Hellow

I have only one year of experience in stress analysis and in Caesar II, and I have many doubts, I hope that my questions aren´t too stupid, please sorry......I`ll try to explain it

I have been trying to insert a reinforced pad in a tee where three pipes are conected, and I don´t Know How do I make?, please help me....

Other problem with Caesar II: well I have been trying to insert a metallic expansion joint, but the data requested by Caesar II isn´t supplied by all the vendors, and I have some stifness like Axial Stifness, Trans Stifness and Torsion Stifness, but I need torsion stifness and Effective ID, please what is the effective ID? and Which data do I need for metallic expansion joints?

Thank you for your help.

Best regards.
Nala.
