[Paraview] Catalyst and In situ Visualization

[Amit Goel]

Dear Paraview Users and Gurus

I am new to paraview and attempting the following task.. please let me know if my understanding is correct.

I have a simulation that runs and spits out H5Part file, having location of say 1000 particles with locations that I can see with paraview. If I use catalyst c++ libraries and embed code in my simulation code then I can send that output to paraview directly. so the final simulation will look like this:

Simulation Code —> “Send to Paraview Catalyst" Code  -> Paraview -> Image or Video output.

I believe that 

1. alongwith send to paraview catalyst code, I can also send to H5Part file. but creating H5part files is no more needed if I am sending directly to paraview and creating images.

2. While paraview in above arrangement is working on creating visualization, in the background, I can connect to that paraview instance using paraview client and see whats going on with visualization.

Am I correct in my understanding of Catalyst+Paraview in above description ? If yes then I will try it in next coming days and seek your help where I get stuck.

Regards

Amit
