It's very hard to answer to your question.
I guess you to look for a good book with practical examples because the correct answer depends on many parameters.
The quickest answer is : all the result postprocessing is useful for get the correct response. If the results change small when you look...
The post buckling analysis is very sensitive analysis.
Do you try to take a step before analysis of buckling with a load of 90% of the first eigenvalue analysis of buckling not preloaded ?
Remember to active the nlgeom parameter to on.
After this, you can use this new values for imperfection...
Some know I can get a list of abaqus error message with possible solution ?
I cannot find any solution for :
***ERROR: Issue cannot be deleted Not all data Released.

You can create a group with curves you want to look for associativity.
Then you can add to this group the node associated with curve using "group - node - on curve" command.

You can display the elements in element set ErrElemMissingSection in visualization tools to understand the problem.
Try it and tell me the result.

I know that the better way to characterize a rubber it is possession of the esperimental data.
However, do anyone know the values maximum and minimum of calculation models coefficients (C10, C11 Neo-HOOKE model, for example) for the different kind of rubber ( natural, NBR, HNBR, etc) ?
Thanks...
I didn't explain my problem well.
Example I had to make a cube 1CM x 1CM x 1CM and I insert the parameters 1, 1 and 1.
I checked solidworks unit and I saw that the unit is mm.
If I change to MM solidworks change the parameters to .1,.1 and .1.
I don't want this, I want to change unit from MM...
I made a solidworks part with parameters in cm.
But soliworks part is set to mm.
Do someone know a method to multiply all parameters for 10 ?
I don't want to use the scale feature but change all parameters values.
Thanks for the answer,

It's true, if you compare a bricks and tetrahedons model with the same DOFS.
If you use parabolic tetrahedons model with elements much smaller than in a bricks model the response is different.
The use of tetrahedons are very usefull because you can use automatic mesh to generate the model. So...
I used the version 7 to made the FRF fuction with the following procedure:
Model Response
Response Evaluation
Damping ratios Viscous 0.015
ALL
CResponse Set Create Phisical DOF
Node
Select DOF...
I know the limitation about ratio of the tickness and the model dimension( > 1/10).
Does someone know if exist a limitation about the ratio of the tickness and the minimum element dimension ?
Thanks,
