Operator with multiple objects with same names

3

Operator cannot handle multiple data carriers with same name. For example ``` from devito import Grid, inner, Function grid = Grid((10, 10)) u = Function(name="u", grid=grid) u.data[:] = np.random.rand(*u.shape) u1...

Resampling function inconsistent

* [ ] reproducer 1: ``` f= VectorTimeFunction(name='f', grid=grid, space_order=2) g=TimeFunction(name='g', grid=grid) ``` now: ``` f+g ``` gives one type of error, while ``` f-g ``` a completely different one...

When attaching M `SubDomain`'s to an N-dimensional grid M*N `SubDimension`'s are currently being created, but often some `SubDimension`'s can, and should, be re-used. Therefore, during the finalization of a `SubDomain`...

- If `LinearInterpolator._interpolate`/`_inject` could accept `sfunction` as parameters, no state would be required in the `LinearInterpolator` class and it could be singleton-ized (see https://github.com/devitocodes/devito/pull/1025#discussion_r358091918 ) - The initialization of `Interpolator`...

FR/RFC: optional kwarg to disable (some?) default operator arguments

1
