[Paraview] Catalyst question

[Biddiscombe, John A.]

Andy

Thanks for the info, great news that the live stuff is ongoing. My current test uses cxx only, so I didn’t play with the python pipelines and hadn’t noticed the live viz option. I will experiment and get back to you.

I saw a bunch of questions recently about doing GPU based stuff inside catalyst and it is my aim to get my cuda/piston based renderers working in-situ. I’ll let you know how I get on.
If there are commits on branches you think I might want to test, please say.

thanks again

JB

Hi John,

This live capability is now available and recently has been cleaned up quite a bit. There are still a couple more small changes that are waiting a code review process before they go into the master branch. The user's guide needs an update for a bunch of new information (live, catalyst editions, zero-copy arrays) that's important for Catalyst. We're also doing some preliminary testing with a newly developed ADIOS writer for better IO performance as well.
Getting back to the live viz stuff, when you create a Catalyst Python script and export it using the wizard you'll have the option to enable live viz (it's the same wizard page as the screenshot output specification). Then, while your simulation is running use the Catalyst->Connect option to connect. There are two tests (pv.CatalystLiveSetBreakpoint and pvcs.CatalystLiveSetBreakpoint) that demonstrate the newly implemented live functionality which now includes the option to set a breakpoint in the simulation.
If you get a chance to try it out, let me know what you think.

Andy

Dear Catalyst people

I dragged out an old simulation demo I created some time ago and got it working with paraview/catalyst from git master branch - my plan was to test a live visualization of the simulation with the paraview GUI connected to the simulation. I had thought this capability was now possible, but I have not been following development closely and it looks like I was mistaken.

Is it possible to visualize the simulation live - rather than just generate images (which works fine). (I had a quick skim through the user manual, but didn’t see this feature mentioned).

Thanks

JB
