[Giuseppe Di Giulio]

Sorry
I probably forgot the Par_file in my previous message

> ​​​Dear SpecFem developers
>
> I am using Specfem2D 7.0 with an external mesh (built by gmsh) aimed at
> investigating the topographic effect.
>
> My will is to fix the position of the receivers on the topographyc surface.
>
> My understanding is that the parameter "enreg_surf_same_vertical" in the
> Par_file cannot be "true" with an external mesh.
>
> I try to set multiple receiver lines in the Par file where (xdeb,zdeb) are
> the coordinates of my receivers. The receiver lines (nreceiversets
> parameter) are fixed to the same number of receivers, and  nrec is equal to
> 1 for each receiver line (and for this I do not care of xfin and zfin; see
> the end of message).
>
> Unfortunately it does not work, the error message after the run of
> xmeshfem2D is
>
> "At line 326 of file ../shared/read_value_parameters.f90
> Fortran runtime error: Bad real number in item 1 of list input"
>
> Any suggestion to place receivers on topographic surface with an external
> 2D mesh is welcome.

> The Par_file and my mesh are available as attach
