Hello,

I am trying to implement boundary conditions for a complex fluid in a deforming mesh (using pimpleFoam). Due to the complex fluid, I have two additional scalar fields (components of a tensor in 2d) aswell as a scalar tracer field in my simulation. How can I best implement the boundary conditions, such that I can set the components of the tensor for example parallel/normal to the moving (!) boundary, similar to a movingWallVelocity condition, just for the scalar field?

Thank you so much for every info you can get me!
