Dear gmsh, the following doubly nested loops gives me results that I do not
understand,
i.e. the index should count through from 0 to 19, without giving certain
indices twice.
I use the most recent nightly build of gmsh (2.6.2-svn)
Perhaps, I do not see the forest for the trees, can you comment ?
Thanks,Benedikt
numnpx = 4;
numnpy = 3;
/** loop over y period **/
For uy In {0:numnpy}
/** lop over x period **/
For ux In {0:numnpx}
index = uy * numnpx + ux;
/** compute index of redpoint id in 1-dimensional array **/
Printf("index - ux, uy, index = [ %g, %g, %g ]", ux,uy,index);
EndFor
/** close loop over y coordinates **/
EndFor
/** close loop over x coordinates **/
