simpleFoam p field for interFoam p field
I need to use interFoam to solve a problem, but it blows up within few time steps, which I believe is because of poor initialization . Hence I used simpleFoam to obtain the velocity and pressure fields. Now I want use the pressure field of simpleFoam (with units m^2/S^2) to obtain the pressure field of interFoam (kg/m/s^2) which is nothing but the product of pressure and density. How do I obtain this in openfoam?
some hints :) you need to investigate yourself ;)
1) Are you familiar with funkySetFields ? its great tool to make non uniform field
2) as a little I know ,you can easily change the dimension in p file ,so you can apply this pressure to interFoam
3)if you want to use pSimple*rho as new in interFoam, you should modified your solver!
something like that
p = pSimple*rho;
Thanks nima and Bernhard for your quick thoughts. I will try option 2 of nima and foamCalc and post my experience.
