prism layers at free surface.
 

I need to refine mesh at the free surface interface between water and air. Any idea how to refine mesh at free surface. Thanks

Re: prism layers at free surface.
 

Just define 2 regions and enable the "grow from interface" option.

Thanks Balduin Bankerotti!!!

Could you please give a hint, how to define two regions. Thanks again :)

Check the "Heat Exchanger Unit Meshing Tutorial" tutorial.

Why do you want prism layers at the free surface? There isn't much point in splitting the domain in two and then re-meshing, it is just making more work for yourself, why not just use a mesh volume source and refine within it?

Use volume sources where you have free surface to refine your mesh..

Thanks Bob!!! Is there any tutorial about mesh volume source
