What are Necessary Boundary Constraints? and Visualizing Force Vectors

Two questions:
1. Are constraints necessary? I have a square frame in 3D space, and I want to pinch two opposite corners together. There doesn't seem to be a need for any boundaries to be 'constrained,' yet if I don't constrain anything I get the error that the "relative residual is greater than the relative tolerance". What is going on here?
2. Is there any way to visualize loads as vectors?

Maddy

Hello Maddy,
1/ See www.comsol.com/community/forums/general/thread/95201/
2/ There is a tool in pre-processing that can show symbols where constraints and loads are applied, but these symbols do not indicate the direction or magnitude of loads, only their presence: File > Preferences > Graphics and Plot Windows > Show Physics Symbols To show the direction and magnitude of loads, you can use the arrow plot post-processing tools.
Best,
Jeff
