Why can I not use `solid.d` in the Symmetry node?

I have a Solid Mechanics plane strain physics problem, where I use a Symmetry node. If I use a Normal Direction Condition -> Prescribed force, I want to scale the result by the depth of the problem. So logically, I would want to sayFn = 1[MPa] * solid.d * height
or similar. However, then I get an error, "Undefined variable. - Variable: comp1.solid.d". If I usesolid.d
in other context (e.g., a Boundary Load or a Weak Contribution) it works fine.
Is this a bug or is there a subtlety of COMSOL I'm not getting?
