Hi Yvan, Many thanks for the quick response. I defined a post-processing mesh to view the selected faces and to me it looks like the code is not able to select any faces that lie on the xz boundary faces of the channel domain (which are joined for periodicity before the mesh insertion function is ca...

Hi, I am using ver 7.1.1. My domain is a rectangular channel. I want to insert a circular patch of cells as boundary faces on each of the spanwise faces of the domain and I have included this function in cs_user_mesh-boundary.c void cs_user_mesh_boundary(cs_mesh_t *mesh) { { cs_lnum_t n_selected_fac...

Hi I'm looking to run a frozen turbulence RANS simulation. Once the turbulence field is initialised at the start of the simulation I wanted to switch off the update of the turbulence quantities for the subsquent time steps. The iccvfg=1 option turns off the update of the momentum equation as well bu...

Hi I am using v7.1.1 and trying to output profiles based on the example provided, however, the profiles directory is created but no files are written in there during runtime. my domain is a rectangular channel of 0<x<22, 0<y<2, 0<z<0.06 and I want to create y-axis profiles at various x locations. In...

Hi, I'm using the Launder-Sharma low Re model, and I had a query regarding the exact expression for turbulence dissipation that is being used in the model and its BC at solid wall. There is the classical definition of turbulence dissipation: epsilon and a modified expression varepsilon (defined usin...
