Modified Fri Jan 5 13:45:13 2007 UTC (16 years, 8 months ago) by johnpye
File length: 3689 byte(s)
Diff to previous 903

Changed integrator_solve to return 0 on success
Changed integrator_checkstatus to return 0 on success
Some flow-through changes as a result of these.
Fixed problem with reporting of errors in do_method (gtkbrowser.py)
Expanded error msg in integrator.cpp
Fixed catching of Integrator C++ exceptions in integratorreporter.py.
Removed M.checkStructuralSingularity() in TestSteam.testdsgsat -- causes crash (why?)

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).

Integrator remembers 'duration' used previously.
Implemented interuption of integration with 'stop' button.

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.

Some progress on a rewrite of the Observer funcitonality so that it can be shared with the IntegratorReporter.

Revision 669 - (view) (download) (as text) (annotate) - [select for diffs]
Added Wed Jun 21 07:00:45 2006 UTC (17 years, 3 months ago) by johnpye
File length: 2408 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.
