Build it with MPI, Python and Catalyst enabled (Catalyst should be enabled by default but MPI and Python need to be explicitly turned on). The Catalyst editions are meant to be subsets of ParaView that get rid of specific functionality that may not be needed for certain simulation runs. This helps for decreasing executable size but can make it slightly more confusing. See <a href="http://www.kitware.com/blog/home/post/606">http://www.kitware.com/blog/home/post/606</a> for an explanation on that. At one time I tested the Catalyst examples with several of the editions but haven't tried it recently so it's possible that something broke.<o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>As for the Connect to Catalyst option in the ParaView GUI, I've never tested that with any of the Catalyst editions so it's possible that they don't work with the "live in situ" connection. Again, using a full ParaView 4.1 build should work here though. We're in the process of improving the line in situ connection right now for a project that ends in August. This should vastly improve the usability of this. <o:p></o:p></p></div><p class=MsoNormal>I'm not sure I answered all of your questions but my goal was more to get you past some issues and then we can help you focus on the other parts that come up as well as making everything work more efficiently together.<br><br>Regards,<br>Andy<o:p></o:p></p></div><div><p class=MsoNormal style='margin-bottom:12.0pt'><o:p> </o:p></p><div><p class=MsoNormal>On Fri, Jun 6, 2014 at 5:18 AM, Praveen Narayanan <<a href="mailto:praveenn@nvidia.com" target="_blank">praveenn@nvidia.com</a>> wrote:<o:p></o:p></p><div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>Greetings<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I am examining the example code for catalyst from Andy Bauer’s git repository (<a href="https://github.com/acbauer/CatalystExampleCode" target="_blank">https://github.com/acbauer/CatalystExampleCode</a>).<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>I am trying to learn about the catalyst workflow before using it in my own in situ examples. <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>To this end, I built catalyst from the nightly samples in the paraview download page (<a href="http://www.paraview.org/download/" target="_blank">http://www.paraview.org/download/</a>).
