CADFEM ANSYS extension for combining of injection molding simulation with ANSYS Workbench

Two worlds, one goal

In the development of components made of short fiber-reinforced plastics, two types of simulation play a central role. While an injection molding simulation maps the manufacturing process, a strength calculation establishes the structural mechanics behavior of the component under analysis.

Connecting the results of these two different analyses with each other, in the interest of optimum product quality, has long been considered extremely complex. This is where the MoldSim inside ANSYS solution developed by CADFEM comes in: It allows the direct import of pertinent information from the injection molding simulation into the structural mechanics calculation in ANSYS Workbench.


  • complete integration of the process from the import of the injection molding geometry data through to the evaluation of the results in ANSYS
  • quick import of the fiber orientation and distortion stresses into ANSYS
  • homogenization of the results from the mechanical FE mesh

Technical Informations

System requirement:

  • ANSYS Workbench up to version 16
  • Support of Autodesk Simulation Moldflow Insight, Moldex3D and Simpoe
  • On request enlargement on other injection molding tools

The direct path from injection molding to structural mechanics

Short fiber-reinforced plastics are used in numerous industries such as consumer goods, automotive, aerospace, shipbuilding, medical engineering, electronics, and electrical industry.

Integrating the results of the injection molding process into the structural mechanics simulation provides a comprehensive analysis of the final production part performance. Until now, this has only been possible with a great deal of effort. Consequently, CADFEM developed MoldSim inside ANSYS to seamlessly integrate the results of an injection molding simulation into the FEM simulation environment of ANSYS Workbench.


Optimum plastic components

MoldSim integration allows the user to incorporate the effects on structural material properties of relevant injection molding attributes such as distortion stress, fiber orientation, and fiber content into the strength calculation by ANSYS Workbench.

Therefore, local and global effects can be examined for their contribution to the structural behavior of the production part. The completely integrated workflow, from the injection molding simulation by MoldSim linked to a FEM analysis with ANSYS, offers an efficient and complete process simulation that delivers significant design improvements.
