Comments

  1. There is no convection through a boundary face.
  2. With a collocated scheme (/MAT/LAW151 (MULTIFLUID)) there is by default a slipping wall boundary condition ( υ n n = υ w a l l n MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqipu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=x fr=xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaeqyXdu3aaS baaSqaaiaad6gaaeqaaOGaeyyXICTaaCOBaiabg2da9iabew8a1naa BaaaleaacaWG3bGaamyyaiaadYgacaWGSbaabeaakiabgwSixlaah6 gaaaa@460F@ ).
  3. With a staggered scheme (all material laws, except /MAT/LAW151) velocity must be fixed with /BCS option at boundary nodes. You can define either a solid wall boundary condition ( υ f = υ w a l l MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqipu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=x fr=xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaeqyXdu3aaS baaSqaaiaadAgaaeqaaOGaeyypa0JaeqyXdu3aaSbaaSqaaiaadEha caWGHbGaamiBaiaadYgaaeqaaaaa@3F7B@ ) or a slipping wall boundary condition ( υ f n = υ w a l l n MathType@MTEF@5@5@+= feaagKart1ev2aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr 4rNCHbGeaGqipu0Je9sqqrpepC0xbbL8F4rqqrFfpeea0xe9Lq=Jc9 vqaqpepm0xbba9pwe9Q8fs0=yqaqpepae9pg0FirpepeKkFr0xfr=x fr=xb9adbaqaaeGaciGaaiaabeqaamaabaabaaGcbaGaeqyXdu3aaS baaSqaaiaadAgaaeqaaOGaeyyXICTaaCOBaiabg2da9iabew8a1naa BaaaleaacaWG3bGaamyyaiaadYgacaWGSbaabeaakiabgwSixlaah6 gaaaa@4607@ ).
