Hello CFD Enthusiasts

Currently I am playing around with a wedge shaped pressure source moving in an open channel with interest in determining the height of the wave created on the freesurface. I will not this simulation is for education and interest purposes.

I am a CFD beginner and I am having trouble setting up Fluent (17.0) to perform the simulations and would really appreciate some help!!

My setup is as follows:

Mesh of domain and pressure source model outline seen in mesh pngs

Pressure based transient solver gravity set -9.81 in Z
VOF and standard k-e models (all default values used)
Boundary conditions can be seen in BCs.PNG
I think the boundary conditions are my problem.

Phases are assigned by marking cells and then patching volume fractions to cells in solution initialisation.

All my results are going no where and I'm not sure what to do!

I get a message in the console saying my turbulent viscosity is limited.

I do have some (very few) elements that have a high skewness.

If anyone could offer some help in getting this to solve it would be very much appreciated.

Thanks CFD-Online community!
