Hi,

 

I am just simulating a canister which should be pressed together by two plates. The lower plate should be rigid and should have a proper position. The upper plate should move downwards (~50 mm).

 

Now I am getting the following Error:

 *** ERROR # 1904 ***
 SURFACE 4 refers to element 363732 of incorrect type.

 

The Surface 4 is the Canister. Element 363732 does not seem to be existent. The Model File is attached. I've tried to overcome the error but did not find anything. Please be patient with me since I'm an absolute beginner to Hypermesh and Optistruct.

 

Thanks for your help

 

 

 

 

EDIT: Both Meshes are Shells, it is not the Solid-Shell-Error mentioned in this forum before

 

EDIT #2: I think I got it but ran into another strange Problem. I will make a new thread for it. The Solution was, that I turned 'FACE_FORMAT' on for the curved(!) Canister. I think the geometry let the problems occurr
