Description: Finds shell elements whose material orientation angle (the THETA / Material Angle field on the element record) is missing or invalid, and adds them to a new flagged group. Useful for catching meshing oversights on composite parts where every element should have a defined fiber direction.

Use Instructions: Run the tool. Pick the elements to audit (default: all). Confirm. Flagged elements go into a new group named "Missing Material Angle" for visual review.

Requirements: Open FEMAP model with shell elements (typically composite / orthotropic).
