Structural
Mechanics

Unlock the full potential of your structures with our expert structural mechanics simulation services. We specialize in analyzing the behavior of structures under various loads to optimize design and dimensioning. Utilizing advanced Finite Element Methods (FEM), we calculate complex components and assemblies with precision. Our FEM models are constructed through solid body modeling and are subjected to external mechanical and thermal loads.

What sets us apart is our ability to translate complex systems into suitable simulation models. This includes the demarcation from the environment, accurate modeling of storage and restraints, interfaces, contacts, and material properties. We focus on key variables such as deformations, stresses, strains, force flow, reaction forces, contact stiffness, and thermal effects like heat transfer and thermal expansion.

Structural
Dynamics

Experience unparalleled insights into your structures' dynamic behavior with our structural dynamics analysis services. We delve into the movement of structures resulting from time-dependent loads, focusing on the vibration and dynamic behavior of complex components, assemblies, and systems. Our experts identify and correct undesirable structural vibrations, quickly pinpointing critical issues.Every structure has its own natural frequencies and modes, which can lead to resonance and potential functional impairments. We perform comprehensive simulations, including modal analyses, shock and vibration tests, as well as drop, impact, and crash tests. Additionally, we specialize in simulating the rigid body movement of moving assemblies and systems.

Fluid
Mechanics

Optimize your designs with our cutting-edge Computational Fluid Dynamics (CFD) services. We accurately predict the flow behavior of liquids and gases, making movements in stationary or streaming media visible and understandable. Given the complexity and non-linear nature of real-world problems, we employ network and particle-based methods like CFD and SPH to solve almost any challenge. Our services cover complex systems, machines, and components involving flow, including multiphase flows, phase transitions, and moving components. We provide valuable results such as velocity and pressure distributions, streamlines, pressure losses, turbulence, and heat transfer. These insights contribute to product understanding, design optimization, early detection of critical zones, and uniform distribution.
