| - | These are also available as modules, please use ''module avail''. There are two modules for each of Paraview-5.3.0, 5.4.1, 5.5.0 and 5.6.0, the second one being appended with ''-VNC''. Use this for running Paraview on a viz node. Please refer to the [[http://www.paraview.org|Paraview web site]] for instructions on using Paraview. For interactive graphics on a virtual desktop, an OpenGL-enabled environment will be required, therefore refer to the page on [[howto:remote_viz|Remote Visualization]] for instructions on setting up a connection to the visualization node, and running Paraview with the VirtualGL wrapper. Paraview is an extremely versatile post-processor, and can be used as the primary visualization tool for a very wide range of applications and file formats, including OpenFOAM, MFix, SU2 and many others. | + | These are also available as modules, please use ''module avail''.

| - | For many small to moderate visualization tasks, the user may wish to run the Paraview client directly on the cluster, in a [[howto:remote_viz|VNC session]]. This can be done easily on one of the visualization nodes chpcviz1 or chpclic1. However, due to high levels of use on these nodes, or a demanding data set, the user may prefer to use a VNC session on a compute node. This process is [[http://wiki.chpc.ac.za/howto:remote_viz?&#getting_a_virtual_desktop_on_a_compute_node|documented and straightforward]]. However, this relies on persuading the Paraview client to work properly with the Mesa software rendering libraries. and this procedure varies between the various Paraview versions. | + | For many small to moderate visualization tasks, the user may wish to run the Paraview client directly on the cluster, in a [[howto:remote_viz|VNC session]].

However, this relies on persuading the Paraview client to work properly with the Mesa software rendering libraries. and this procedure fails with the later Paraview versions. The problem is an incompatibility between Mesa, VNC and the Qt-5 library. Older versions that rely on Qt-4 work extremely well on a compute node. The following versions have been tested. |
