MultiMeshFunction can't be integrated

[Jørgen Dokken]

Since MultiMeshFunction not is a subclass of ufl.Argument it can't be integrated.

[Anders Logg (Chalmers)]

Yes, this is a known issue. As you say, UFL is not yet aware of MultiMeshFunction. It needs to be a subclass of ufl.Coefficient (not ufl.Argument that I mentioned to you earlier, my bad).

[Anders Logg (Chalmers)]

Will not be fixed before the summer.

Removing milestone: 1.7 (automated comment)

[Martin Sandve Alnæs]

Maybe support should be introduced in ufl. The ufl.Coefficient assumes a single function space.

[Anders Logg (Chalmers)]

@dokken Is this working as expected now?

[Jørgen Dokken]

@logg: I think this can be set as fixed, as it works for all cases I've encountered.

[Anders Logg (Chalmers)]

Fixed.
