Catalyst2 break point

ParaView Support
1

Dear support.
I implemented catalystV2 adaptor for our code base.
It functions well, the only thing I noticed is that the breakpoints does not work. Only pause and continue.

I set root/catalyst/state/time as double. The
PARAVIEW_LOG_CATALYST_VERBOSITY=INFO

shows it got received.

(   2.149s) [pvbatch         ]vtkCPPythonScriptV2Help:675   INFO| .   .   } 0.000 s: DoLive
(   2.149s) [pvbatch         ]   ParaViewCatalyst.cxx:384   INFO| .   } 0.945 s: co-processing for timestep=1, time=0.000001

If I set in paraview I set catalyst connect, then breakpoint->time->0.000001 and set.

the breakpoint does not pause the simulation.

in the terminal I launched client paraview, empty lines starts to appear each time-step.

(   9.809s) [paraview        ]  vtkLiveInsituLink.cxx:409   INFO| Listening for primary Catalyst connection on `login:22222`
Accepting connection(s): login:22222

Pausing the simulation and setting the breakpoint for a later time (0.00005) and then continue also does not pause the simulation.

Where did you set a breakpoint? What debugger are you using?

They refer to catalyst breakpoints that can be set from the ParaView UI which are known to have issues. See https://gitlab.kitware.com/paraview/paraview/-/issues/21735

Yes, is there a plan to tackle this? It’s an important feature for catalyst.

it’s not planned for the moment AFAIK

FYI @nicolas.vuaille @Francois_Mazen

If this is a showstopper, you should contact Kitware to get this fixed though advanced support: https://www.kitware.com/contact/

It is not a showstopper, it’s just a pity that this issue, although known, has not been resolved yet.
