We have been successfully using CAE for about 25 years to give our customers technical advantages in the implementation of their projects. Mathematical simulations make a key contribution towards saving time and costs by answering questions that could otherwise only be resolved by the construction of elaborate prototypes or the performing of tests. Alongside high-performance hardware and software, this also requires highly-qualified and experienced experts who are in a position to create meaningful links between theory and practice.
