"A simple, robust and predictive simulation tool, able to accurately identify the failure and the post-failure behavior of general composite structure was an analyst's dream until now. The innovative Firehole multi-scale approach provides an outstanding value to our customers because of its proven effectiveness and sound physical basis."

Simone Ragionieri,
SmartCAE General Manager

"Helius:MCT provides a unique and powerful analysis toolset. The integration with ABAQUS is seamless and user-friendly. The increased resolution of material failure mechanisms results in the ability to more efficiently optimize composite structures."

Products Helius: MCT

Helius:MCT has been developed with the composite engineer in mind. It has many features designed to deliver the most advanced technology in a practical, easy way. Here are just a few:

Easy To Adopt

Helius:MCT delivers a powerfully advanced analysis capability for composite materials - simply as an add-on to your current FEA platform.

Helius:MCT is easily employed via a graphical user interface (GUI) within the Abaqus or ANSYS simulation environment and integrates seamlessly with each solver. It is also available integrated and available within NEi Nastran.

Additionally, the Helius:MCT analysis process allows for quick and easy conversion of legacy models and requires only industry-standard material data.

This practical implementation enables you to realize the benefits of Helius:MCT’s accurate simulation with quickness and ease.

Material Inputs Made Easy

The Helius:MCT package comes equipped with a material library that is pre-populated with multiple sets of composite lamina material properties that are fully characterized for a Helius:MCT analysis.

Also included with the Helius:MCT package is the Helius:Material Manager. This accompanying tool provides a convenient graphical user interface (GUI) for creating a material file required to execute a Helius:MCT analysis. This file is referred to as a material data (or "mdata") file and when saved, will have an .xml extension. The Helius:Material Manager optimizes constituent-level information for multiscale analysis during an FEA solver run.


Robust Convergence and Computational Efficiency

A common problem with FEA of composite materials is excessive run times or inability to reach a converged solution. Composite materials exhibit very unique material behavior. General purpose finite element solvers, built to handle a variety of materials, simply cannot provide robust solutions for structures built of these complex materials.

Computational efficiency is inherent in the MCT method in that only a small number of equations is added to the computation requirements for a single integration point. In addition, Firehole Composites has developed the Intelligent Discrete Softening method (or IDS method), which has been incorporated into Helius:MCT to efficiently handle the unique material response of composites.

These design elements combine to produce an accurate result in a practical amount of time. Helius:MCT increases the run time for a typical structural analysis by only 2 to 3%.

Clear, Comprehensive, Easy-to-Understand Documentation

Helius:MCT is supported by a collection of documents written to provide the user with step by step guidelines to using the tool, as well as a technical background of the implementation. This includes detailed information about Mulitcontinuum Theory (MCT) and the various features that are implemented in the Helius:MCT User-Defined Material Subroutine.
