Grids - Axisymmetric Impinging Shock Boundary-Layer Interaction

A series of 4 nested grids are provided. The larger grid files have been gzipped. Each coarser grid is exactly every-other-point of the next finer grid, ranging from the finest grid with 6,072 cells to the coarsest grid with 759 cells. The following figure shows a portion of the coarse grid grid (2 levels down from the finest grid).

Note: be sure to use double precision when reading the grids!

All grid files below can be downloaded together in one zip file: aisbli-2d-grids.zip, aisbli-3d-grids.zip

PLOT3D Files

The structured PLOT3D grids are given in two different ways, as 2-D grids (x-y plane) or as 3-D axisymmetric grids (two planes rotated through 1 deg from each other; one plane rotated 1 deg from the x-z plane). You may use whichever is more convenient for your particular application. If you get the 2-D grid version, then you must create an axisymmetric grid from it on your own.

Structured 2D grids

Format for the structured 2D grids is PLOT3D-type, formatted, MG, 2D (nbl=1) - note that you must use double precision when reading! :

      read(2,*) nbl
      read(2,*) (idim(n),jdim(n),n=1,nbl)
      do n=1,nbl
        read(2,*) ((x(i,j,n),i=1,idim(n)),j=1,jdim(n)),
     +            ((y(i,j,n),i=1,idim(n)),j=1,jdim(n))
      enddo

Structured 3D grids

Format for the rotated-plane structured 3D grids is PLOT3D-type, formatted, MG, 3D (nbl=1, and idim in this case is 2) - note that you must use double precision when reading! :

      read(2,*) nbl
      read(2,*) (idim(n),jdim(n),kdim(n),n=1,nbl)
      do n=1,nbl
        read(2,*) ((x(i,j,k,n),i=1,idim(n)),j=1,jdim(n),k=1,kdim(n)),
     +            ((y(i,j,k,n),i=1,idim(n)),j=1,jdim(n),k=1,kdim(n)),
     +            ((z(i,j,k,n),i=1,idim(n)),j=1,jdim(n),k=1,kdim(n)),
      enddo
