[petsc-users] PCCOMPOSITE and ApplyTranspose

[Andrew T Barker]

I've made a PCCOMPOSITE that contains two PCSHELLS, both of 
which have a transpose set with PCShellSetApplyTranspose().  
However the composite PC does not seem to support the 
transpose:

[0]PETSC ERROR: No support for this operation for this object 
type!
[0]PETSC ERROR: PC does not have apply transpose!

The code runs fine with the composite replaced with either of 
the shells by itself.  Of course I can implement my own 
composite as a PCShell with a transpose easily enough, but I 
was wondering if this was expected or if I am making some 
other mistake.

I am using Petsc 3.0.0.

Thanks,

Andrew
