This is how the result (without the monkey head, which we will insert in Blender later) looks like in ParaView: Our scene in ParaView – a few streamlines with the tube filter applied. We choose to color the streamlines by the magnitude of the velocity. A spherical source for streamlines is set in front of the monkey head and the “Tube” filter applied to the streamlines to give them some thickness – that looks a lot nicer. We are going to visualize the streamlines around the head using ParaView, employing the Plugin that is shipped with FLEXI. You need to create the actual visualization with the post-processing tool of your choice – it’s fine as long as a suitable output is provided (more on that in a second). The parameters of the simulation where set up in such a way that we achieve a Mach number of 0.2 and a Reynolds number of several hundred, which leads to a laminar but non-stationary flow in the wake of the head.Īs already mentioned, Blender is not a post-processing software. The actual hexahedral mesh around the head was then created using Hexpress. You probably need to clean up the mesh a bit, make sure it’s one continuous mesh (by default the eye-sockets are separate from the main part of the head) and that there are no double vertices. To generate the mesh, we first exported the head from Blender in.

We just want to provide some details about how we set up the Suzanne simulation in case you want to repeat it. Part I: Getting started and rendering a static sceneĪs our example, we will simulate the flow around a rather special object: The head of a monkey, affectionately called Suzanne, which is the unofficial mascot of Blender: The Suzanne head

Feel free to download the files if you want to follow along during the tutorial. We provide the data used in this tutorial (the configuration and mesh used for the calculations done by FLEXI, the state files used to post process the results in ParaView, the layout files in Blender and the scripts used to automate the whole process) in a git repository on GitHub.

In the second part, we will then discuss how to generate a dynamic rendering – when you want to render a series of images with time-dependent CFD data – think of rendering every time step of the CFD solution to generate a cool movie! the CFD solution data, is fixed and does not change during the rendering process – think of a single time step / solution file from your CFD data.

By static we mean that the object in the scene, i.e. We will split the discussion in two parts: In the first part, we will show you how to get the data into Blender, how to set up a simple scene and how to generate a static rendering. The focus is on how to use Blender to render already post-processed data, so there will be no step-by-step instructions on how to obtain the data – only a rough overview will be given in that regard. We are using data produced by FLEXI and post-process them using ParaView, but the procedure is applicable to other toolchains as well. In this post, we are going to show you how to take post-processed data from a CFD solver and render them in Blender, allowing you to present your simulation results in a eye-catching way.
