Creating 2D curvilinear coordinate system

Hi,
For my model I wish to add a curvilinear coordinate system on the middle layer of my model. Such that I'm able to define the anisotropic material properties along the curvature of the middle layer (sinusoidal layer). However, I keep receiving the message: 'Division by zero. - Function: / Failed to evaluate variable. - Variable: comp1.cc.vX'
I'm don't what's wrong with my model, since I followed the same steps as the provided 'carbon fiber' tutorial on curvilinear systems in the application library. Does anyone know how to fix the model?

A first guess would be that you try to solve for the orientations of the coordinate system in the same study (or study step) as the physics that is going to use these orientations.
