Hi Pierre,
Sorry for the confusion. I thought there was a "sticky" post that described this, but I see there is not one. (A "sticky" post is one that stays at the top of page 1. I will create one that links to the relevant article.)
The short answer is that In-CAD 2018.0 is the last version that will work with SolidWorks. The long answer is described in the article "Important Information for SOLIDWORKS Customers using Autodesk Nastran In-CAD".
But as explained in the article, you can use Inventor (part of the collection) to read the SolidWorks model and use the latest version of In-CAD. Here is the text from the article that describes that functionality:
Can I continue using SOLIDWORKS for modeling and use Inventor/Nastran In-CAD for simulation?
Yes. Inventor 2016 and later versions include an import technology called AnyCAD that allows you to reference SolidWorks parts or assemblies into Inventor. Unlike a traditional translation these references are associative. Whenever the SolidWorks file changes, the updates are accounted for inside Inventor and allow simulations to be re-run within Nastran In-CAD. See this page for more on AnyCAD.
