Hello!

I am having issues with a simulation of mine. I have built a ball, a perfect sphere, modeled it as a solid body, and created a special carbon fiber epoxy material to use for the ball. The carbon fiber is linear elastic orthotropic, so I need to define a reference geometry when creating the material. However, since I have a spherical geometry I don't know which reference to use. I have searched online and on this forum, but the best I could find was how to set it for a cylindrical geometry, as in this guide: 2011 SOLIDWORKS Help - Isotropic and Orthotropic Materials . To clarify, I want to do exactly the same thing as the linked guide does for a cylindrical geometry but for a spherical solid body geometry, as in one axis (eg. Z) being the radius of the sphere, and the other two axises (eg. X and Y) giving the plane tangential to the sphere's surface for every point on the spherical surface. Is this possible?

Thankful for any help!

Hi Adam,

It is not currently possible to apply orthotropic material properties to a spherical coordinate system. It is a current limitation of the software. You are stuck manually making local coordinate systems and split line faces if you want to accomplish something like that.
