Thanks so much for your response. I am still not getting any deformation in my model. A couple of points\/questions:
\nDid you make your model in spaceclaim or design modeller? I made mine in Design modeller, I imported the fibers as a DXF (chose frozen and selected line bodies) and then assigned them a cross section. I then drew a rectangle surrounding the fibers and then extruded (symmertically -0.25 microns both side). I did not union any of the bodies, I am not sure if this needs to be done. I modelled the single fiber(which works) without unioning in design modeler and it seemed to work fine.
\n I notice you have 2 coordinate systems, global and coordinate system ( I think for the beams). I have only one global. My beams are cylindrical so I don’t think a coordinate system for then is required, not sure if this is an issue.
\n My elastomer is hyperelastic and my beams are multilinear isotropic.
\nI went back to ANSYS version 19.2 and got the same result. So, it doesn’t seem to be version related.
\nDid you merge nodes in your model? from the literature body interactions-> reinforcement does not need nodes merged.
\n I also substituted my beam materials with the ANSYS default structural steel and got the same result. Which leads me to believe it is not my material.
\n So, perhaps it is something I am doing in design modeller? I am just importing all the beams a line elements from the DXF and assigned each of them a cross section. I do not union or merge the beams or the substrate.
\nI know ANSYS employees cannot download model files or archive file. I have my archive file, is there some way I can send it to you to look at it?
\nThanks so much for your time, it is greatly appreciated. I have been working on this model for more than a month, I feel i am close but am missing something small.<\/p>\n","protected":false},"template":"","class_list":["post-186648","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
