About Vonstein & Partner
The engineering office Vonstein & Partner is an engineering service company specialized in numerical simulation, based in Brilon (South Westphalia). The company supports industrial enterprises, design offices and freelance designers, especially in mechanical and plant engineering, in introducing and applying 3D simulation in product development. Its services include FEM simulation, CFD flow simulation, fluid-structure interaction (FSI), multibody simulation, strength verification according to the FKM guideline, as well as the optimization of products and manufacturing processes, for example for solar thermal collectors or the cooling of injection molding tools. A key focus is the use of open-source simulation software such as Code_Aster and Code_Saturne to make the entry into simulation affordable for SMEs. In addition to calculation services, the company offers simulation strategy development, training and support, as well as the introduction of knowledge databases for simulation results. Its customers include REMBE GmbH and EJOT GmbH & Co. KG, among others.

Processes and Methods
FEM simulation (finite element method)
Virtual design and strength assessment of components, assemblies and machines, including static verifications and fatigue strength according to the FKM guideline.
CFD flow simulation
Analysis and optimization of components with internal or external flow, such as cooling channels, pipelines and valves, with regard to pressure loss, cooling performance and noise.
Fluid-structure interaction (FSI)
Coupled simulation of flow and component deformation, e.g. for valve housings, pipelines or solar thermal collectors.
Multibody simulation (MBS)
Simulation of dynamic systems with moving components in machine development.
Open-source simulation software (Code_Aster, Code_Saturne)
Use of license-free simulation tools to make simulation economically viable for SMEs and freelancers.
Simulation strategy and training
Company-specific introduction of simulation in product development, including know-how building and knowledge database.
