MIDAS Cannot calculate Stiffness of composite section


I was unable to proceed with Adding Composite Section for Construction Stage.
Error appeared with message "Cannot calculate stiffness"


Actually the issue is with the composite section for construction stage definition. Part 1 is activated in Active stage, i.e., CS1. Part 2 is also being activated in CS 1. Both the parts of a composite section can't be activated in the same construction stage. I defined a second construction stage and activated Part 2 in CS2. Now, there is no issue is definition.
