Currently, `UpdateCellList!` clears all cells and adds particles again. For use cases like SPH simulations where only small changes in position happen between updates, it will be much faster to only u…

We recently started getting a documentation build error on Read the Docs (see below). It looks like it's in the `charged_particle_radiography_film_stacks` notebook. I have a suspicion this error sta…

Running step-70 works just fine, but only just so :-)
In writing #15370, I spent a quality hour discovering the following. In the default input file, `parameters.prm`, we have

Matt O'brien would like to color particles by a background mesh field. Below is his e-mail request.
----------Start email----------
We store the temperature as a mesh variable defined on the mesh,…

**Describe the bug**
Doing a standard workflow for the spin density of neutral bulk aluminum (SCF > NSCF > Convert > J2 opt > J3 opt > DMC). The J2 optimization returns a higher variance/energy ratio…

**Is your feature request related to a problem? Please describe.**
Sometimes a domain or scenario is not big enough to fully leverage all available threads. This is especially true in non-mpi simulat…

**Describe the bug**
I expect the following two lines using different data layouts should have same computation result.
```python
ti.root.dense(ti.i, n1).dense(ti.j, n2).place(field) # layout 1

**Is your feature request related to a problem? Please describe.**
This issue is based not on the current master branch (as of 13/05/2024) but on the state of the code in PR #821 (`c060b02`), which s…

I am testing using the particle method to set up the crustal layer in a two-d subduction model. This layer is adaptively refined compared to the background. I guess some of you would have the knowledg…

I just found that the EPOCH codes are one-cell shifted when calculating the nearest boundary cell of the particles and interpolating the fields felt by the particles. Such a deviation would result in …
