[dune-pdelab] trouble with dune-pdelab trunk

[Oleh Krehel]

Hi,

I have another question. This is copied from the website:

Access to vector entries:

| x[lfsu.localIndex(i)]                               // old way
| x(lfsu,i)                                           // new way

Access to matrix entries:

| jac(lfsu.localIndex(i),lfsv.localIndex(j))          // old way
| jac(lfsu,i,lfsv,j)                                  // new way

Accumulate residual:

| r[lfsv.localIndex(j)] += value                      // old way
| r.accumulate(lfsv,j,value)                          // new way

In my case "lfsu" is PowerGridFunctionSpace<lfsuk,40>
(is it reasonable in terms of efficiency to use this?).
Can I index the child space as well as dof inside space
(i.e. x(lfsu,k,i) means ith dof of species k)?
Before I was using lfsu.getChild(k).
Now it's deprecated.
Also there's no longer a default constructor for the child space,
and I can't declare an array of child spaces,
just an array of pointers to them.
What's the alternative?

best regards,
Oleh Krehel
