Overview of the 2D Grid Generator for the Axisymmetric Bump Test Case of Bachalo and Johnson
The fortran program can be found in file gridaxibump.f. A description of the main parameters is given at the start of the file. Simply compile the file and run. The default output is unformatted and consists of a single long record in files x.dat and y.dat.
As supplied, the program generates a mesh of 220×80 control volumes and 221×81 grid nodes. This grid may be used to obtain a High-Re calculation.
For low-Re calculations, set cutoff = 0; the generated grids would be 220×100 control volumes, 221×101 grid nodes.
The grids are non-uniformly spaced in most regions as mentioned within the program. However, the expansion ratios between consecutive grids are maintained at constant values.
