waves, forces and the pressure field with OpenFoam 1.6-ext

maxonline · April 2, 2013, 06:10

Hello everyone,

I am currently working with OpenFoam 1.6-ext to generate waves using the toolbox waves2Foam. Everything works just fine.
Now I want to calculate the forces acting on a monopile due to the wave loads by using the the function "forces" (libforces.so). Therefore I need to define a pressure field "pName" but OpenFoam just calculates pd which is just a mathematical value, I guess?!
So is there a way to get OpenFoam to calculate p (total pressure) and also rho?

Thanks,
Max

are you find out forces on your monopile
i stuck here, can you help me
