Hi
I found that the pressure term in the momentum equation in icoFoam does not divided by the denssity rho. Isn't it magnified the speed U by rho times in this way? Any one who could tell the reason? Thanks. |

Dear Yu
If you open the p in icoFoam/cavity/0/p you can see that: Code:
dimensions [0 2 -2 0 0 0 0]; but it differs for compressible solvers for example if you see the tutorials/compressible/rhoPimpleFoam/ras/cavity/0/p you can see that: Code:
dimensions [1 -1 -2 0 0 0 0]; So in conclusion,p differs in compressible & incompressible solvers. Good Luck
