How do I activate form-finding of a membrane surface?


The form-finding with prestress can be activated in the General Data of the surface by using the "Edit Stiffness Parameters" button.

The "Form-Finding" tab is visible when you activate the RF-FORM-FINDING module (in the Model General Data) for surfaces that have one of the following stiffness types:

  1. Standard
  2. Orthotropic
  3. Membrane
  4. Membrane - Orthotropic

Generally, the program automatically activates form-finding with a default prestress for surfaces with the stiffness type 'Membrane' and 'Membrane - Orthotropic'.
