Great to present at the #MFEM Workshop and a huge ty to @TzanioKolev and the MFEM team.

Runner-up in the Sim & Vis Contest: Single phase compressible Euler simulation using a DG discretization for #hypersonic flow around cylindrical obstructions on an arbitrary 2D adaptive grid

We can't wait for the free & virtual #MFEM Community Workshop on Oct 25 https://t.co/VHn7Cmkon5

@DOESBIR has funded the integration of #blastFoam and the #MFEM libraries to create #blastFEM - a very high-performance compressible flow solver.

A bit ‘meta’?…. A #3D #NeRF #AI reconstruction of an #NVIDIA #GPU, trained on an NVIDIA GPU, and rendered on an NVIDIA GPU..(and perhaps even viewed on Twitter using your NVIDIA GPU)!

Real-time #3D cityscape reconstruction leveraging @NVIDIAA Instant NeRF.

The technique uses #AI to create a 3D scene from 2D images, even filling in the blanks (obscured regions in the images) by training a tiny neural network.

[Synthetik @synthetik_tech]

Components that can ‘fail’ based on user-specified criteria have now been added to #blastFoam.

Once the criteria is exceeded, the obstruction is removed from the simulation - this can be based on the entire patch, or per cell for partial failures.

Lots of interest in modeling the afterburn of under-oxygenated high explosives.

#blastFoam provides three afterburn models:
1 Constant
2 Linear
3 Miller

Sim: @Livermore_Lab HEAF Tests (Kuhl 1998). 0.8kg TNT. Linear afterburn model [Q 16.3GPa, 2.4ms-4.4ms]

blastFoam-GPU: a GPU-accelerated implementation of the #opensource #blastFoam #CFD solver for high-explosive detonation and airblast.

With support from our @simflow_cfd friends we have leveraged the #RapidCFD CUDA toolbox that allows blastFoam simulations to be run on the GPU.
