Velocity-Based Diffusion (VBD) - A Novel Physically-Based Interpolation Method For Bathymetric Data
Posted on November 18, 2025 by Nicolás Diego Badano
Last week, I attended the 𝘟𝘓𝘐 𝘈𝘳𝘨𝘦𝘯𝘵𝘪𝘯𝘪𝘢𝘯 𝘊𝘰𝘯𝘧𝘦𝘳𝘦𝘯𝘤𝘦 𝘰𝘧 𝘊𝘰𝘮𝘱𝘶𝘵𝘢𝘵𝘪𝘰𝘯𝘢𝘭 𝘔𝘦𝘤𝘩𝘢𝘯𝘪𝘤𝘴 (MECOM 2025) in Buenos Aires. I thought it would be a good idea to share 𝗼𝗻𝗲 𝗼𝗳 𝗺𝘆 𝗽𝗿𝗲𝘀𝗲𝗻𝘁𝗮𝘁𝗶𝗼𝗻𝘀, as it covers a topic I originally introduced on LinkedIn, but was a bit vague about.
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!
Physically based interpolation of bathymetric data
Posted on April 1, 2024 by Nicolás Diego Badano
This Easter weekend I finally found a few hours and decided to toy around with an idea I've had for ages: trying to create a physically-informed intepolation method for river bathymetries.
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

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).
Monochromatic vs spectrum waves
Posted on October 6, 2022 by Nicolás Diego Badano
In natural conditions, waves are seldom regular, even when produced by almost uniform wind conditions. Instead, a spectrum of amplitudes is generated, which has been repeatedly studied in the literature.
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.
Flow around a cylinder - Adaptive Mesh Refinement (AMR)
Posted on July 4, 2022 by Nicolás Diego Badano
What if your mesh could be adapted automatically to improve the accuracy of your solution? That's exactly what Adaptive Mesh Refinement (AMR) is all about.
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.
PhD Thesis Defended
Posted on October 23, 2021 by Nicolás Diego Badano
The day has finally arrived. On Friday, I defended my thesis and received my PhD in Engineering from the University of Buenos Aires.
Low-Reynolds Rough Boundary Conditions for OpenFOAM
Posted on April 15, 2021 by Nicolás Diego Badano
I released a new set of boundary conditions for simulating rough surfaces in OpenFOAM, using fine meshes with near wall distances around y+=1 or lower.
PRip v0.3 released
Posted on December 17, 2015 by Nicolás Diego Badano
PRip is a tool for digitizing scientific plots and graphs, getting numeric data. It works similarly to the popular g3data application, but has a greater emphasis on usability, precision and portability.
