“Altair's client support has helped to use control material laws in such a way that we are confident in the validity and stability of our musculoskeletal models. They have always been very helpful in finding solutions for atypical problems. We appreciate the 2-level use of Altair's products, with the efficiency and ease-of-use of
Altair Inspire™ and the more technical in-depth control capabilities of the Altair HyperWorks™ software suite.”

Validation of Biomechanical Models
The main challenge in biomechanical modeling is linked to the complexity of the contact conditions and of the materials that can be inhomogeneous, anisotropic, nonlinear, strain rate dependent, etc. It is thus very hard to validate a biomechanical model due to the scarcity of experimental data and the lack of representation of variability. In addition, the studied phenomena are highly multifactorial, and have biological and chemical parameters that influence the mechanical behavior.
Biomechanical Simulation using Explicit Multi-Physics Simulation Tools
Dr. Léo Fradet, General Manager at Philomec believes that the company’s expertise in simulation differentiates them, as a majority of consulting companies offer only implicit FEM simulation. "Altair offers us the credibility we need to be relevant for our clients. Having explicit dynamic non-linear simulation tools allows us to answer to some of our clients’ most advanced problems. Also, Altair tools give us the opportunity to handle all aspects of the design and evaluation of a technological product.”
With primary expertise in biomechanical simulation, one of Philomec engineers' main focus consists in calibrating and validating material properties that are very specific to biological tissues. The constitutive models available are not always adapted for such applications. Dr. Fradet notes that Altair’s hands-on, customizable, and highly versatile tools are what they need to tackle complex and specific problems of this nature.
