Automotive. CompMechLab Experience
In order to be able to meet customer's requirements for shorter development times, CompMechLab's development process takes the form of Simulation Based Design engineering. The application of CAE methods allows our simulation specialists to set the direction in the early stages of development for achieving the functional objectives in a range of areas: Crash Analyses, Occupant Protection, Strength Calculations, Rigidity Calculations, Vibration, NVH, CFD Simulation, Thermo-Mechanical Analyses and others.
Crash analysis: Implementation and Methods
Finite element model development and simulation based design for complete vehicle.
CompMechLab develops vehicle bodies for the automotive industry, in the frames of the high standards of functionality requirement. Development includes the passenger cell, floor pan, front-end structure, roof module and closures. The responsibilities of the body development include the precise definition of the strength, rigidity and crash behaviour of the bodywork.

Latest News in Automotive
CONTACT and BETA CAE Systems Launch a Development PartnershipCONTACT Software and BETA CAE Systems have launched a development partnership to incorporate the field of product validation into Product Lifecycle Management (PLM). This will enable two leading software manufacturers in their relevant fields to bundle their know-how: CONTACT in PLM and BETA in the field of simulation. The cooperation aims to close the gap which has previously existed between the worlds of CAD and analysis with an integrated range of solutions. This kind of trans-discipline support in PLM context is in particularly high demand among automobile manufacturers and suppliers, as well as other sectors in the manufacturing industry, to speed up the development process and improve the traceability of verification results.
