Design Principles

"Simulation accuracy is directly proportional to the fidelity of the input material data and model selection."

In manufacturing, especially for complex parts like those in the automotive sector, accurate simulations are crucial for efficient die design and to minimize costly physical prototyping. By understanding the impact of material model parameters, designers can reduce trial-and-error, leading to faster development cycles and optimized production outcomes.
