/*
* Revision history:
*
* $Log: not supported by cvs2svn $
* Revision 1.5 1995/03/07 21:46:24 pasacki
* (o) created LOG2_term indeces to replace all those ilog2() calls
* (o) extended most vector dimension loops to VIM(=3) as aid to
* collecting reqd terms in nonCartesian coordinates
* (o) added Harwell MA28 linear solver option (cf Makefile and sl_ma28.c)
* (o) checked port back to SunOS 4.1.3
* (o) eliminated various unused routines (eg, heat_conduct_with_mesh)
* (o) generic orthogonal curvilinear coordinates (note scale factors in
* fv structure, bulk integrals, but *not* in boundary conditions)
* (o) better insulation for fixed grid problems (fixed many UMR's)
* (o) made a default "point to a zero" for unused esp entries
* (o) used PROTO to help make code palatable to strict K&R compilers
* (o) added more test problems
*
* Revision 1.4 1994/12/22 22:03:52 racairn
* This is a 'purified' version of GOMA with boundary conditions separated
* into four separate functions (the first step in cleaning up this section).
* Also, this version includes lagrangian mesh motion using linear or
* nonlinear constitutive equations.
*
* Revision 1.3 1994/11/28 20:30:58 racairn
* Fixed some minor Bugs in the KIN_LEAK condition and implemented the
* Write Intermediate Results card to print data after each Newton Iteration
*
* Revision 1.2 1994/11/03 18:20:26 pasacki
* AIX 3.2 port; works for simple problems, not all problems.
*
* Revision 1.1.1.1 1994/05/24 19:56:30 pasacki
* initial checkin
