I would like some help with importing data from an Abaqus *.inp file through the external model in ANSYS Workbench into ANSYS Mechanical. My aim is to read in nodes and elements with local coordinate systems associated with certain groups of elements to implement anisotropic materials behavior.
I succeeded in importing nodes and elements with named selections of element groups. I also managed to import local coordinate systems that I need for each named selection to define anisotropic material properties.
Here is one of the local imported coordinate systems:
This is one of the named selections, that groups a number of elements:
I would like to be able to assign an anisotropic material to the entire plate (that's easy) and then use local coordinate systems to define the orientation of element groups. This does not seem to be possible.
In my Abaqus input file I defined the coordinate systems with the orientation command:
*ORIENTATION, NAME=CS-56, DEFINITION=COORDINATE
The element sets were then associated to the coordinate system as follows:
*Elset, elset=Grain-56, ORIENTATION=CS-56, MATERIAL=BetaTi_r, RESPONSE=TRACTION SEPARATION
8789, 8790, 8934, 8935, 8936, 9079, 9080, 9081, 9082
9226, 9227, 9228, 9229, 9230, 9371, 9372, 9373, 9374
9375, 9376, 9377, 9378, 9379, 9380, 9381, 9382, 9383
I was unfortunately not successful in importing local coordinate systems that are directly associated to the named selections in ANSYS Mechanical.
But even worse, the named selections in ANSYS Mechanical do not seem to be useful either. If I, for example, want to do a material assignment to a named selection, the dropdown window is empty even though I have all the named selections from the element sets.
Does anybody have a clue on what to do about this situation? Any way forward or alternative approach would be great. I am currently generating the *.inp file in MATLAB and could formulate it differently if there was any merit to it.
Thanks and best wishes
