ERROR 160

kkandra

Hi friends,

Please help me out!!!!!

*** ERROR # 160 ***

Gram-Schmidt reorthogonalization did not converge. This is caused by

ill-conditioning of the shifted matrix in Lanczos run.

(e.g. zero lower bound specified for a model with rigid body modes.)

Solver error no. = 728

subcase id = 1

This error was detected in subroutine splncz.

This error occurs in module 'slvdrv'.

How to solve this error?...

Thanks..

Hello,

You should do Eigenmodes analysis first to see if any rigid modes are there. It's a bad contact or Assembly problem. Then fix it and it should run perfectly.

I am facing the same issue, But I'm facing it after doing a free-free mode analysis
