I just have a question at this point, as I havne't gotten to far into this project as of yet. I have a curved laminate panel, say 180-deg so half a cylinder. If I apply an orthotropic material with the reference CSYS at one end/edge, I assume the material will be applied uniformly as such, without considering the lay of the curve. Otherwise, you would be able to apply the material to the surface. I ran a test part, and sure enough I get a sort of strain discontinuity at the angle where the primary direction changes.

My question is how to properly simulate this type of structure/material combination, or is it simply beyond the scope of SWSim? I understand if there are flanges and such, that they can be made as seperate parts and have different ref CSYS to apply the material, but over a large curved section it become tedious (and rediculous) to try to parse into essentially a polygon with tangent sections.

Has anyone done this type of analysis and can provide any insight? Thanks!

just use multiple coordinate systems and break the surface up into some sensible number and apply different orientations using different cord systems.

If you use GeoSTAR you can base it on the element coordinate systems, which typically would suggest the use of quads as opposed to tria's. the above approximation usually works well enough.
