[Paraview] How to simply "Reload" a data file

[Biddiscombe, John A.]

If either of you are using hdf5 (xdmf for example) you could try our dsm reader. Paraview creates a memory buffer which is used instead of the filesystem by your client application which generates data and writes it to hdf5, it is routed to the dsm inside paraview which updates automatically when the writer closes the file.

I've cleaned it up a it and got it mostly working with paraview 4.0 and will make a 'release' soon. The main problem is that when the app writing data, or paraview shut down, it isn't very clean disconnecting unless they happen in the right order. If one shuts down unexpectedly, or is closed without isconnecting, problems can arise. Apart from that it is quite stable.

I'll post a video and a link soon.

An alternative is to just add a reload button which calls modified and make the filename widget visible - I've just seen a post from Sebastien that does it for you whilst I was typing.

I would love to know how to do this if it is possible. For one of our workflows, a periodic checking if an input file has changed and reloading it at a specified time interval would be even better.

Thanks,
Cory
