Hello, 

 

I am trying to run linear buckling analysis on a structure that I created in HyperWorks.

 

I am getting a very accurate critical buckling load result when I apply a load of 100 N. However I get a Gram-Schmidt Reorthogonalization error when:

 

1) The applied load is 1000 N or 10 N (I tried multiple times, I am getting an error if the load is different than 100 N)

2) When I scale the geometry to cm's. (The model consists of nodes 10 mm apart from each other, connected with rod elements. The total length is 200 mm, the total height is 20 mm)

 

What could be the reason for getting this error? I am confused as the error occurs both when I increase and decrease the load. 

 

Thanks,

Muge Candogan
