Hi all,

We have a very big file & we need analys the portion of that .is it possible in CAESAR 5.2

You can't analyze a "portion" of a model. What you can do however is:

1) Make a copy of the model.
2) Edit the copy and delete those parts you don't want to analyze.

As long as the remaining portion has the proper boundary conditions (and loads), your analysis will be valid.
