Hi, I am new to OpenFoam, I am trying to import a .msh generated in gmsh as in the tutorials below:

In gmsh everything is ok (same as in tutorials), but when I try to import the msh file into OpenFoam using gmshToFoam, I get the following error:
(any help is appreciated, thx!)

Hi Mihai,

What are you typing into the terminal exactly?

And what is the location of your .msh files in relation to your case directories?

The command should read something like:

 gmshToFoam yourMesh.msh -case yourCase

Hi Everyone,

I'm facing a similar problem! The thing is that gmsh generates a 3Dmesh on its interface but when I save it to a.msh file something goes wrong.
This is the error I'm getting:

Perhaps you have not exported the 3D elements?

And this is my rather long .geo file

Figured out my silly mistake.

I just had to define a Physical Volume for my 3d mesh as follows:

Physical Volume("fluid")={all individually defined,..., .... , ....., volumes};
