SimpaTec GmbH (Aachen, Germany) has released Moldex3D R14 to improve the speed, robustness and reliability of simulation of injection molding and resin transfer molding (RTM) processes. The new Moldex3D Boundary Layer Mesh (BLM) generator allows for the use of fewer meshing elements, which reduces the meshing time while keeping up the maximum wall thickness resolution. Another feature is Designer BLM, the auto repair function that is said to significantly reduce the effort and time needed for mesh generation. Common mesh defects such as free edges, T-connect edges and overlapping elements can now be automatically detected and fixed, thereby speeding up and simplifying the meshing process. Development activities related to release R14 have also focused on increasing the accuracy of fiber prediction. By using a patented fiber model, the new module Fiber 2.0 visualizes the 3D fiber orientation of short and long fiber-reinforced plastics and platy fillers. For RTM, Moldex3D R14 employs true 3D numerical technology that can reportedly capture the full geometric details to accurately simulate the resin’s in-mold flow behavior. This allows the user to rapidly evaluate and optimize design and process parameters, such as resin flow pattern and venting locations.
