I would like to put a plate on a line support with spring stiffness varying linearly about the line support length. Is there any option in RFEM to model exactly this case?
Unfortunatelly, there is no option of defining a variable spring using the support length. In this case, you should set a nodal support in a sufficiently fine part and assign these different spring stiffnesses. If you set the nodal support on a line, it is always possible to imply a node. At the same time, the node also represents an FE imposed node, which means that an FE node is created on this node automatically.
