create and save snapshots of the simulation without displaying on screen

Hi,

https://yade-dem.org/doc/yade.wrapper.html#yade.wrapper.SnapshotEngine might be what you need.

Jerome

but i need to display the GLView first to save it with that engine.

Hi José,

please be more specific why you need to save snapshots without displaying
images.

A workaround (the applicability depends on the reason why not to display
images) is to export everything to vtk files and then use paraview [1,2]
(or some other software [3]) to create the pictures in "offscreen mode".
cheers
Jan

i need to save snapshots to generate a video simulation, I will review what you sent me, thank you!

Hi José,
why you need snapshots is clear :-) I wanted to make clear why you need
snapshots without displaying images (is it anoying? Do you you run the
simulations on cluster without GUI? ....?)
Thanks for the information

yes, because i will use a cluster without GUI.

thanks you for your help as always!

Or you can just save the vtk files on the cluster, then copy them and
create video "manually" using standard paraview...
