How do I parameterize a User Defined RVE?

      I am trying to determine the relationship between a design parameter (in this case the diameter of the cylinder cut outs, see picture) and the resulting material properties. I was originally just setting all of these models up by hand in mechanical and doing the math myself to find average Young's modulus and Poisson ratio, but then I found Material Designer. However, the only way that I have found to use a User Defined RVE geometry was to copy and paste a body from SpaceClaim (as suggested in

      ). This means that I can't (a) import parameters from a CAD model (only in Design Modeler) and (b) I can't iterate over multiple diameters. Am I missing a step in Material Designer that allows me to work either with Design Modeler (so I can import dimensions) or to import data from a Geometry or Parameters cell?

      Hi MBenn:nCould you use Variable Material Solver to parameterize the feature of interest and solve for multiple design points? nSee Section 2.5 of the Material Designer Online Doc. nRegards,nJohnnn

      The problem is that I can't import a parameterized model, so there are no parameters over which to iterate. My plan was to use this tool, but I can't get the setup right. I was able to use this tool with other types of Material Designer RVEs, just not for User Designed RVE.n

      Are there any ways to import parameterized Design Modeler files into Material Designer? I have had success running variable tests on different types of Material Designer RVEs, just not for User Designed RVEs. n

      I confirmed that for user defined RVEs, the only available parameter in a variable material analysis is temperature (provided that at least one of the constituent materials is temperature dependent).nCurrently, we don't support geometric parameters in a variable material. nWhat you should be able to do, is to define these parameters on WB level and run DP studies.n n n

      Oh I see. Do you know if this is something that will be added in future iterations of the Material Designer? n

      Bump because I'd also like to be able to do this and would like to know if it is on the roadmap for MD.n
