Hello,

I'm trying to create a slit made by several laser lines in a block. The block is significantly bigger thant the slit. The slit has a weird shape due to these laser lines. I want to add a predescribed displacement on the vertical surface of the long edge in the direction of the outside of the block. The attached model is how I want to model it only I get a bunch of errors.

I get these two errors after computing:

Failed to evaluate operator:
- Operator:mean
- Geometry: 1
- Boundary: 67,69, 70

Failed to evaluate expression:
- Expression: mod1.solid.disp
- Plot: surf1(Surface)

and

The following feature as encountered a problem:
- Feature: Stationary Solver1 (sol1/s1)
- Error: Failed to find a solution

How can I make this model work?

Thanks a lot in advance
