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
