I am using an orthotropic material model in an Explicit Dynamics model. My geometry is curved, so I was wondering if it is possible to create an element coordinate system that 'curves' with the geometry so that my elastic modulus on the through-thickness direction is actually in the through-thickness direction with respect to the geometry?
At the moment, the orthotropic model follows the global coordinate system and I can't create another coordinate system that follows the curve of my geometry. In Static Structural, I can create an element coordinate system that allows me to have the orthotropic model in the correct directions, however, in Explicit, it is grayed out and I can't find any reference to element coordinate systems in the documentation.
Does anyone have any tips on dealing with explicit dynamics, orthotropic models and curved geometry?
