DISPLAY
This case defines a calculation of the potential flow
about a half cylinder in a duct in the y-z plane. The
grid is generated by PIL commands giving a 'shear
transformation' and is non-orthogonal; so NONORT is set T.
The potential calculation is contrived by introducing a
uniform high resistance throughout the flow field. This
'Darcy' flow is mathematically equivalent to potential
flow.
This is done in Group 13 by setting DARCY=T, which
creates the appropriate PATCH and COVAL settings. An
analytical solution exists for this case to which the
results may be compared (see Milne-Thompson, 1962,
'Theoretical Hydrodynamics')
ENDDIS
DISPLAY
This case differs from the previous one only in respect of the
grid used. The grid is generated using the Laplace solver, which
derives the grid by solving for the grid corner coordinates as
dependent variables in a set of coupled non-linear equations.
