The direction of the flow field is controlled by setting varying divergence on the surface geometry.
The velocity field is computed via pressure projection and flows away from high divergence areas to low divergence areas.
Use OpenCL to run the pressure solve.
The voxel size to use for the velocity volume.
The width of the outer region around the surface to generate velocities for. This also has an influence on the field generated inside the geometry.
Pressure Solve Iterations
Number of iterations to run the pressure solve for.
