Can anyone give me any advice or helpful info on using PDECOL. (PDECOL is one
of the algorithms available through NETLIB for solving systems of partial
differential equations.) I am having some difficulty locating the original
paper on the subject, and haven't completely grasped the way in which boundary
conditions are set up in the code. If anyone knows of a good user's manual, (
or some reasonable facsimile thereof) I'd really appreciate hearing of it.

Also, if anyone has had much experience using this code, I'd like to hear
about it. My problem is that I wrote a code to solve a system of partial's
using explicit finite differences, then implicit finite differences. Both are
too slow ( as defined by the end user). I need a good diffeq solver for the
to run using fortran on a 486/33. I've heard that PDECOL is (can be) quite
fast. Any comments?

                Thanks in advance
