How to save mesh in .msh ASCII 2 format from Gmsh Python api?

I need to save my mesh (created with gmsh python api) in .msh ASCII version 2 format in order to use the command dolfin-convert and import the mesh inside Fenics.

From the tutorials, to save the mesh I should use the command:

gmsh.write("filename.msh")

however, if i try to convert the mesh in .xml file (in order to use it in fenics) with the command:

dolfin-convert filenam.msh filename.xml

it returns an error:

ValueError: invalid literal for int() with base 10: '4 25240 1 25240\n'

If I save manually the mesh in .msh ASCII 2 format everything works well.

I need an automated process so I can't save it manually every time, how can i use the Python api to save the mesh in the correct way?

Thanks in advance!

Try this:

gmsh.option.setNumber("Mesh.MshFileVersion",2.2)   
gmsh.write("filename.msh")
