes to use in Code_Saturne. Usually in Star-CCM+ you would use the Automated Mesh option with different parameters to automatically generate the mesh that you want, but I need to use the Directed Mesh option as I need to (semi) manually generated a customised mesh pattern for my geometry.
I have successfully run simulations using automated meshes from Star-CCM+ imported into Code_Saturne before, using the CGNS format. However, as for directed meshes, I can successfully import the meshes to be read in Code_Saturne, but the boundary conditions that I specify (in the GUI) don't seem to be working - I specified an inlet velocity but the entire fluid domain remains static. I've followed the same procedure for both an automated and directed mesh for the same geometry but that the simulation works with the automated one and not the directed one. Not entirely sure what's going so I figured I'd just ask here, if there's anyone that's familiar with Star-CCM+ meshing that might be helpful too.
I've attached the two mesh files of a simple cubic fluid domain, one automated and one directed, as well as the .xml file of the Code_Saturne simulation.
