Hello everyone!

I am making static seismic analysis. I had calculated seismic U vectors Caesar's seismic wisard. X, Y, Z three vectors had calculated. In load case editor ı segrageted these vectors. But negative of Y vector is too big. Therefore, all cases which depend on -Y vector was failed. How can deal with this problem?

Thanks...

Without specific information, there can be no specific answer.

Validate/change your inputs for CAESAR's seismic wizard, find a new way to calculate seismic loads, or restrain your pipe better.
