More than good enough for most tasks & without having to bring your data back to base. It’s not as snappy as having everything on your local machine, but it’s streets ahead of a remote desktop connection. Or you’re connecting to a server in a datacenter on the other side of the globe. Whether you’re using it to connect a client on your laptop to a server on your workstation. Saving you the time & expense of moving simulation data around the place. In it’s simplest form you, run a graphical client on your local machine & read the data into a server somewhere else. Please don’t use ParaView via a remote desktop connection 🙏 the client-server option is your friend. If so, here are a few nuggets that I’ve picked up along the way which might be of interest… Client-Server That’s the process at a high level & it’s probably quite like yours. The exports from OpenFOAM, the image generation in pvbatch and the animation building are all done on the same instance that ran the simulation. Then I’ll use a player that supports scrubbing (like QuickTime or VLC) to play them back later as a flick book.

Most of my standard outputs are animations, so I’ll use FFmpeg to bundle the images into an MP4 movie file. I use Python scripts & the ParaView script runner (pvbatch) to produce the images. It’s not perfect but it’s a quick & easy way to start figuring out which Python commands you need.

Pro Tip: Use Trace (Tools > Start Trace) in an interactive ParaView session to record the Python commands that correspond to what you’ve just done. The exports are done in parallel, so no need to reconstruct the model & they’re lightweight to use in ParaView.īatch plots are automated using ParaView’s Python API (the simple one & even that one tests my limited Python Skillz). For the batch processing I export the assets I need – surfaces, slices, streamlines, etc. That’s the only time I read complete cases into ParaView. On the occasions that I need to dig a little deeper, I’ll fire up an interactive session & have a poke around.
Each project has its standard set of animations, output at the end of each run, for quick & easy comparison with previous results. Most of my post-pro is generated in batch mode. It’s got everything I need to do my day-to-day post-pro, it’s open-source and it plays nicely with OpenFOAM – a triple bonus. It was pretty good then & it’s come a long way since.
I’m a huge fan of ParaView, I remember stumbling across it while looking for an EnSight replacement around 12 years ago. We’re 10+ issues in now & we haven’t had any ParaView content yet – let’s remedy that, right now. If you know someone who has wanted to try ParaView but has not wanted to spend much time doing so, please let her or him know about these new ways to get up and running quickly.It’s Robin from CFD Engine, back with your weekly slice of CFD goodness. Clicking on an example visualization will load it in ParaView. Each is an example of a relatively simple but powerful visualization made possible with ParaView. Three example visualizations are also linked from the startup screen.

Clicking the link to this guide in the startup screen will open it in your local PDF viewer. The new ParaView Getting Started Guide is a brief, two-page step-by-step tutorial that shows some of the most-used features and explains fundamental concepts in ParaView. While helpful resources for learning ParaView, such as the excellent tutorial and the in-depth ParaView Guide are available and worth consulting, they require some dedicated time to fully absorb.įor new users who want to quickly see what ParaView is all about, ParaView 5.1 adds a new startup screen with some links that help ParaView rookies produce visualizations from example data in a matter of minutes. The startup screen has a link to the ParaView Getting Started Guide as well as a link to some example visualizations. Though we strive to make it easy to use, the number of capabilities can seem daunting when getting started producing high-quality visualizations with no prior ParaView experience. ParaView is a full-featured visualization and analysis application.
