Hello Sir,


I have attached the file for which performing modal analysis. If I talk about the connections then, all the outer two holes of feet are bolted to pedestal. The pedestal is welded at boundaries to deck plate and finally deck plate is welded at boundaries to foundation made up of I beams. Also the cylinders are bolted to cross head guide supports and they are bolted to compressor frame. Also those cylinders are bolted to T supports and they are welded to deck plate.

I tried but getting same off values of frequency as I have shared while ago.

I would be happy sir if you can help me with my modal. Let me know after having look to my modal.

The ANSYS version is R1 2019
