Fraunhofer SCAI

Fraunhofer SCAI’s business area Multiphysics offers research capabilities, software development and applications modeling services to its customers and partners. The institute combines mathematical and computational knowledge with a focus on algorithms bringing benefits to customers.
Multiphysics s simulations still is an open and active field of research with respect to numerical algorithms as well as modelling of the combined physical effects.
In the context of publicly funded projects and in cooperation with partners from industry and academia the business area Multiphysics does research on such open questions. The results and experiences from these projects will be integrated in MpCCI software and solutions for industry.

Product details

Multiphysics solution
The MpCCI interface software is a vendor neutral solution for co-simulation and file-based data transfer. MpCCI supports a growing number of commercial as well as research simulation tools in different engineering disciplines.

The MpCCI software is offered as a licensed product and distributed by scapos AG.

MpCCI CouplingEnvironment

The MpCCI CouplingEnvironment has been developed in order to provide an application independent interface for the direct coupling of different simulation codes. MpCCI CouplingEnvironment has been accepted as a ‘de facto’ neutral standard for simulation code coupling and provides a multi-physics framework. Within the MpCCI CouplingEnvironment the engineer can combine several ready-to-use models, define the application field and choose for the best-fit coupling method.
MpCCI CouplingEnvironment has already successfully been used in various application domains:

  • Fluid-structure-Interaction for aero-elasticity and flexible components in machinery design
  • Thermal stress and vibrations in turbomachinery applications
  • Combined system and 3D continuum models for vehicle and machine dynamics
  • Coupled fluid and radiation for automotive thermal management
  • Thermal and magneto-hydrodynamic effects in electrical components
  • Fluid-structure-interactions in bio-medical applications

Product Features

  • Explicit and Implicit coupling method
  • Gauss-Seidel, Jacobi coupling algorithm
  • Support for intensive and extensive quantities
  • Co-Simulation analysis type: steady state, transient, mix coupled analysis
  • Mapping for different mesh discretization with handling for geometry deviation
  • Automatic configuration for fast and robust FSI (coupling scheme, algorithm, relaxation parameters, …)
  • Predefined coupling specifications (FSI, Thermal, MHD,…)
  • Support most of the leading commercial codes for fluid-dynamics, structural analysis, electro-magnetic and other disciplines.


The MpCCI FSIMapper is able to read various CFD, EM export formats as well as input decks for Abaqus, Ansys, LS-DYNA, VMAP and Nastran. The two meshes between which the interpolation shall take place have to be 2-dimensional surface meshes in a 3-dimensional space. The quantities that can be read and mapped are film temperature, wall heat transfer coefficient, the wall heat flux, standard and complex pressure, and force densities.

A specific feature is the possibility to compute »Average over Rotation Axis«: if the CFD model uses the frozen-rotor option, the quantity values from the frozen-rotor computations will be averaged and these quantity values will be mapped to the CSM model. The mapped quantity values can be imported into Abaqus or Nastran models.

Furthermore, it is possible to compare two geometries with the MpCCI FSIMapper.

Product Features

  • File-based mapping solution
  • Robust and efficient algorithms
  • Handling non-matching geometries
  • Automated model positioning
  • Fourier Transformation
  • Handling cyclic symmetric geometries
  • Volume based temperature fields
  • Interactive visualization
  • Batch capability

Electro-magnetic-induced Vibrations in Electrical Engines:
The rotating electro-magnetic field in E-motors produces periodic forces which excite vibrations of the structure and noise in the surroundings. On the one hand, the electro-magnetic forces are computed in an EM-code. On the other hand, the vibrations are computed in CSD-codes. The tool MpCCI FSIMapper builds the missing link between both simulation disciplines: it maps the electro-magnetic forces from the EM-simulation as boundary condition to the structural vibration simulation.
