Default compressible flow
Posts: n/a
Hi everbody!

I want to update my SIMPLE code for compressible flow, it works-more or less, a few questions: -what's better: to use a equation for static enthalpy or fore total enthaly or energy. I am using a. e. for static enthalpy and it converges very slowly.... -I get very often problems with my central coefficients for pressure correction, they get too small and diverges, any cure?!?! -what's about non-reflecting boundaries, always necessary?!?

Thank's a lot!
