Dear Friends
I am new to SKTO.
Every time I tried to get the confined concrete model when I model a rectangular fiber section, the software crashed.
I tried on two versions of STKO, but I still have the same problem.
When I used the unconfined concrete for both core and cover concrete, I have no problems.
Any solutions?

Sorry for the inconvenience.
