Re: Importing Equivalent Plastic Strain
Correction to the importation of PEEQ. Only the last time increment was taken into account.

Re: Importing Equivalent Plastic Strain
Is it really just these addition:. https://github.com/berndhahnebach/FreeC ... ed8e879053 ?
do yo have some simple file to test with?

Re: Importing Equivalent Plastic Strain
Yes, these are the only changes.
Here is a simple example.
Please note I have chosen user defined time step control since I wanted to be sure results would be available for several time increments.
However, I suggest to remove the "DIRECT" command since in that case, the automatic time step control is deactivated, which is really a pity because in non linear analyses there may be very large varations of the necessary time increments (large when the response is linear and small when there are strong non linearities).
*STATIC, DIRECT
0.1, 1.
For example, if I keep DIRECT in this example, the computation fails to converge and there is no result.
DIRECT should not be the default behaviour.

Re: Importing Equivalent Plastic Strain
@sodelo:
it is about the property "Iterations User Defined Incrementations"
means there are three choices from your point of view:
- nothing
- no Direct, but user defined time step length
- Direct and user defined time step length
at the moment there are only two:
- nothing
- Direct and user defined time step length
See https://github.com/FreeCAD/FreeCAD/blob ... #L712-L736 You may make a better proposal
I'm no good at all the different possibilities of CalxuliX. I mostly need linear static analysis ...

Re: Importing Equivalent Plastic Strain
changed it with git commit f29424c
IterationsUserDefinedIncrementations sets the Parameter DIRECT
IterationsUserDefinedTimeStepLength sets the usage of user defined time steps
use Time Step Length and Time End to adjust the time steps

Re: Importing Equivalent Plastic Strain
I am using non-linear material and geometry settings in the CalculiX object and the stress results I get are indicating that all is well. However, when I try to display PEEQ, I find that this radio button is greyed out. Is there a special trigger for enabling PEEQ output? Thanks. Harry
Re: Importing Equivalent Plastic Strain
would you post a simple example file to test with?
Re: Importing Equivalent Plastic Strain
Here is an example Bernd. Stresses seem OK, but PEEQ output unavailable. Thanks for helping out !
Re: Importing Equivalent Plastic Strain
it is grey because there is no peeq
open your file and run
or have a look in property editor of result object
Why is there no peeq? I do not know, I will have a look at this.
bernd
open your file and run
Code: Select all
App.ActiveDocument.CalculiX_static_results.Peeq
Why is there no peeq? I do not know, I will have a look at this.
