[Paraview] Input files

[Samuel Key]

Doina,


Welcome to ParaView.


Here is the URL for the user's guide: 
https://www.paraview.org/paraview-guide/

(In the second paragraph "(CE)" click on the first blue here.)


First comment, ParaView is not a mesh generator. (It does have a number 
of displayable graphics objects, for example, a sphere. They are are 
ordinarily used for testing and/or for demonstration of ParaView's 
filters, et cetera.


Second, one needs to select an input format that ParaView understands 
and use that format to "describe" your simulation results, that is, 
describe your mesh, the datum set that resides at Points and the datum 
set that resides in the Cells.

The simplest (well documented) format is the VTK-Classic format, an 
all-ASCII format (see attached document). There is a caution when using 
this format guide, namely, the guide is concise and complete, but the 
information is stated only once and not necessarily where you would 
expect to find it.  One more caution --  The VTK READER in ParaView was 
written by a C-language programmer, and the input array-location 
information requested is in offsets. A value in the array A(1:100) at 
the first location is at "0" and the item at the end of the array is at 
location "99"

Just about all useful formats will have the information needed by the 
VTK-Classic format and once you have mastered this format, the other 
formats will make more sense.

Hope this helps,
