SimPARTIX® - Particle-based simulations for process optimization.

SimPARTIX® stands for our competence in modeling the mechanics of materials and fluids using mesh-free methods. 

SimPARTIX® is also an innovative and powerful simulation tool developed at the Fraunhofer IWM.

Based on physical models, SimPARTIX® is used to investigate various materials in manufacturing processes and in service. This typically generates a large amount of data on the dynamical material behavior. By means of detailed analyses and visualizations of the data we provide in-depth insights into the fundamental dynamics of your processes. SimPARTIX® can therefore help you to grasp a full understanding of your applications and yield design specific optimization measures.

Grinding the hardest to reach places within a component

It’s long established that flow grinding can be utilized to grind and polish the inner surfaces of components such as corners and drill holes: a fluid containing grinding particles is pumped through the component. However, flow dead zones can arise when a component has a complex form. In these cases, the flow stagnates at a specific spot, which results in the grinding process being ineffective in that area. To address this...
