Conversion from Topsolid to COMSOL Multiphysics is not supported yet :(

TopSolid is a completely integrated CAD/CAM software which was created by the French company Missler Software. It is based on the geometric kernel ParaSolid. As it is fully integrated, it allows users to design and manufacture parts using the same software. There is a wide range of Topsolid industry solutions: from the more general, mechanically oriented (TopSolid’Design) to specific solutions.

Actually, there is a whole line of CAM products: mechanical machining (TopSolid’Cam), sheet metal (TopSolid’Sheetmetal), wood (TopSolid’WoodCam), wire electroerosion (TopSolid’Wire). TopSolid also incorporates additional modules: a 2D draft module (TopSolid’Draft) and a structural computation one (TopSolid’Fea).

TopSolid'Cam, one of the main products of Topsolid, manages multi axis machining such as 5 axis machining, mill turn operations, twin Spindle and twin turret technology.

TopSolid 7 is claimed to simplify the design and modification of large assemblies in an organized and structured environment.

COMSOL Multiphysics® is a general-purpose simulation software for modeling designs, devices, and processes in all fields of engineering, manufacturing, and scientific research. In addition to using multiphysics modeling for your own projects, you can also turn your models into simulation applications and digital twins for use by other design teams, manufacturing departments, test labs, customers, and more.

The platform product can be used on its own or expanded with functionality from any combination of add-on modules for simulating electromagnetics, structural mechanics, acoustics, fluid flow, heat transfer, and chemical engineering. The add-on modules and LiveLink™ products connect seamlessly for a modeling workflow that remains the same regardless of what you are modeling.
