Birth and Death Elements

Hi,

 

I am trying to use birth and death elements in an analysis.

 

I want an element to be "Born" on the first time step and "Killed" in the second time step.

 

I am using the NX Nastran advance nonlinar solver and have the set the solver up as shown below:

Analysis 2.PNG

However, when I run the analysis I get the following errors:

 

Error 1.PNGError 2.PNG

 

Can anyone advise where I have gone wrong with the solver?

 

Any help woul be greatly appreciated.

 

Cheers,

Craig

What version of Femap are you using? Do you have more than one version Femap installed? I do not believe this error is a result of setting up birth/death.
