Hi Stefan, I also asked myself this question in the past, but didn't find a way to perform batch plotting without opening the GUI. I wanted to perform plotting when working remotely (ssh). The workaround I found was to set the $DISPLAY variable in bash
export DISPLAY=:0 or just attach to an existing "GNU screen" session for which the $DISPLAY variable is correctly set and run: xset s reset xset dpms force on gmsh batchplot.opt || die "$LINENO: gmsh error. " The first two lines are to disable the screen blanking/saver; otherwise the picture will be black. Depending on your Xorg configuration this might not be necessary. It is advisable to perform some more checks (not just || die), because the return value of gmsh can be "0" even if plotting failed. It seems your Windows workaround is very similar. -Sebastian From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, September 19, 2012 9:55 AM To: [email protected] Cc: [email protected] Subject: [Gmsh] Problem with image-generation without GUI is solved Problem with image-generation without GUI is solved The solution was to "allow the service to interact with desktop" (=windows settings) Best regards Stefan Kremer From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, September 19, 2012 9:41 AM To: [email protected] Cc: [email protected] Subject: [Gmsh] gmsh-image-generation without GUI Dear Prof. Geuzaine, i use your great tool gmsh and getdp for thermal conduction calculations. I run gmsh and getdp on a server (IIS) in command line mode (executed with PHP). Everthing works fine. If i generate a .png-Imagefile of the model with an apache-server the GUI of gmsh started on the server and the png-file was successfully build. But if i try the same process with IIS as server the image could not be generated because the server don't start the gmsh GUI. Question: Is there an alternative to generate image-files of the model in command line mode without starting the GUI? Thanks in advance. Best regards Stefan Kremer Dipl.-Phys.
