Frequency domain solver
I wonder if it is possible to create an OpenFoam solver able to solve a wave propagation equation (for example Helmholtz wave equation) in frequency domain.
I know the potentialWaveFoam solver is able to solve the wave equation in time domain. But I'm only interested in stationnary wave problems and maybe someone knows if it's possible to change OpenFoam from time to frequency domain...:confused:
I ended up using the Helmholtz solver from Elmer instead of OpenFOAM.
Thanks jdv for this reply.
I was not aware about this lack dealing with complex fields. The major issue I encounter with OpenFoam is when I want to use cfd results (pre-computed flow fields with icoFoam for instance) as inputs for acoustic computation (a kind of Direct Numerical Simulation of Navier-Stokes-Fourier equations).
Maybe someone knows if it is easy to handle this kind of process within OpenFoam ?
For the question of time to frequency domain, I chose to make a time domain simulation and compute the DFT as post-processing step.
