My model consists of a lot different element types and I have to manipulate a lot of PARAMETERS to get it solvable:

AutoMPC = YES,
MaxRatio = 1e11,
PRGPST = NO.

Does it mean that I have no appropriate load in my solution or did I "wring" my model with my PARAMETERS in a unusual way?

 

Any suggestion can help, with best regards, Michael.

The messages mean exatly what they say. At the end of the analysis, there are elements which have very low strain energies. This means that they have no load going through them. They are either in an unloaded area of the structure, or they could not be connected to the rest of the structure.

 

Note that these are "User Information Messages", not Warnings, Errors or Fatals.

JimB,

 

thank you for your answer.

As beeing only a user information message I think I do not need it, because I ckeck my model using other ways.

 

That's why is here my last question in this topic: Can I switch it off?
