Hello,
Just to report it.....
When meshing for instance a simple box on the daily-ppa I get the following Error message in the GMSH-dialog:
Error : Unknown string option 'Solver.Extension0' Error : Unknown string option 'Solver.Extension1' Error : Unknown string option 'Solver.Extension2' Error : Unknown string option 'Solver.Extension3' Error : Unknown string option 'Solver.Extension4' Error : Unknown string option 'Solver.Extension5' Error : Unknown string option 'Solver.Extension6' Error : Unknown string option 'Solver.Extension7' Error : Unknown string option 'Solver.Extension8' Error : Unknown string option 'Solver.Extension9'

Re: Meshing .... Error : Unknown string option 'Solver.Extension0'
Which version of gmsh? Does it happen if you run gmsh with the geo and brep too?
Re: Meshing .... Error : Unknown string option 'Solver.Extension0'
We had it here too. I never had this problem. viewtopic.php?f=18&t=21147
Re: Meshing .... Error : Unknown string option 'Solver.Extension0'
I just built the latest FreeCAD source on my thinkpad with
OS: Linux Mint 17.1 Rebecca
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.10492 (Git)
Build type: Unknown
Branch: master
Hash: 58ed7c3688beb98ef89994919eddd9a4d0dd55e2
Python version: 2.7.6
Qt version: 4.8.6
Coin version: 4.0.0a
OCC version: 6.8.0.oce-0.17
which uses also a very old version of gmsh (2.8.3) coming from some outdated Ubuntu repo and I got nearly the same error.
I also tested bernds suggestion and loaded the geometry as a brep file directly into this old gmsh and I also got those messages.
This error vanishes if you download the latest gmsh 2.16.0 version from gmsh.info and use this as the binary for meshing in FreeCAD.
(See Preferences -> FEM -> GMSH -> binary path.)
I hope this helps.
Best wishes
Johannes
Edit: I checked also the ability to use recombination elements (making quads from tets) and it seems that shown quad mesh meshed with gmsh 2.8.3 is not perturbed, in contrast to the same geometry meshed with 2.16.0 (like in https://forum.freecadweb.org/viewtopic.php?f=18&t=21349)

I used the standard version 2.10.1 from Ubuntu 16.04 respository.bernd wrote:Which version of gmsh? Does it happen if you run gmsh with the geo and brep too?
I have downloaded 2.16.0 from gmsh.info, changed settings form gmsh-path and the error vanishes. Changed settings back to sytem-standard-gmsh and cant reproduce the problem. Strange!
Cound run standard-gmsh with the geo files in tmp without problems
Code: Select all
/tmp$ gmsh shape2mesh.geo -format unv

@Bernd: which version of gmsh do you use?
