Integrating Objects in Quadrangle Surfaces Automatically

Tips & Tricks

In RFEM, surfaces are automatically connected if they have common boundary lines. If the definition line of a surface is lying in another surface, the line is automatically integrated into the surface, provided that the surface is plane. For quadrangle surfaces, however, the automatic object detection is complex. Therefore, this automatic function is blocked. The integrated objects must be specified manually.

Luckily, RFEM offers an option that makes the integration of objects in quadrangle surfaces easier: By using the [Integrate All Objects] button, RFEM determines all nodes, lines, and openings that due to their geometry are relevant for integration. Then they appear in the list of the integrated objects, which can quickly be checked.
