ARTEQ Numeric Simulation

We use numerical simulation to support you with your tasks. We usually use the finite element method (FEM) for structural-mechanical analyses such as strength calculations, thermomechanical load simulations and analyses, and computational fluid dynamics (CFD) simulation for fluid-mechanical investigations. If the interactions between the mechanics and the flow are to be analyzed the fluid-structure interaction (FSI) simulation is used. Compared to conventional experimental analyses, costs and time are saved significantly, particularly in the product development process.

Mechanical, thermal and dynamic FEM simulation

Benefit from our many years of simulation experience! With numerous successfully completed projects, we stand as a reliable partner in engineering services, offering active support from the initial idea to the final product while providing solutions for the entire development process.

The Finite Element Method (FEM) simulation describes physical phenomena using partial, location-, and time-dependent differential equations. It is the most widely used method for calculating complex structures across various disciplines. In mechanical engineering, it is primarily used for strength calculations, mechanical and thermomechanical load simulations.

With the right algorithms, continuum mechanical relationships can be defined, and overall system behavior can be efficiently analyzed.

Take advantage of our extensive experience and benefit from the advantages we offer in the context of holistic product development in various fields. Our services include:

Static analyses (linear and nonlinear systems)
Dynamic analyses (vibration behavior, natural and external frequencies, harmonic behavior)
Fatigue and service life evaluations
Damage analyses and root cause determination

With our comprehensive engineering solution methods, we support you in realising projects in the most efficient way.

Mesh generation

ARTEQ GROUP creates high-quality finite element meshes. Mesh generation is a critical and complex step in numerical simulations that requires a great deal of precision and expertise. Using advanced processors, we transform your CAD data—incorporating geometric properties, material characteristics, boundary conditions, and loads—into optimized FEM meshes. These meshes are delivered as executable input sets, ensuring seamless integration into your simulation workflows.

Our meticulous approach guarantees accuracy, efficiency, and reliability, empowering your team to achieve superior results in product development and analysis.

CFD simulation

CFD calculations are used to analyze various types of flows. Depending on the application and complexity, CFD simulations can be highly detailed, as the infinite degrees of freedom in a fluid continuum must be mapped to a finite number of points in space and transformed into matrix equations using advanced mathematical methods.

Our CFD analysis services include:

Flow velocity and distribution analysis
Steady-state and transient CFD simulations
Optimal turbulence modeling (RANS, SAS, DES)
Single and multiphase flow simulations
Flow calculations for liquids (compressible media), gases (incompressible media), and complex fluid mixtures (e.g., oils)
Flow simulations with and without heat transport/temperature fields
Pressure drop calculations
Coolant flow analysis for metal processing

With our expertise in CFD simulations, we provide precise and reliable solutions tailored to your specific requirements.

FSI simulation

For some investigations, the simultaneous consideration of the structural-mechanical and fluid-mechanical becomes necessary in order to analyze the interactions and optimize the product accordingly. With the fluid interaction structure (FSI) simulation we numerically analyze the mutual influences of fluids (liquids or gases) and the structure.

Since there is currently no standardized software for this purpose, the FEM and CFD simulation environments must be coupled simply or bidirectionally in order to ensure a continuous exchange of boundary conditions and results for the calculated time step (iteration). Here, depending on the application, customized ASCII script programming may be required. FSI applications we perform include:

General fluid-solid interaction calculations
Heating by convection and/or coolant flow (fluid mechanical/thermal)

Numerical optimization

The optimization of parts, machine components, products or tools should be in the focus of every company and every research and development work, because innovation and productivity complement each other and can be realized with integrated computer-aided x-technologies (CAX) systems.

Take advantage of the know-how package we offer and benefit from the technological and economic advantages. We offer you target-oriented and competent support and implement your complex projects efficiently with modern design and simulation techniques, starting from prototypes, tool design up to the process.

Depending on the task, we are able to develop mathematical models and algorithms so that multidisciplinary tasks can be solved efficiently. In addition, we offer correspondingly specific programming of application-oriented interface solutions, so that your employees can perform calculation routines and evaluate simulation results with highly simplified software modules. Our optimization tasks include:

Parameter studies
Sensitivity analyses, robustness evaluations and reliability analyses
Optimization calculations e.g. for geometry
Robustness and reliability analyses

With our comprehensive engineering solution methods, we support you in realising projects in the most efficient way.
