hi, can any one help me out from this
I am working on intake and exhaust duct analysis of DG, and i need to analyze for negative pressure so in Caesar is it possible to analyze for negative pressure? i am using Caesar version 12
In the past conversation related to this type of comment it is observed that buckling is not able to do in Caesar, so if not possible in Caesar then which tool is preferable for negative pressure piping analysis

observation: I have tried for the same pressure with positive and negative values in Caesar and i got minor change in support load and same in the stress result

regards,
Pradeep
