We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

My apologies, the linear periodic is only supported in one direction. Refer to post:

/forum/forums/topic/linear-periodic-bcs-in-both-x-and-z-directions-causing-meshing-error/

You can try using a frictionless support on the boundaries of the other direction. This sets up essentially the same constraints as a mirror condition in a structural analysis. A mirror condition is not the same as linear periodic but it may suffice depending on the loading.
