[Paraview] viewing Gadget2 simulations

[George Zagaris]

Hi Tim,

I was able to open the dataset you provided. Here are a couple of
suggestions:

(1) Make sure to uncheck the "Cosmo Format" checkbox -- this will ensure
that the underlying reader will read in the data as a Gadget file.

(2) Set "rL", i.e., the box-size of the simulation data accordingly

(3) Set overlap to 0 -- This parameter creates ghost zones between
inter-processor and periodic boundaries which you may need if you are
running this in parallel, depending on what you want to do after you read
in the data.

Attached is an image of what the output looks like when I do the above with
rL=100.

Best,
George
