MultiMech 19.0 Delivers Expanded Simulation Capabilities and Increased Speed

Release Improves Breadth and Run Times of Multiscale Composite Simulations

Omaha, Nebraska: MultiMechanics, a developer of multiscale composite modeling and simulation software, has announced the release of MultiMech 19.0.

Composite materials are currently transforming the transportation industry by improving efficiency, lowering emissions, and decreasing fuel consumption. However, the current process for adopting these advanced materials is time sensitive and can cost millions in testing and certification. To help address these challenges, MultiMech 19.0 delivers new material models, new damage scenarios, faster run times, and expanded integration with commonly-used FEA systems.

Highlights of this release include:

New bi-modulus elastic model

This addition will enable engineers to better capture the mechanical behavior of carbon fibers. In addition to exhibiting nonlinear elastic behavior at small deformation, carbon fibers also possess different mechanical properties in tension and compression, making them especially difficult to model and simulate. MultiMech 19.0 allows engineers to more realistically predict the behavior of these materials.

Solver speed-up of 1.5x

The solver speed-up will allow engineers to take advantage of the accuracy of a concurrent multiscale approach while benefiting from increased speed.

Parallel runs in Optimizer

This will allow engineers to reduce the runtime of DoE jobs using MultiMechanics’ Optimizer and get answers faster.

New material models

MultiMech 19.0 implements new material and failure models, including continuum damage models for orthotropic materials and new damage laws that will allow users to capture unique material behavior with higher accuracy.

Enhancements to nonlinear solver

MultiMech 19.0 features improved automated time step and optional displacement convergence check, as well as the ability to check for large displacements in the nonlinear solver.

Material Database

The MultiMech material database has been redesigned and enhanced to speed up the workflow. Users can now create their own database of material cards to be used with MultiMech, including material definitions for individual constituents, as well as define an entire Representative Volume Element as an entry to the material database. It is also very easy to create, import, export and share a material database with other users within an organization.

Virtual DMA

MultiMech 19.0 includes a streamlined tool to run Dynamic Mechanical Analyzer (DMA) tests virtually. With this tool, users can easily and quickly characterize the viscoelastic behavior of complex microstructures in all directions, at different temperatures and frequencies.

ANSYS DX Integration

With the new ANSYS DX integration, users can perform Optimization studies at both the macro and micro scale using ANSYS DX’s unique capabilities.

“As the use of material modeling and simulation software expands, material scientists are demanding more accurate results without compromising speed and functionality, as well as easier and more integrated workflows. MultiMech 19.0 marks the significant progress we have made towards closing that gap,” stated Dr. Flavio Souza, President & CTO of MultiMechanics.

MultiMechanics will hold a release webinar on Thursday, April 11th. To register, please visit


MultiMechanics develops MultiMech, a multiscale material modeling and simulation software platform that virtually predicts failure in advanced materials at an unprecedented level of speed and accuracy. One of its first projects was helping the US Army Research Laboratory explore impact applications, and the company has since evolved to specialize in helping material manufacturers and their clients better understand how composites will behave under extreme conditions. MultiMechanics was founded in 2010 and is based in Omaha, Nebraska.
