Revision 1129 - (view) (download) (as text) (annotate) - [select for diffs]

Added integrator_write_matrix routine to allow integrator matrices to be written out.
Modified integrator in PyGTK to output this matrix to a file in /tmp in the case where Integrator::solve fails.
Fixed a bug in densematrix_write_mmio.
The current implementation of integrator_write_matrix might not be quite right yet... needs some more thought.

Incorporated 'SolverParameters' functionality into 'Integrator', both at C level and C++/Python.

File length: 15208 byte(s)
Diff to previous 903
Removed BBOXWHINE (replaced with some one-time-only warnings for the moment)
Added ExtMethodDestroyFn to allow 'user_data' associated with external methods to be destroyed.
Implemented the destroy fn through to 'extpy' module.
Added 'name' as an extra parameter in the user_data for extpy, to help with debug msgs.
Moved 'solvernotes' to a file of its own (was part of listnotes.py)
Added 'repaint' to GTK 'tools' menu (for debugging)
Added 'python.h' to top of library, type files (pygtk) to stop silly warnings.
Working on some diagnosing of problems as noted in Simulation::checkInstance.
Removed some old comments from namio.h and others.
Renamed 'blsys' to 'sys' in integrator.c.
Some work on fixing up the J*v function for IDA (not yet complete).
Added new 'destroyfn' parameter (as NULL) to all calls to 'CreateUserFunctionMethod'.

File length: 15156 byte(s)
Diff to previous 854
Some success with IDA: fixed up the indexing dilemma and was able to
integrate 'johnpye/thermalequilibrium.a4c' for a short time span (but
through to 3000 s as with LSODE). I would blame lack of jacobian routine
in the first instance.

Added 'more properties' button in Properties dialog for a variable, to allow
values of ode_id, ode_type etc to be queried (but not changed).

Diff to previous 709
First tentative version in 'integration reporting':
Values of observed variables from the simulation are added to an Observer table after simulation completes.
This is not very efficiently coded at this stage but is a start.
Also some minor changes to text and comments in some base/generic files.

Diff to previous 704
Monster commit!
Lots of recommenting and reorganising of external relations-related stuff.
Replaced a lot of ascmalloc and asccalloc calls with the new ASC_NEW* macros.
Fixed (?) the problem Art is having with icons in PyGTK.
Turned on -Wall in SConstruct and fixed up a stack of warnings.
Removed the redundant exit(2) from after Asc_Panic calls and added __attribute__((noreturn)).
Set doxygen to create callgraphs to level 2, updated doxyfile to version 1.4.7.
Fixed up building of extfntest.c.

Diff to previous 669
- fixed a minor bug in the use of dimensions in samplelist
and a #define misuse in ospath.
- defined eolstyle unix on the trunk, as I have encountered
at least 4 too many mixed-eol-style-in-one-file files in trying to 
rebuild today. obviously committer discipline is insufficient.


Revision 669 - (view) (download) (as text) (annotate) - [select for diffs]
Added Wed Jun 21 07:00:45 2006 UTC (14 years, 7 months ago) by johnpye
File length: 14429 byte(s)
Merged changes from DAE branch (revisions 702 to 819) back into trunk.
This adds the Integration API to the ASCEND solver (in base/generic).
Also provides pre-alpha support for 'IDA' from the SUNDIALS suite, a DAE solver.
Many other minor code clean-ups, including adoption of new 'ASC_NEW' and friends (to replace 'ascmalloc')
Added some very sketchy stuff providing 'DIFF(...)' syntax, although it is anticipated that this will be removed.
