Production Engineering Work Group


The production engineering group at CATS is concerned with modelling, simulation, and optimization related to manufacturing processes. Our main focus lies on melt-based processes, such as plastics profile extrusion, high-pressure die casting, and injection moulding.

Our main modelling tasks are:

  • generalized Newtonian and viscoelastic material models

  • solidification of plastics and metal melts

  • polymerization reactions

Our numerical methods include:

  • methods for multi-phase flow

  • stabilization methods

  • methods for deforming meshes

  • spline-based finite element methods

Our optimization tasks are:

  • development of objective functions
  • geometry description
  • choice of appropriate optimization algorithms
  • automatic differentiation
