Transformin Lagrangian data to Eulerian ones
I'm trying to apply the effect of bubbles on propagation of waves in liquids. I have already modeled the motion of bubbles in a Lagrangian frame. However, to apply their effect on the wave (which is a field quantity, i.e. pressure field), I need to change the data from lagrangian approach to an eulerian one. Better to say, by knowing the position and diameter of the bubbles from a particle tracking method, I want to find their volume fraction as a field variable. Has anybody experience about this problem. I use the injectorParticleFoam with some modifications which are working properly up to now!
Thanks a lot in advance and best wishes,
