problems simulations
 
Hi, I am beginning to use the program Star-Ccm+ for the thesis, and I have some problems.
I must simulate I exchange him/it thermal a door injector, but I have some problems.

- I wanted to use a mesh "trimmed" but I don't succeed to d to apply her/it to more regions, as I can do.

- Doing use a mesh polyhedral the simulations they don't converge, do the residues of tke and tdr climb over 100 particularly, from thing you/he/she can depend?

thanks thousand

If you want to use a trimmed mesh then you can select the "Per region meshing" option on the mesh continuum.

Sometimes this is normal, look at your initial conditions.
How do you calulate? Steady or unsteady?

you may also want to try activating the 'Cell Quality Remediation'. This works well if the turbulence equations do not seem to converge.
