gmshToFoam on openfoam windows version of OpenFOAM v1812?
 

I'm new to OpenFoam and struggling. Sorry for stupid questions.

I'm working on flutter of 2, 3D wing and having some problems.

First, I installed OpenFoam in Linux using Docker and I have no idea what so ever where my files are stored and how to use Docker. So I dumped it and went to compiling version. It works but whenever I close terminal I need to set it up again which was frustrating. Then I went to windows version and cannot get gmshToFoam to work properly. I keep on getting

--> FOAM FATAL IO ERROR:
Bad token - could not get word

When I know it should work OK since I checked in Linux version and windows version supplied by "CFD support".
Does anybody know how to fix it?

Also, I installed OpenFOAM supplied by "CFD support" and it works fabulously until I wished to use overpimpleDyMFoam.
Looks like overpimpleDyMFoam function doesn't exist at all in "CFD support" version? Can anyone confirm that?

Thank you in advance for answering my stupid questions.
