Mutliscale designer with abaqus
Hello,
Have anyone tried to use the mutliscale designer with abaqus as solver. I intend to use multiscale designer to generate a material model that will be used to model progressive damage. I wanted to know if there is any known problem with using abaqus as solver. I see in the manual that element deletion is not supported while using multiscale designer with abaqus. Has this been fixed is there any update on this.
Regards

i tried to run simulation of a simple tension test (a shell model in abaqus) using multiscale non linear material model following the manual. But the results doesnt capture non-linearity and stress just keeps increasing. But the virtual tension test(UNT/C) in MDS seems to give more reasonable result. Thats why I was wondering if this problem is specific to abaqus, have anyone tried it?
Altair Employeeare you looking at which stress results?
At least for OptiStruct, there's the 'regular' stress, homogeneized, and there are a bunch of UVARs, representing the multiscale results, that involves the more detailed results, such as failures, stresses in each phase, and so on.
Did you find these?
i don't think there's any issue with using Abaqus as solver with MDS.
I believe the embed documentation covers the steps and limitations concerning this connection.
In MDS as far as I understand, you would embed the failure modes into the material model, and then get a uservariable as an output, pointing for possible failures or not, so there will not be explicit element deletion itself, but a 'flag' showing for failures for each element.
