title: RZBRICK tags: review —


Builds a brick mesh and generates a nearest neighbor connectivity matrix. This command is similar to the rz command format except here we have symmetry flags to input. A second format specifies that a mesh be created and connected.

Argument Description — | — xyz | specifies Cartesian coordinates. rtz | specifies cylindrical coordinates. rtp | specifies spherical coordinates. ni,nj,nk | number of points to be created in each direction. xmin,ymin,zmin | minimums for coordinates. xmax,ymax,zmax | maximums for coordinates. iiz,ijz,ikz | if =0 then mins and maxs are used as cell centers
if =1 then mins and maxs are used as cell vertices iirat,ijrat,ikrat | ratio zoning switches (0=off,1=on) xrz,yrz,zrz | ratio zoning value - distance is multiplied by the value for each subsequent point. name | name of pset containing starting point number isym,jsym,ksym | symmetry flags - not documented

Warning: This command does not create a 2D grid, it has mem errors:

rzbrick /xyz/5,10,1/0. 0. 0./10. 20. 0. /1,1,1

for 2D this will work:

  mo create cmo1///quad \   quadxy 5 5/ 0. 0. 0. / 20. 0. 0./20. 20. 0. / 0. 20. 0. ]   rzbrick /xyz/5,5,1/1,0,0/connect \   dump gmv quad5x5.gmv \


rzbrick /xyz rtz rtp/ni,nj,nk/xmin,ymin,zmin/xmax,ymax,zmax/ \ iiz,ijz,ikz/[iirat,ijrat,ikrat/xrz,yrz,zrz/isym,jsym,ksym]



Use this option with quadxyz to connect logically rectangular grids.



creates a hex grid 2x1x2 cells in the unit cube


creates a hex grid inside the hexahedral specified by the 8 corners passed to quadxyz
