Implementing Direction-Dependent Etching Velocity in COMSOL Deformed Geometry

Hi everyone,
I am trying to reproduce the chemical etching tutorial from COMSOL (link: https://www.comsol.com/model/chemical-etching-44481 ). In the tutorial, they used Prescribed Normal Mesh Velocity in Deformed Geometry to describe the etching velocity, where the velocity value is constant. In my case, I would like to define a non-uniform etching velocity, meaning that the velocity in the x-direction is different from the velocity in the y-direction. I tried some approaches, but they didn’t work. Could you please give me some suggestions on how to implement this?
Thank you so much!
