I used Netgen successfully in 2013, using system calls from fortran code.
I am trying to use it again. I installed the package on ubuntu 16.04 using the installers. I verified the install by using the GUI to mesh a few of the supplied geo files. (I have since since upgraded to ubuntu 17.04).
My old codes/scripts don’t work for command line execution (system calls). I can get netgen to read files and create output files - at least .vol and .mesh (neutral) files. But no meshing occurs.
For example, one of the commands I tried is (with out.vol being a .vol file generated by netgen):
netgen -batchmode -inputmeshfile=out.vol -meshfile=new_out.mesh -meshfiletype=“Neutral Format”
This (no meshing) also occurs when trying use the GUI to mesh the .vol file. Nothing happens. The input object appears, but attempts to mesh (by pressing Generate Mesh) doesn’t do anything.
Side note: I got a note saying that I should make sure ng.tcl is in NETGENDIR: Should that be ngsolve.tcl? I don’t have a ng.tcl on my system.
Thanks in advance,
