PolymerFEM New Features: Version 6.1.0

PolymerFEM New Features

2020-02-28: We are excited to announce the release of version 6.1.0 of MCalibration and PolyUMod. This version is available for download right now.

PolyUMod Improvements

Supported Platforms:

Improvements:

Significant run time improvement when running PolyUMod with Abaqus on Windows computers. Some FE simulations that use PolyUMod will now run 2X faster!

The name of the license server can now also be specified by the environmental variable “RLM_LICENSE”

MCalibration New Features

All Abaqus hyperelastic models (except Marlow) are now supported by the MCalibration internal solver.

This includes both compressible and incompressble versions of each model.

All Abaqus hyperelastic models (except Marlow) with Mullins damage are now supported by the MCalibration internal solver.

This includes both compressible and incompressble versions of each model.

All Abaqus hyperelastic models (except Marlow) with linear viscoelasticity are now supported by the MCalibration internal solver.

This includes both compressible and incompressble versions of each model.

The Abaqus LVE model has 2 additional parameters: sum_g and sum_k

g1 = real_g1 * sum_g / sum(rel_gi)

Here: g1 = 0.3 * 0.5 / (0.3+0.3+0.3) = 0.167

All Abaqus hyperelastic models (except Marlow) with linear viscoelasticity and Mullins are now (preliminary) supported by the MCalibration internal solver.

This includes both compressible and incompressble versions of each model.

Added internal solver support for the LS-DYNA Hill-Storakers hyperfoam model.

Added a pre-defined template for a temperature-dependent Abaqus PRF model.

Added a pre-defined template for a temperature-dependent Ansys Bergstrom-Boyce (BB) model.

Added internal solver support for the Abaqus Holzapfel-Gasser-Ogden model.

Can now resample DMA data files.

Added support for log-scale interpolation in the data tab.

Improved graphs with log-scale data.

Added initial support for optimizing parameters in logarithmic-space.

Additional MCalibration Improvements

Better error messages when running a load case that fails when using the Abaqus solver.
Improved the parameter bounds in the Ansys Bergstrom-Boyce (BB) model.
Significantly improved the initial guess of material parameters for the Abaqus linear viscoelastic model when DMA data is available.
Now correctly uses the anisotropic solver when using the Abaqus elastic-plastic-Hill (Potential) material model template.
Improved the internal implementation of the Ansys MISO model.
Improved the internal implementation of the Ansys MISO Creep model.
Many minor bug fixes.
