Good luck, by the way - your reply is off-topic as this thread is about surface triangulation for snappyHexMesh

Thank you for your reply.


I am starting a new thread.



So, if I want to handle this non-orthogonality in heatTransfer problem, where I am using chtMultiRegionSimpleFoam, which laplacian scheme should I exactly use?
Code:
laplacianSchemes
{
    default         none;
    laplacian(alpha,h)  Gauss linear corrected;
}
Should I change laplacian(alpha,h)? Which scheme should I exactly use? I am sorry if iI am asking stupid questions Because I am not very familiar with numerical schemes.


Also, should I change this laplacian scheme in all the regions of my case or just the fluid region?


Thanks.
