— ae.r now generated using def2write_r like cse?.r
fix_c.r called at ese2rdae stage so that pow gets fixed in ae.r.These changes produce the desired result (optimised algebraic equations) but
have highlighted a problem; when optimisation fails, Reduce does not write
a result. For complicated systems, this can lead to missing assignments in
the resultant code. (user: geraint@users.sourceforge.net, size: 6188) [annotate] [blame] [check-ins using] [more...]

## $Id$
## $Log$
## Revision 1.12 2001/07/23 23:31:17 gawthrop
## Added -cr option to load CRs first - avoids alg. loops with R
## implementation of mutiports.
##
## Revision 1.11 2001/07/06 00:46:50 gawthrop
## Added -cr option -- forces cr to be loaded before the ese.r file
## This avoids causality problems when using multi-port Rs to represent
## arbitary equations
##
## Revision 1.10 2000/11/30 15:23:16 peterg
## Taken out all subsystem stuff - now done in mtt using
## mtt_make_subsystems
##
## Revision 1.9 2000/09/07 12:18:31 peterg
## Prettified layout of this file
##
## Revision 1.8 2000/09/07 12:07:26 peterg
## *** empty log message ***
##
## Revision 1.7 2000/09/01 13:34:15 peterg
## Exit on option error
##
## Revision 1.6 2000/09/01 13:30:32 peterg
## Added -partition switch
##
## Revision 1.5 2000/09/01 12:14:57 peterg
## Added connecti9ng inputs
##
## Revision 1.4 1998/04/07 15:06:46 peterg
## Correct log file name
##
## Revision 1.3 1998/03/07 12:57:19 peterg
## Fixed logname bug
##
## Revision 1.2 1998/03/07 12:51:20 peterg
## This is the new version of ese2dae - it does not do the CRs at this
## stage to give reduce an easier time.
##
## rese2ese_r does the constitutive relationship bit
##
## Revision 1.1 1998/03/07 12:49:31 peterg
## Initial revision
##
## Revision 1.12 1998/01/31 16:22:59 peterg
## Added IF MTTNx>0 THEN and IF MTTNy>0 THEN before the relevant
## assignements of MTTdX and MTTY to themselves.
##
## Revision 1.11 1997/09/18 09:45:08 peterg
## Canged the comment about linux reduce -- reduce reads this for some
## reason.
##
## Revision 1.10 1997/09/15 14:21:18 peterg
## Reads ese file twice to avoid a bug in Linux reduce !!!???
##
## Revision 1.9 1997/08/30 09:59:31 peterg
## Changed mehtod of writing out mtty to avoid a strange segmentation violation.
## Now uses MTTY := MTTY; approach.
##
## Revision 1.8 1997/04/23 09:31:20 peterg
## Now reads in the (top level) def file in the generated reduce code.
##
# Revision 1.7 1997/04/23 09:23:15 peterg
# Two argument version in preparation for heirarchical version
#
# Revision 1.6 1996/11/21 15:47:48 peterg
# Now inputs _params.r not _sympar.r
#
## Revision 1.5 1996/11/02 10:17:35 peterg
## Removed default constitutive relationship input.
##
# Revision 1.4 1996/09/12 12:10:05 peter
# Now reads the default constitutive relationship file.
#
## Revision 1.3 1996/08/25 09:43:26 peter
## General error handling.
##
## Revision 1.2 1996/08/25 08:31:28 peter
## Error handling added.
