Fixed problem with 'v' (spec vol) verusus 'vel' in one equation! Added new formulation where (rho*u) equation is rewritten as (u).
Fixed value of 'dz' in dsgsat.a4c. Added test case for saturated steam in terms of (u,v) Other minor debug output changes.
Reduced slv_far_from_nominals bignum value in PyGTK GUI to 10.0 Added some more nominals to the steam models.
Added support for slv_far_from_nominals in C++/Python layer. Converted 'child not found' from error to CONSOLE_DEBUG message. Added some nominal values in iapwssatprops.a4c. Added getRealPref in preferences.py.
Got paranoid about turning off signal handling... added '#ifdef ASC_SIGNAL_TRAPS' anywhere that signal handling referenced. Signal handling is OFF by default now.
More sensible slv_param_real bounds in LSODE and IDA. Run ode_init by default for dsgsat.a4c. Fixed dependencies for swig python outputs. Fixed [X] button on Integrator dialog.
Attempting to fix sunos test.py problem. Preparting dsgsat2. for IDA.
Converted slv3 (QRSlv) to new slv_param_bool (etc) parameter code. Adding a testcase for dsgsat with LSODE as well as IDA. Fixed some remaining external function calls (needing userdata ptr). Adding LSODE parameters 'METH' and 'MITER' for setting AM and BDF methods. Rerranged v_expr in iapwssat.a4c. Removed lower bound on mdot in satsteamstream.a4c.
Got rid of hg_expr pivot problems on load
Fixed the 'A_w' problem by adding some default values
Removed some unattached vars from dsgsat2.a4c Rearranged hf_expr in iapwssatprops.
more...
dsgsat behaving correctly in steady-state mode
Added ability to show all fixed variables in a model using PyGTK interface.
Updated comments
Added some more user error messages from the solver. Added detection for the MFGRAPH library, which will be used to output GraphViz files based on the incidence matrix.
Make dsgsat2.a4c load without EXTERNAL method calls.
Fixed a bug introduced into slvDOF_structsing. Fixed an LD_LIBRARY_PATH problem with test.py
simplified slv_check_bounds call.
Adding integration test in TestSteam.testdsgsat. Naming couple of anonymous structs.
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?)
Several changes to get BinToken compilation active again from PyGTK interface. Still not working but the problems now are in the C layer. Tidied doc for slvDOF.h Changed BinTokenSetOptions to saner use of strings -- no more 'taking ownership' of char arrays passed. Added Compiler.use_binary_compilation option in PyGTK GUI. Moved all the bintoken stuff out of class Type and into Compiler, where it should be (C++).
solve.py raises ImportError if 'browser' object is not available (right approach?) Freeing some variables in dsgsat2.a4c. Returing Py_None from extpy routine in 'browser' object not defined (eg during non-GUI unit testing) Error reporting from extpy import handler (ongoing) Timeout in versioncheck (when server unavailable) A little more tinkering with IDA.
Moving this file from my (separate) dsg-transient project into ASCEND.
