Synchronize Design Updates between COMSOL Multiphysics® and PTC® Pro/ENGINEER®
LiveLink™ for PTC® Pro/ENGINEER® provides a bidirectional interface between your designs in Pro/ENGINEER and the corresponding COMSOL model geometry. Direct synchronization ensures that design updates propagate in both COMSOL Multiphysics and Pro/ENGINEER while preserving geometry associations. Geometric entities, such as edges and faces, in the COMSOL model geometry remain associated with the corresponding features in your CAD design so that physics definitions and mesh settings are preserved throughout the revision process. You can manually synchronize the design geometry between Pro/ENGINEER and the COMSOL environment when running both programs concurrently. Synchronization is automatic with parametric sweeps, or when running optimization studies using the optional Optimization Module.
CAD parameters in Pro/ENGINEER, such as the placement or length of a feature, can be directly accessed and modified by COMSOL Multiphysics. Optimization studies and parametric sweeps can be implemented in the COMSOL environment with recurrent access to CAD design parameters. When an optimization goal is achieved by varying the value of a parameter used for simulation, the final optimized value can be written back to the CAD file.
Geometry Repair Process Ensures Efficient Simulations
LiveLink™ for PTC® Pro/ENGINEER® includes tools to prepare your CAD geometry for meshing and analysis. The detection, removal, and repair of geometric anomalies is automatic when you import a design from a CAD file into COMSOL Multiphysics for simulation. Predefined tolerances are used as criteria for the removal and repair process. Small features remaining in a geometry after import can be removed at your discretion to reduce the complexity of the mesh required to simulate your design. The defeaturing tools in this LiveLink™ product can detect features such as small edges, faces, slivers, and fillets that will make your simulations less efficient. Features can be removed from the geometry using the defeaturing tools in COMSOL Multiphysics, or they can be deactivated in Pro/ENGINEER where you have access to the history of the CAD design.
Instead of removing geometric features directly from your design, you can use virtual geometry operations to omit them from your simulations in COMSOL Multiphysics. Virtual geometries are beneficial because they preserve the original surface curvature of your design while reducing the complexity of the mesh for simulation. You create a virtual geometry by selecting features you do not want meshed and included in your simulation. Using this feature enables you to reduce the required computational resources and make your simulations more efficient.
