Combination of Linear and Nonlinear Supports

In general, you should clearly define the degrees of freedom on an FE node. If a nonlinear line support and a linear nodal support are defined at the same location (node), the requirement mentioned above does not apply. RFEM displays a message that supported nodes lie on a supported line. This warning should not be ignored.

To achieve the right support reaction, you should define the node and line supports in a geometrically different location. To do this, you can copy and move the supported node a few centimeters downwards and connect the new and originally supported node with a coupling member. Now, you can move the nodal support to the new node.
