COMSOL has the best multiphysical simulation capabilities in my experience. Technical support from Elisa at TECHNIC as well as the engineers at COMSOL has been great.
COMSOL is an important part of our research in plasma physics. We use it in the design of plasma systems and it helps us to obtain a greater understanding of the underlying physics. We have always valued the quick support from TECHNIC and COMSOL and it has been a pleasure to work with them.
Comsol has become a valuable part of our design and decision making process. The exceptional flexibility and access to the physics and solvers in Comsol has allowed us to have deeper understanding on thermomechanical solutions. Technic and Comsol have always been quick and helpful to resolve any issues and provide helpful advice on their products.
At Scion we use COMSOL Multiphysics to understand energy processes, such as the interplay of non-linear solid mechanics and heat & mass transfer during biomass compaction, to design new or more efficient processes.
We use COMSOL Multiphysics to design the customised muffler. With it, we can simulate the insertion loss at different spectrum with different muffler designs.
LiveLink™ for PTC® Creo® Parametric™ is an add-on to COMSOL Multiphysics that seamlessly links 3D designs in the PTC® Creo® Parametric™ CAD system to COMSOL Multiphysics model geometries for simulation. Creo Parametric is an industry standard for 3D CAD and includes a comprehensive set of tools for maximum flexibility and productivity. COMSOL Multiphysics with LiveLink™ for PTC® Creo® Parametric™ enables you to benefit from the advanced capabilities in Creo Parametric to produce state-of-the-art designs and then integrate them into a COMSOL Multiphysics model for analysis and optimisation.
LiveLink™ for PTC® Creo® Parametric™ updates your design workflow to include multiphysics simulation capabilities that allow you to better understand how your product or design performs in the intended operating environment. Models in COMSOL Multiphysics can include essentially any relevant physical effects and their interactions to accurately simulate your design. LiveLink™ for PTC® Creo® Parametric™ includes features to prepare CAD geometries for simulation and to update designs during the simulation process for use with automated parametric sweeps or optimisation studies.
LiveLink™ for PTC® Creo® Parametric™ synchronises your designs in Creo Parametric with your COMSOL Multiphysics models and automatically propagates design updates while running the programs concurrently. CAD models do not have to be manually exported or imported into COMSOL Multiphysics with each change. Parameters, including part dimensions or placement, defined in Creo Parametric can be iteratively accessed from COMSOL Multiphysics enabling simulations with parametric sweeps and optimisation studies. Through direct synchronisation, LiveLink™ for PTC® Creo® Parametric™ retains the associated physics definitions on model domains and boundaries even when features are updated or added to a design.
LiveLink™ for PTC® Creo® Parametric™ includes the capability to automatically detect and repair geometric anomalies in a design and to perform defeaturing operations to prepare a CAD model for simulation. Predefined tolerances are used during the import of a CAD model to automatically identify problems and make sure that the imported solids or surfaces are correctly defined. Gap healing is also automatic during import to ensure that a solid is produced for meshing and simulation. Small, often insignificant, details or anomalies in a geometry create areas with very dense meshes making simulations less efficient. After a successful import, you can further defeature the geometry by identifying these fine details based on tolerance settings. You can then remove all, or selected, items that meet the specified criteria. Features that you can remove in this manner include slivers, small faces, or edges, and design elements such as fillets.
Virtual geometry operations in COMSOL Multiphysics provide an additional means to reduce the computational complexity in a simulation caused by dense meshes. A virtual geometry is created by selecting small features in a design that you want ignored by the meshing tools. While you are defeaturing a design you are removing small features, and the geometry algorithm covers the resulting holes by stretching or shrinking the surrounding faces or edges. This operation inevitably modifies the local curvature of the geometry object. By using virtual geometry operations you can preserve the curvature, since the surfaces and edges are not removed or modified, only hidden. The simulation mesh on a virtual geometry reduces the required computational resources and is still based on the original design, even in the slightest detail, for those simulation applications that demand this.
Instead of directly linking or synchronising with a COMSOL Multiphysics model, CAD files can be imported and exported in a range of formats. Using LiveLink™ for PTC® Creo® Parametric™, you can import 3D CAD files in the Creo Parametric formats (.prt, .asm), as well as in one of the widely used Parasolid®, ACIS®, STEP, and IGES formats. In addition, you can import the native files of the Inventor®, and SOLIDWORKS® CAD systems. The optional File Import for CATIA® V5 provides support for importing the native file format for this system. Imported 3D CAD models are converted to Parasolid geometries that can be further modified in the COMSOL Multiphysics environment. Modifications to a Parasolid geometry in COMSOL Multiphysics can include Boolean geometry operations or the addition of fluid domains to a model that otherwise consists of solid parts. When making changes to imported geometry, or even creating your own additions to illustrate a concept, you can always be sure that you can share your work by exporting modified designs in the IGES, ACIS, Parasolid, or ACIS file formats for import into other tools.
