Hi，Recently encountered this problem
*** ERROR # 4002 ***
Running RADIOSS engine, 2 ERRORs and 0 WARNINGs have been detected.
They are listed below.
ENGINE ERROR:
** RUN KILLED : ENERGY ERROR LIMIT REACHED

I can't figure out the reason about it，element？velocity？mass？ I don't know，
The workd ，The outer plate is a steel plate and the inner plate is a composite material.
But in ，I just make some changes，offset some element for composite，then，the error occurs。
Can someone help me check the reason of the error?

Are these elements part of contact?
I don't know what do you mean？I'm confused abou the contact between the rigid wall and the B-pillar?
In addition, there is a downward slide after the collision, how to prevent this from happening

I mean the elements which were offset from their original position, are they part of the contact interface?
To avoid sliding, constraint the rigid tube.

The offset element Tie with the original element, but is not in contact with the rigid wall,
and how to restrain the rigid wall from slipping？
Please check the .fem file，thank you。

OK, I thought it is a tube which is made rigid. I will check and update you soon.

Thank you，could you provide the method about how to constraint the rigid tube？
In the.0001 file ，the error messages details shows following，
ERROR : NEGATIVE STIFFNESS NODE
Could you give me some advice ？ How to solve this kind of question？thank you
Altair EmployeeThe error could be due to contacts or due to material properties. If you have unrealsitic material properties, such error pops up.
Please check the contacts, material properties and units.
