<p class="MsoNormal" style="margin-bottom:12pt">Hi John,</p><div><div><br>
<br>
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.
<u></u><u></u></div></div><p></p>
</div><div><div>
<p class="MsoNormal" style="margin-bottom:12pt">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.<u></u><u></u></p>

<p class="MsoNormal">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
