FlowSieve can coarse-grain any scalar fields, and can nominally process any vector field as well, provided that it first be passed through the Helmholtz projection step.
A lot / most of the diagnostic outputs are built around filtering velocity, but we've also filtered density fields using the coarse_grain_scalar.x
case file.
Good suggestion about the clarifying sentences! I'll add those.
Gotcha! Could be nice to illustrate the filtering of a scalar field as part of the basic tutorial as well. I know tons of people who want to filter scalar fields - so having an example for scalar fields in the tutorial could attract more users! 😃
Good point! I'll work on giving the Tutorials section (and documentation) a bit of an overhaul this week.
@NoraLoose the scalars tutorial has been added and the documentation and paper includes the line
computes coarse-grained scalar and vector fields for arbitrary filter scales, in both Cartesian and spherical coordinates
in the core features section.
Great, thanks for adding these clarifications and the tutorial! I'm closing this issue.
Is FlowSieve specialized in coarse-graining velocity fields? Or can you also coarse-grain tracer fields?
I think these are questions that many potential users will have. It would be great if 1-2 clarifying sentences can be included in the paper & documentation.
