An example of an error indicator is driven non-conforming mesh adaptivity for #advection problem using upwind high order #DG. Wind velocity is discretised by vector potential function in H1 one space. #MOFEM can do very cool things. That technology is implemented for 2d/3d problems. #FEM #FEA #HPC

Example #code is here:

Our new paper on modelling the #spatiotemporal dynamics of a beneficial genetic variant is out @eLife.

We extend a #diffusion method for inferring the spread of a strongly selected allele, originally developed by Novembre et al. (https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.0030339). We now incorporate #ancientDNA and allow for #advection dynamics.

The most computationally expensive part of such models is the transport (by #advection and #diffusion) of #biogeochemical #tracers (zoo and #phytoplankton #nutrients, organic and inorganic #carbon, etc) with the #ocean #flow.

The more tracers we include to represent the complexity of #ocean biogeochemistry, the slower are the model runs. Same problem arises when the #spatial #resolution of an #ESM increases.

Biogeochemistry models can become a bottleneck in #ESM computations. 2/

I started doing this because I realized I didn't like what was out there. I'm a Classical musician and dance didn't have enough "stuff" in it to keep me interested. So here I am mashing up music as a hobby and appreciating another art form. Live Mix: Advection - Dimensions & Tommy Jayden - Deja Vu
