Hello,
No, we do not include MEDCoupling in the Windows version.
Regarding the Windows version, see this thread: https://discourse.simvia-app.fr/t/help-needed-for-windows-build/1314/1 I may have a solution for the graphical part (I should test it within a month), but for the non-graphical part, the solution would be either to use the Windows subsystem for Linux (which already works well today, and in which MEDCoupling should work) or Docker (with which we have experimented but not built a complete package so far).
In any case, the use of MEDCoupling is limited in Code_Saturne version 5.0 (it is better to use 5.2 or 5.3). I might be able to write a subroutine for 5.0 that would do what you need (and work on the Windows build), but probably not before a few weeks (schedule being already very busy for this month).
Best regards,
Yvan
