C code for node renumbering?
Anyone out there have any C code for node renumbering of a finite element mesh? (It's for bandwidth reduction)
Re: C code for node renumbering?
the PETSc developpers have translated F77 code from sparspack (I believe) into C using f2c; it's now part of the PETSc library http://www.mcs.anl.gov/Projects/petsc/petsc.html.
For some time I' ve been using:
ALGORITHM 582, COLLECTED ALGORITHMS FROM ACM. ALGORITHM APPEARED IN ACM-TRANS. MATH. SOFTWARE, VOL.8, NO. 2, JUN., 1982, P. 190. (http://www.math.psu.edu/dna/contents/toms.html)
which is in F77, but translating it into C should pose no problems, I believe.
