Hi Tim,

Thanks for the insight. The simulation code already dealing with vtk data 
structure. With what you mentioned, I feel more comfortable moving forward.

Thanks

Hi Simon,

I've gone through the process myself and it actually was not that painful, but 
how long it takes will depend on how familiar you are with VTK already. It's 
almost trivial if your code's data structures already use VTK. If they don't, 
then it's a matter of translating your data into the VTK data structures which 
isn't too bad in Python.

Our code is in Fortran and is a parallel, finite volume, structured, 
multi-block code. So in some ways it's a bit easier to define the data 
structures in VTK as they are structured and I don't need to worry about 
connectivity. I wrote the wrappers and interface code in less than a week with 
no prior knowledge of VTK but a very strong desire to make it work :) This was 
a few years back when the documentation on Catalyst wasn't very mature so it 
was probably harder than it would have been now.

I can't be any more specific or give you advice on how long it will take with 
your code, but it was much easier than I expected it to be when I did it.

Tim

Hello,

>From a tutorial I attended on ParaView + Catalyst, I sort of get the idea of 
all the parts involved. However, from effort point of view, on an average 
case, how many man hours would be estimated to develop a Catalyst Bridge and 
get it to work in ParaView for a homegrown discrete element method code 
written in python with some functionality in wrapped fortran, but the data 
needed for visualization is exposed to python? Just a ballpark guess (min/max 
would be nice). I want to know how big of a project I am getting myself 
into... :)

Thanks
-simon
