Trame + Catalyst

trame-catalyst is a trame application for live-monitoring a running simulation connected through ParaView Catalyst, an in-situ analysis framework that avoids the I/O bottleneck of writing every time step to disk. Since it's a web app using remote rendering, you can watch the simulation from any device, with no client-side installation and no need for a powerful local GPU. See the announcement blog post for a walkthrough.
