Once the structures are modeled in RFEM, the form-finding process can be initiated. In RFEM 6, this is done by assigning a load of the form-finding type to elements, such as membranes and cables.
Depending on whether you have activated the Standards for Combination wizard and classification , it is necessary to specify a special action category for the load case.
There is also an extra tab for the add-on in the static analysis settings in RFEM 6. The details can be found in Chapter Static Analysis Settings - Form-Finding Tab of this manual.
