I have convergence problems and/or unphysical temperature peaks when using the CHT model in CFX-5.7. What can I do?
The recommendation is to change the diffusion scheme used with the CHT model. To do this you need to use the expert parameter '"cht diffusion scheme". A more robust but less accurate scheme (positive definite) is used if the parameter is set to: EXPERT PARAMETERS : cht diffusion scheme = 3 END |
