I have a set of cells.Its' number ranges from 1~1000. Now.Because of (pre-processing software called gambit) model importing ,I need to transform the orginal cell set number from (1~1000)to (20001~21000).how can I do? another question is also similar . I want to change the VSET whose numbers is from 500 to 700. I must transform the original vset range to 20500~20700. how can I do?

concludely~ (Q1)change the CSET number(1~1000)to (20001~21000). (Q2)change the VSET number(500~700)to (20500~20700).

thanks for help~

It sounds like you are importing a grid from Gambit. If so, why don't you enter the offsets during the import process (see the offset command).

If the grid is all ready in Prostar, you have two options. You can write the cells & vertices to a file & then read them back in with an offset - see cwri, vwri, crea & vrea commands (you can also do this from the Nav Center using Export Data->Export Grids then Create and Import Grids->Import Grids). Or you can use cgen & vren to make a copy of the cells & vertices with the desired offsets. The commands would look something like this:

cset news crange 1 1000 1 *set coff 2000 *get cnum ncse cgen,2,0,cset cset,news,crange,coff + 1,coff + cnum + 1 vren,disc,mxv,cset

Either way you'll end up with two copies of the cells & vertices. So you'll have to delete the originals.

cset news crange 1 1000 1 vset news cset cdel cset vdel vset

Be careful if this is a block embedded in some other grid. You don't want to delete adjoining vertices!!

try Vgen command

thank you very much!!! the export&import command is good to use. thanks for help~
