| 176 |
|
| 177 |
Version 0.9.5.112 |
| 178 |
|
| 179 |
Solver interface |
| 180 |
- all solvers and integrators are now built as 'external library' DLL/SOs. |
| 181 |
- new ASCENDSOLVERS environment variable gives additional search path location |
| 182 |
that is checked when attempting to satisfy IMPORT statements. |
| 183 |
- Fixed behaviour scons when lex/yacc not available. |
| 184 |
- Many ASC_DLLSPEC qualifiers added as result of the expanded use of external |
| 185 |
libraries. |
| 186 |
|
| 187 |
Solvers |
| 188 |
- CONOPT no longer needs to be present at buildtime. This was possible due |
| 189 |
to permission from Arne Drud to add the 'conopt.h' file to our source code. |
| 190 |
- BLAS and LINPACK are now embedded in the LSODE DLL/SO. They are not |
| 191 |
part of libascend, which makes the main DLL about 1 MB smaller. |
| 192 |
- Some bugs in the DOPRI5 integrator identified (full testing still not |
| 193 |
completed). |
| 194 |
- placeholder for a future TRON solver (work still to do on that) |
| 195 |
- work underway on the IPOPT optimisation solver. |
| 196 |
|
| 197 |
Model library |
| 198 |
- Equations of state models from Krishnan. |
| 199 |
- Added ASCEND port of the standard GAMS example problem. |
| 200 |
|
| 201 |
Windows installer |
| 202 |

| 203 |
makes getting started with ASCEND much simpler for new users. |
| 204 |
- Added the user's manual (in PDF form) to the installer package. |
| 205 |
|
| 206 |
RPM package |
| 207 |
- A SUNDIALS RPM package has been submitted for inclusion in Fedora, making |
| 208 |
installation of ASCEND possible with a single download on that distro. |
| 209 |
- RPM divided into subpackages ascend, ascend-devel, ascend-doc. |
| 210 |
- Other work on building RPMs for a range of Linux platforms using |
| 211 |
the new OpenSUSE Build Service. |
| 212 |
|
| 213 |
DEB package |
| 214 |
- Fixed. |
