Revision Log
| Sticky Revision: |
Abstracted the internal integrator calls into a struct IntegratorInternals. Fixed up compile-time list of integrators. If IDA is not available, then 'INTEG_IDA' will not be defined. Added ASC_ASSERT_RANGE for assertions x in [low,high). Changed calling convention for integrator_get_engines().
Added placeholder for a C version of Art's DAE solver (named 'AWW') Added support for SPBCG and SPTFQMR Krylov solvers in IDA. Attempted separation of ascpy.i and solver.i (ongoing) Fixed an error message in typedef.c Fixed typo in ivpStepN.tcl Added correctly hidden Simulation() ctor.
Fixed a bug in slv_param_char. More work on IDA ongoing.
Implemented ATOLVECT, ATOL, RTOL parameters for the IDA integrator.
Incorporated 'SolverParameters' functionality into 'Integrator', both at C level and C++/Python. This shouldn't break Tcl/Tk as default parameters will be set and used invisibly.
Changed integrator_set_engine to return 0 on success. Fixed Integrator::setEngine to throw range_error / IndexError on invalid selection. Test suite contains testIDA that works now (more tests yet to come)
Fixed 'testLSODE' in test.py, added 'IntegratorReporterNull' that makes no output (for testing purposes)
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'.
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).
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.
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.
- 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.
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.
