Finite Element Analysis

Finite Element Analysis / Finite Element Method-simulation is one of Tech Invent’s key activities. This method is an effective tool to reduce expenses in connection with product development.

Simulation is used to optimize products in relation to material selection, material consumption, weight (topology optimization) and for strength calculations of both individual parts or complete constructions.

Furthermore, the emission of the natural frequencies and associated vibration situations can contribute to creating safety and optimum functionality in mechanical systems.

Thermal simulations can optimize energy solutions by, for example, knowing the solution’s internal and external utilization of the heat flow

Typical we use simulation programs such as:
We have access to ANSYS, SOLIDWORKS Simulation Professional, and Pro/MECHANICA for carrying out the simulations. ANSYS is out favorite tool, and we switch between APDL scripts and the Workbench method depending on the nature of the project.

What do you get?
You can always expect us to meet high requirements for reporting, documentation and compliance with relevant quality procedures.

Our engineers have the knowledge about the following concepts:

  • Topology optimization with respect to materials, material usage, weight and geometry
  • Strength calculation of anything from individual items to large structures
  • Dynamic fatigue calculation and life calculation
  • Fatigue calculation of welds and bolts
  • Linear and nonlinear stress analysis
  • Modal analysis, which is calculating the natural frequencies of different orders and corresponding vibration situations
  • Thermal simulation, which is used in cooling when mapping distribution of heat
  • Collision simulation where the durability of items are analyzed, e.g. by drop test
