Minutes

Present: CW (minuter), JB, KS, DH, DD, RNH, RK, PB, DS, NB, UZ

Apologies:

JMC MEng/Applied MSc projects

DH: Coupled domain stuff.
JB: ROL stuff?
RNH: Point evaluation for bendy meshes.
DH: Similarly mesh-to-mesh interpolation with more complicated nodes.

CW/JB: libsupermesh needs updating

A MacOS user has failed to build libsupermesh due to the fact that the libspatialindex inside of libsupermesh is very old. How should we proceed? Why do we have 2 libspatialindex's (here and here)??

JB: I don't think RTree PyPI package will save us: The headers are not bundled in the wheel, so libsupermesh cannot link.
Action point JB: submit a PR that bundles the headers with RTree so we can link to it. We can then find the right files by importing rtree and asking where its files are.
DH: But libsupermesh uses non-public API bits of libspatialindex. We should see if we can drop it and use mesh-to-mesh interpolation instead.

DH: How to fix MacOS build

RNH: MacOS command line tools version 15 is apparently buggy.
Action point JB: Fix PNetCDF build by defaulting to downloading BLAS with MacOS (--with-blas=download).
Action point KS: xfail tests and update PETSc fork.
