Fluid Dynamics Process Simulation

Our team »Fluid Dynamics Process Simulation« deals with rheological complex fluid flow problems and analysis of physical complex processes relevant for industrial applications.

Our competences include mathematical-physical modelling of material properties and industrial processes as well as development of fast, robust and efficient numerical algorithms for performing computer simulations of the identified models.

The expertise in modeling these processes and their efficient numerical solution is concentrated in the software platform CoRheos (Complex Rheology Solver), which offers validated and documented pre- and postprocessing as well as computing solutions for the software modules GRAIN and FLUID.

Example Projects


Simulation of PU Foam Expansion in Car Seat Manufacturing

Joint project in cooperation with Fehrer Automotive and Audi in which our software FOAM is used and further developed.



Potting Process Simulation of Electronic Devices

In the project SOVEB we simulate this process with FLUID so that companies can optimize their production steps.


Characterization and Modelling of Long Fiber Reinforced Thermoplastics

We contribute our simulation expertise to the AiF project.


RIM Processes of Polyurethane Foams

In the project FoamInTextil we simulate the foam filling process of Polyurethane foams.


Digital Twin: Foam

In this project, we are using our digital twin to digitize the development, design and production processes for foam components, taking into account the foam properties.


Simulation of Granular Mass Flows

Application and project examples for the simulation of granular mass flows.


XERIC: Climate Control System for Electric Vehicles

The XERIC project is developing a new climate control system that is more energy-efficient in battery powered electric vehicles.



The aim of the BMWi project CoPool is the development of a compatible software CoPool, which allows a more precise simulation of flow and heat exchange.


Analysis and Optimization of Paper Machine Clothings

We analyze and simulate the behavior of press felts.

Software Products


The software solution, Complex Rheology FLUID Solver, has been developed to simulate the melting and flow behavior of polymer suspensions, such as in the injection process of a fiber suspension.


GRAIN is an infrastructure for the design of products and processes which involve granular media.


Our FOAM solver simulates the expansion process of PU foams in any given geometry and offers the possibility to calculate the foam formation process as well as the resulting foam density in advance.
