Changeset 1159 for palm/trunk/SOURCE/parin.f90

Message:

Bugfix: In case of non-cyclic lateral boundary conditions, Neumann boundary conditions for the velocity components at the outflow are in fact radiation boundary conditions using the maximum phase velocity that ensures numerical stability (CFL-condition).
Logical operator use_cmax is now used instead of bc_lr_dirneu/_neudir.
