Three different materials can be set up in MSC Apex Generative Design.:
Isotropic Material
The properties of Isotropic material are uniformly in all directions. Therefore, only one Youngs Young's modulus, one poisson’s Poisson’s ratio and one Tension (Tensile) Strength is needed.

3D Transversely Isotropic Material
The properties of 3D Transversely Isotropic material are diretional directional dependent. One direction (axial / build direction) differs from the two others other in-plane directions. The x-axis is always the build direction, the y- and z-direction are the in-plane directions. As an input the Youngs Young's modulus for the build direction as well as for the in-plane directions (Ey=Ez) are needed. FuthermoreFurthermore, the Shear Modulus and the two Poisson’s ratios for in-plane and axial are desired. All further necessary values which are necessary are calculated in the background.
For the material limits the Tension Strength in build direction (Axis) and for the in-plane directions as well as the transersal transversal Shear Strength can be set up. With the Failure Criteria FFF Thumb Rule and with the direcitonal dependet directional dependent Tsai-Hill the different material limits differences can be considered.
Optional the Compression Strength can be filled inset up. With the directional dependent Tsai-Wu Failure Criterion the difference between tension and compression can be considered besides the directional dependency.

3D Orthotropic Material
The properties of 3D Orthotropic material are diretional directional dependent. For every main axis a different Youngs Young's modulus is needed . As as well as shear moduli Shear Moduli for all planes and the poisson’s Poisson’s ratios.
For the material limits the Tension Strength in build direction (Axis) and for the in-plane directions as well as the transersal transversal Shear Strength can be set up. With the Failure Criteria FFF Thumb Rule and with the direcitonal dependet directional dependent Tsai-Hill the material limits differences can be considered.
