ANSYS Mechanical 2019R3 Updates

Chris Cowan
ANSYS Mechanical 2019R3 includes the new capability to create Material Combinations. A user can define a new combined material based on volume-weighted averages of individual materials. Previously, a user would typically prepare a spreadsheet to perform this type of calculation. A Material Combination can facilitate preparation of a simplified representative model for complex features like copper traces on a PCB layer for thermal analysis (for a higher fidelity approach to modeling traces, follow this link).

Material Combinations support most common properties for linear materials, including:
- Thermal Conductivity
- Density
- Specific Heat
- Young’s Modulus
- Poisson’s Ratio
- Coefficient of Thermal Expansion
- Orthotropic Elasticity
- Orthotropic Conductivity
