TL;DR We ran the classic Beji & Battjes (1993) Delft flume (waves over a submerged trapezoidal bar, 8 wave gauges, 6 regular and 6 random wave conditions) with XBeach 1.24 (non-hydrostatic, 2 layers), SWAN 41.51 (spectral) and openTELEMAC v8p5r1 Read more
Expansion-chamber muffler transmission loss from Elmer, code_aster, FEniCSx and FreeFEM on cloudHPC: same mesh, same answer, where 1D theory fails.
Full car fire under a steel car-park frame with FDS 6.11.1, preCICE 3.3.1 and CalculiX 2.20 on cloudHPC: steel at 755 ยฐC, 34 mm deflection, โฌ16.
Why couple FDS to a structural solver? FDS is the most used fire model in performance-based fire engineering. Its solid-phase heat transfer is mostly one-dimensional through each wall cell (a 3-D option exists for simple obstructions). It has no Read more
We converted FDS inputs to CFAST automatically and compared CFAST, FDS 6.11.1 and experiments on 6 fire cases. Results, limits and speed-up.
TL;DR Why this case In October we released precice_aster, a GPL-3.0 connector that couples code_aster to OpenFOAM, CalculiX and any other preCICE participant, for both fluidโstructure interaction (FSI) and conjugate heat transfer. We presented it in a webinar with Read more
TL;DR New solver on cloudHPC: Kratos Multiphysics 10.4.2 (KratosMultiphysics-10.4.2). Upload a folder with ProjectParameters.json, the .mdpa mesh and the materials file, pick an instance and run: structural, fluid, FSI, DEM, MPM, convectionโdiffusion and co-simulation applications are ready to use, Read more
TL;DR Why this comparison Every rotating-machinery CFD job starts with the same choice: freeze the rotor in a multiple reference frame (MRF) and run steady, or actually move the mesh and pay for a transient run. OpenFOAM now offers Read more
How to model a jet fan that is not aligned with the FDS grid: louvered UVW vents vs a rotated GEOM fan, tested on cloudHPC with 5 LES runs, jet angles and costs.
Palabos (lattice Boltzmann) vs OpenFOAM on cloudHPC: cylinder validation and a 256ยณ TaylorโGreen vortex with run times, scaling and real costs.
