Let's start with the advection equation in 1D
```
∂φ/∂t + u ∂φ/∂x = 0
```
where `u = constant` and `φ(x, t)` a tracer concentration.
- [ ] Start with a gaussian and advect it for time `t` s…

## Purpose
For global runs, we currently set up a spherical shell domain (extruded FD) and create fields that are defined everywhere on the domain. The issues arise in three areas:
- Interpolation: …

Thank you Jan,
I was absent for a while for finding a job and did not conduct the research a period of time. Now i want to change the model for example like a slope. And first i want to try to…

Hi developers,
For a while now I've been seeing temperatures going below surface T in my models, and so has Eric van der Wiel. For example I attach a prm (which is a modification to the steinberger…

I have found that when running a Sedov blast problem with the PPM method, with periodic boundary conditions, mass and momentum are not perfectly conserved, in particular when the center of the blast i…

In the example below, the model crashes reporting a GPU illegal memory access error. The CFL number is intentionally set to a large value, under which the model will encounter numerical instability. I…

I also flirted with the idea of using the fft solver as a preconditioned.

You reckon this would …

Currently, the center of mass computation does not check if all particles of a molecule are adjacent, or if some particles are wrapped into the simulation cell. If a molecule is partially wrapped, the…

Let me start by saying this is a help request; not as issue as such. If there is a more appropriate place for those, I am all ears.
On a high level; I want to solve a 3d laplacian with non-constant…
