With our experience, competences and expertise we support you in your tasks and solve them with numerical techniques. For structural-mechanical analyses such as strength calculations, thermo-mechanical load simulation and analyses, the Finite Element Method (FEM) simulation is usually used and for fluid-mechanical investigations the Computational Fluid Dynamics (CFD) simulation. If the interactions between the mechanics and the flow are to be investigated, fluid-structure interaction (FSI) simulation is used. In any case, simulation solutions have great potential in the product development process. Compared to otherwise conventional experimental analyses, they not only save you costs and time, but probably also one or two nasty surprises. Because only those who know enough about the product behavior early on are able to apply this knowledge effectively and thus steer the further process on the right track.
Benefit from our many years of simulation experience with which we have already successfully completed numerous projects. With us as a competent partner for engineering services, we offer you active support from the idea to the finished product and provide solutions for the complete development process.
Finite element method (FEM) simulation describes physical phenomena by means of partial, location- and time-dependent differential equations and is the most widely used method for calculating complex structures in numerous disciplines. In mechanical engineering, it is mainly used for strength calculations, mechanical and thermomechanical load simulations. Continuum mechanical relationships can be described and the overall behavior can be efficiently calculated with appropriate algorithms. Benefit from our many years of experience and take advantage of the benefits we offer in the context of holistic product development in various areas. This includes for example:
The generation of finite element structures is very complex and requires a correspondingly long processing time. Based on CAD data of geometric properties, material properties, boundary conditions and loads, we create FEM meshes for your project with powerful processors. We hand these over to our customers as an executable input set.
Computational Fluid Dynamics (CFD) calculations can be used to analyze any type of flow related to fluid-fluid, fluid-solid or fluid-gas interactions. Depending on the field of application and complexity, the numerical CFD simulations can be very extensive, since infinite degrees of freedom of the fluid continuum have to be mapped to finitely many points in space and converted into matrix equations using appropriate mathematical methods. These discretizations (meshing/grids) are implemented using CFD software and the physical laws are solved in terms of complex systems of partial equations using sophisticated CFD solvers.
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:
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;
Visualization of the transient cooling lubricant supply for a twist drill with the Smoothed Particle Hydrodynamics (SPH) method to show the ability of the dynamic development of different flank shapes.
