Dear Firedrakers, I am solving a 3 fields coupled problem with Firedrake. I would like to use a multiplicative block-preconditioner but PETSc complains about a local size not being correct. [0] Arguments are incompatible [0] Local size 9 not compatible with block size 2 I have noticed that the use of a MatAij solves the problem (see comment in line 132) but I am afraid this is just a side effect. Am I missing something? Thanks in advance, Nicolas
