Automatic code combinations can only be generated for linear static analysis as they are based on results of the previously calculated simple load cases. For non linear analysis you have two options:

 

1. Before you change the analysis type to non linear (or define tension only elements) you should generate automatic code combinations and then convert them into manual combinations. The option is available from the combination table as illustrated below:

2. Instead of generating automatic code combinations you can generate manual combinations in the automatic way. All you have to do is select manual combinations generation in the dialog shown below:

The DSC releases cannot be defined on bars with offsets as this produces incorrect results. In such case you have to switch the use of DSC off or replace offsets with e.g. rigid links or dummy bars.
