Error when using SOL 200 1

[majidpouya]

Hi everyone.
The following UFM is reported when I try to perform an optimization procedure(SOL 200) on my model. In the model some parts are attached to the residual model through external superelements.
"SYSTEM FATAL MESSAGE 4252 (SEMA)
MATRIX XAAV FOR UPSTREAM SUPERELEMENT 1 DOES NOT EXIST."
Nevertheles,the normal mode(SOL 103) runs are perfomed succesfully on the model.
Has anyone had the same experience?

Hello to everyone,

Could anyone give me some information about 1-D GAP elements i.e what they do? how can be modeled? Are they can be used in linear calculations also?

Thanks
