Totalsim Workflows in Electronics and Battery as a design tool:

TotalSim's motor-sport technology has been borrowed for the construction of electronics and battery,  workflows that require the use of complex models to calculate the voltage performance of a battery cell or its behavior using methods with computational fluid dynamics. TotalSim's workflows create a digital twin to the battery process. Our technology was born in the automotive F1 race track and can be employed to address critical electronic circuit & battery issues.

The following workflow capabilities provide an overview of what can be accomplished when using our StarCCM+ workflows for the most complex challenges that necessitate CFD technology.

Benefits We Provide

Working with virtual modeling and simulation of fluid flows allows you to accelerate your design process using software such as Star-CCM+ or OpenFOAM. This reduces the number of physical prototypes and testing, while still evaluating all necessary conditions. Our engagement ranges from CFD consulting, to training, to customized workflows to meet your specific needs.
