Blender Ray-traced Render of OpenFOAM simulation
Posted on October 16, 2025 by Nicolás Diego Badano
Over the years, I've tried several times to produce proper ray-traced renders of flow simulated with OpenFOAM — but I always ran into severe artifacting. This week, I spent some time on it again, and I think I've finally found a workflow that works!
Dynamic Remeshing in OpenFOAM
Posted on September 17, 2025 by Nicolás Diego Badano
I've been experimenting lately with combining mesh deformation and remeshing in OpenFOAM. It's an interesting technique, with strong advantages and some drawbacks.
Flushing the toilet with OpenFOAM
Posted on August 13, 2024 by Nicolás Diego Badano
Flush toilets 🚽 are unsung heroes of modern life. Not only are they super practical; but they can be exciting as well from a fluid mechanics perspective!
Stratified flow with OpenFOAM
Posted on May 16, 2023 by Nicolás Diego Badano
We have been discussing a problem involving stratified saltwater/freshwater. I don't have much experience with this type of problem, so I'm doing a few OpenFOAM simulations to better understand how they work.
Stirring Coffee with OpenFOAM - Now as a human!
Posted on May 3, 2023 by Nicolás Diego Badano
Do you stir your coffee like Team Robot or like Team Human? In this video, we get to see how different those look, courtesy of Computational Fluid Dynamics (CFD).
Flow through a tunnel with columns - cyclicAMI
Posted on February 23, 2023 by Nicolás Diego Badano
Once in a while, I need to compute a steady state flow solution along a channel, or a conduit with regularly repeating geometry. Using cyclic boundary conditions can lead to very fast solutions for those cases.
Flow through a fish passage simulation - Delayed Detached Eddy Simulation (DDES)
Posted on February 7, 2023 by Nicolás Diego Badano
I've been fascinated with fish passages for a long time, and always wanted to simulate one. Unfortunately, the couple of proposals I presented for different projects in the past few years were not picked up.
Stirring Coffee with OpenFOAM
Posted on October 11, 2022 by Nicolás Diego Badano
Ever wondered what happens within your mug when you stir your coffee? In this video we get to see this process unfold, courtesy of Computation Fluid Dynamics (CFD).
Disk Entry in OpenFOAM
Posted on August 29, 2022 by Nicolás Diego Badano
After a couple of evenings of coding and testing I managed to get Adaptive Mesh Refinement (AMR) working together with a moving meshes in OpenFOAM v2112. It was quite a journey!
Stone Skipping with OpenFOAM
Posted on August 3, 2022 by Nicolás Diego Badano
Have you ever wondered how to solve flow interaction with a moving object, with any arbitrarily big displacement? OpenCFD's version of OpenFOAM includes a wide array of Overset-Grid-capable solvers, which are the perfect fit for this type of problem.
Local Time Stepping - Why and How?
Posted on July 11, 2022 by Nicolás Diego Badano
Sometimes your numerical problem is stiff, meaning you have two related timescales: one that is fast and requires a small time step to maintain stability, and the other much slower, which requires long simulation times to reach a steady state.
Weir with moving gate - Moving mesh and Cyclic AMI
Posted on June 21, 2022 by Nicolás Diego Badano
Have you ever wondered how to include a moving gate in your CFD simulations? There's actually quite a few ways to do that, but perhaps the most straightforward one is using a moving mesh region, combined with Cyclic Arbitrary Mesh Interfaces (AMI).
Attenuating spurious velocities in the air phase on free surface simulations
Posted on June 13, 2022 by Nicolás Diego Badano
Many times in multiphasic simulations (e.g. interFoam) of hydraulic problems, only the results of the water fraction are of interest, but due to poor mesh quality or non-optimal case setups, high velocities develop in the lighter air fraction.
Flow through bottom discharger Simulation - DualSPHysics
Posted on May 16, 2022 by Nicolás Diego Badano
I wasn't able to progress very much onto the validation plans for DualSPHysics. So far, I 've fixed the initial conditions, switched to a better temporal integrator and to a proper turbulence model, and I'm now running 'mesh' convergence tests.
Hydraulic Jump simulation - Rendering in Paraview
Posted on April 19, 2022 by Nicolás Diego Badano
I spent part of the Easter weekend playing with Paraview 5.10.1, trying to improve result rendering for a typical hydraulic problem, to make them easier to digest by less technically inclined customers.
