Appeal No. 94-2299
Application No. 07/623,324
Previously, boundary nodes of one block merely
abutted boundary nodes of an adjoining block thereby
creating [sic] an artificial boundaries within the
flow region. See Appellant’s specification at page
6, line 20 to page 7, line 8. It is submitted that
Appellant’s method uses one of the known grid model
generation tools to create an overlapping multiblock
grid model as claimed. It is therefore submitted
that the Appellant has adequately disclosed how the
nodes are picked and assembled.
Determination of steady incompressible fluid
flow by computer processing of the
pseudocompressibility equations in an iterative
fashion (in conjunction with the Navier Stokes
equations) is also known in the art. See
Appellant’s specification at page 2, line 17 to page
3, line 2; page 3, lines 13-15; and page 4, line 1
to page 6, line 7. Accordingly, the Appellant did
not provide in the disclosure the details of what
data processing system or software may be used to
solve the Chorin equations (equations (3) and (4) in
Appellant’s originally filed specification).
Indeed, the iterative process introduced by Chorin
dates back to 1967. It is submitted that the
Appellant has enhanced these existing methods based
on using an overlapping multiblock grid model whose
nodes are updated as claimed.
Specifically, prior to the processing of the
pseudocompressibility equations at each iteration,
Appellant updates boundary nodes of one block that
overlap to corresponding interior nodes of an
adjoining block. An updated boundary node is
generated by taking the difference between the
boundary node for the one block and the overlapped
interior node of the adjoining block. Support and
understanding for this claim language may be found
in Appellant’s specification at page 13, lines 8-11,
and page 8, line 23, to page 9, line 9 in
conjunction with FIG. 3. For example, prior to
