openfoam-dev wave tutorial

lsb1292 · October 14, 2017, 01:21

Hello folks,

I'm working on wave tutorial.

I want to change water free surface level.

The free surface level seems to be decided at topoSet step.

But I don't exactly understand the usage of topoSet especially box (xmin,ymin,zmin) (xmax,ymax,zmax).

And I also don't understand the difference between zeroGradient and fixedValue.

Can anyone explain these questions?

thanks!

topoSet creates a set of cells which is used later on in the refineMesh dict. topoSet does not create the free surface level. The free surface level can be changed in blockMeshDict file.
