nastran msg warning no element connection for node directions

Hi everbody,

 

I'm doing a nonlinear calculation using SOL 601,106 Advanced Nonlinear Statics. I receive the warnings:

 

No element connection for node 1 directions 4, 5,6

Similar warning suppressed for 75807 other nodes

Nodal degress of freedom without element connection have been fixed for data input

 

I understand that there are no rotational degrees of freedom of the used CTETRA(10) elements. Therfore, in my opinion, this warning is at least in my case superfluous. Is there any method to get rid of it?

 

Thank you in advance

Hey Muppets!

 

I do not think there is one. Since this is an issue in communication between ADINA and NX Nastran I think this is no changeable stuff...

 

... however this warning do not bother me, so I haven't really searched for a solution.

 

Good luck!

Łukasz

Hello!,

The reason of the error is because PARAM,AUTOSPC,YES is ignored by SOL601 ADINA solver, only a few PARAM variables are supported.

Best regards,
Blas.
