This whole subroutine looks like it's the same as
deformations
, only callingstrain_ratesT
instead ofstrain_rates
.Should we instead keep the existing
deformations
subroutine, and add anif (grid_system == 'B') .. else ..
block for callingstrain_rates
vsstrain_ratesT

Good eyes, @phil-blain .
I would prefer to reuse as much code as possible. Initially it's fine to have duplicative code, while developing, but if it makes sense and is easy to merge/clean up enroute, let's do it...

Yeah, upon further inspection with @JFLemieux73, it's not exactly the same, as the B grid version does the average of the 4 corners:

whereas the CD-grid version already has the quantities at the tracer point, so it just computes the deformations without averaging:
