Is it possible to display several views of the main graphics window at the same time when running a simulation ?

Yes, displaying several views at the same time is possible only through network graphics (which works on local machine too). Details about network graphics can be found in the manual section Graphics/NetWorkGraphics.Following setup is recommended in the ‘Wobble the Gomboc’ window, in section ‘General’:

Network client needs to be opened with command line (or batch file shortcut): Gomboc.exe –graphics-client=ws://127.0.0.1:10000

Then, graphics items can be customized on each different view:

To go further: When working with several views, different overlays layouts can be displayed on each of the views. This can be achieved by defining multiple overlays layouts and use the desired layout in client using command line parameters or selecting the appropriate layout in ‘Graphics -> Overlays Layouts”.

Several layouts can be defined by using `Graphics.OverlaysLayouts.MyLayoutName1` instead of using `Graphics.Layouts` in the bic file, The new layout `MyLayoutName1` will then appear in the menu ‘Graphics -> Overlay Layouts’. For instance, in the Overlays BIC file below, 2 layouts are defined ‘LayoutEmpty’ and ‘LayoutAuto’:

Note that when defining multiple versions of overlays layout, a default overlays layout needs to be specified. This is done using the ‘Graphics.DefaultOverlaysLayout’ property:

I am trying to display the simulation on two different windows using the graphics server /client setup described above, but this leads to an increase in simulation time:

– one window: simulation time 20.84s, real time 12.30s, 1042 steps (84.7 steps/sec) ==> 1.6 times slower,
– two windows: simulation time 6.10s, real time 29.89s, 305 steps (10.2 steps/sec) ==> 5 times slower,

There is also this error showing up at each time step: Error | GraphicsServer | Error writing UDP packet (type updateGeoResPosAndTan, size 86516).

How I can solve this simulation time issue?
It looks like your UDP datagram is too big (maximum is 60’000 bytes). The only reason you can get to such a big datagram for graphics is probably when visualizing the deflected foil. I think this will disappear if you just visualize the standard undeflected foil.
