Display water surface with water depth colouring

Hi everyone

Context:
I’m working with the BASEMENT model (www.basement.ethz.ch) to simulate environmental fluid flow.

What I have:
What I’m getting as output is an .xdmf file containing a) water depth information and b) water surface elevation information of the computational mesh.

What I need:
My goal is to visualize the 3D water surface / water level (using water surface elevation information) but with the colouring defined by the water depth.

Currently I’m only able to visualize either the water surface (but it doesn’t show the actual water level, it shows water surface projected on the grid) or water depth. Basically, in my example the sink should be completely filled and the water depth should be displayed in colour. How would this be possible?

Data: output_run_a.xdmf

Any help is much appreciated, I’d be really glad if I could solve this!

Thank you very much and have a good day everyone

Is the following procedure what you are looking for?

  1. Cell Data to Point Data filter
  2. Warp By Scalar filter
  3. Select warp_surface for Scalars in the Warp By Scalar filter
  4. Coloring with warp_depth

This is exactly what I was looking for! Thank you so much I’m very grateful.

I actually found that in step 3 I need to choose water_depth as warping scalar (instead of water_surface) as this will add the water_depth on top of the base elevation, so will properly represent the surface of the water.

Thanks again!!
