SOLIDWORKS design parameters can be iteratively accessed and updated via COMSOL Multiphysics, facilitating design parameter optimization studies and parametric sweeps to evaluate the effects of properties such as the diameter of a hole or thickness of a component in your design. Design parameters that are controlled by relations in the SOLIDWORKS design can still be accessed in a read-only way and used when setting up a simulation, such as when defining boundary conditions or mesh element size settings.

Selections, which are defined on the CAD design inside SOLIDWORKS, can greatly reduce the time it takes to set up the simulation, for example, by automatically collecting all domains with the same material properties into one easily accessible selection. Selections also come in handy when you want to make sure that the physics settings remain attached to the correct domains and boundaries as the topology of the geometry changes while running a parametric sweep or optimization study.
FreeCAD is a parametric 3D modeler made primarily to design real-life objects of any size. It is easy to modify designs using the model history and changing the parameters. 2ff7e9595c
