Fraunhofer Institute for Algorithms and Scientific Computing SCAI

Software and Services for the Automobile Industry

Fraunhofer SCAI cooperates with the automotive industry in many areas, both with manufacturers and suppliers. Topics of these collaborations are, for example, the optimal use of transport or storage capacities as well as materials, the robust design of vehicle components or the solution of multidisciplinary problems in vehicle development.

Closer to Reality with Multiphysics

Multidisciplinary simulations become increasingly important to meet the growing demands on the quality of simulation results. Our software MpCCI is the world's leading tool for multiphysics simulations, which require a combination of proven application codes for individual disciplines (flow, structure, acoustics, heat etc.).

Better Crash Simulations due to the MPCCI Mapper

The models used in crash simulations are idealized – they usually do not take production-related local changes in geometry or material properties into account. The MPCCI Mapper helps to increase the informative value of crash calculations by integrating the results of manufacturing history into the crash model.

Getting a Grip on Variations

The robustness and quality of production processes can suffer considerably from variations in material properties, geometric details and process parameters: Robust Design helps minimise development times and costs.

The Turbo-Solver

Simulations often require the solution of large systems of equations with millions of unknowns. Algebraic Multigrid (AMG) is a fast and efficient technique for solving such equations and can be individually integrated into software packages.

SAMG is a software library of AMG-based routines for the high-efficiency solution of large linear equations systems with sparse matrices.

Efficient Utilization of Materials

Our AutoNester Suite optimizes the automatic arrangement of cut images on fabric webs and metal (AutoNester-T) as well as leather skins (AutoNester-L). The software is able to nest any set of pieces within a very short time in an optimal way, minimizing wasted material, while taking into account various types of constraints.

Cost Reduction by Optimized Packaging

Our PackAssistant software ensures optimal packing of identical parts in containers, thus reducing storage and transport costs and reducing the time for packaging planning.

Reducing Costs and Safeguarding Planning (by Logistics Simulation)

The optimal utilization of production system capacities and in-house logistics processes requires efficient and careful planning. This enhances productivity and keeps investment costs down. Material flow simulation reveals optimization potential within an operation and safeguards the decisions taken.

Comparison of Finite Element Models with ModelCompare

ModelCompare allows a simple and direct comparison of two similarly discretized finite element models and calculates differences in the geometry, lattice, material ID, or thickness.

SimCompare

SimCompare is a tool for detecting events – in this context deviations, such as anomalies or strange variations in deformations – arising in the results of similar simulation runs for crashworthiness analysis using finite element (FE) models.

MESHFREE

In common simulation workflows, the preprocessing step of grid generation and grid adaption is time consuming and leads to substantial costs in product development. With MESHFREE, the Fraunhofer institutes ITWM and SCAI have developed a solution that follows an innovative point cloud approach which allows engineers to analyze their product design without the deficiencies that come along with meshes.
