Dear Gonçalo
Thank you for your answer.
I removed the square brackets but the option is still not recognized.
In fact I obtained the error message:

Error   : Unknown option '-ho_0.5,2.0,6'

Dear Andrea,

I would drop the square brackets. Your command line should perhaps read:
gmsh -2 -order 2 -optimize_ho -ho_0.5,2.0,6 geometry.geo

Dear All,
I have a problem with the high-order mesh optimizer. In particular I cannot set the optimization parameters from the command line. I need to use Gmsh from the command line because I call it from a script. If I use the GUI the algorithm works well and I can properly set the parameters (min and max jacobian values and number of layers) from the control window, but I obtain an error when I try to use the command line
option described in the documentation.
I'm working with Gmsh 2.8.4 on a 64 bit Linux machine. Maybe do I use the
wrong syntax?

The following command works but it uses the default parameters which are
not suitable for my problem:
gmsh -2 -order 2 -optimize_ho geometry.geo

The following command does not work because the last option is not
recognized:
gmsh -2 -order 2 -optimize_ho -ho_[0.5,2.0,6] geometry.geo

It seems to me that the syntax is correct...what could be the problem?

Thanks

Andrea Ferrero
