Previously only accessible in a password-<o:p></o:p>  protected menu, these presets can now be defined statically and <o:p></o:p>  invoked in silent-running mode.  Currently two presets are supported:<o:p></o:p>  solar processing and building solution implicitness. They are set <o:p></o:p>  as follows:<o:p></o:p>    *sim-toggle bld-soln-implicitness   1.0000<o:p></o:p>    *sim-toggle bld-solar-processing    enabled<o:p></o:p><o:p> </o:p><o:p> </o:p>Project Manager<o:p></o:p>---------------<o:p></o:p>- The file browsing facilities for editing BASESIMP descriptions has been improved.<o:p></o:p>- Optical data from Window 6.2 can now be imported.<o:p></o:p>- Optical data from TNO's WIS application can now be imported.<o:p></o:p>- The facility that archives model files to a 'tar' file has been updated.<o:p></o:p>- The facility that exports an ESP-r model to an EnergyPlus IDF file now generates<o:p></o:p>  the V3 format.  The EnergyPlus conventions for parent and child surfaces are now<o:p></o:p>  correctly supported.  Parent and child surface relationships are also now supported<o:p></o:p>  in the Project Manager.<o:p></o:p>- The error messaging related to scanning plant network files has been improved.<o:p></o:p>- By default, plant network files are now written in the verbose format.<o:p></o:p>- The QA reporting has been improved for plant network controls.<o:p></o:p>- The interface and file handling for internal surface convective coefficients has<o:p></o:p>  been improved.<o:p></o:p>- The model contents report for integrated performance views has been updated to<o:p></o:p>  cope with local climate files.  With this change, warnings about zero dates are<o:p></o:p>  no longer given.<o:p></o:p>- The interface that allows all the unreferenced vertices in a zone to be removed<o:p></o:p>  via one command has been updated.  This is useful for tidying zones with complex<o:p></o:p>  geometries.<o:p></o:p>- Support has been added to the Project Manager to allow it to read and<o:p></o:p>  write .cfg files that include the *mvnt flag; this is used for treating<o:p></o:p>  ventilation systems in the ideal HVAC models.<o:p></o:p><o:p> </o:p><o:p> </o:p>General<o:p></o:p>-------<o:p></o:p>- The programming structures that implement contextual help have been reconfigured<o:p></o:p>  to facilitate maintenance.  Concurrent to this, the information for many help<o:p></o:p>  dialogues has been improved.<o:p></o:p>- An annoying bug that caused the plant database manager to switch from graphic to<o:p></o:p>  text mode has been repaired.<o:p></o:p>- A number of variables have been added to the XML/CSV reporting facility.<o:p></o:p>- The out.dictionary format (utilized with XML/CSV reporting) has been altered<o:p></o:p>  to improve its clarity.<o:p></o:p>- Several small bug fixes related to stand-alone CFD simulations and Tecplot output<o:p></o:p>  have been repaired.<o:p></o:p><o:p> </o:p><o:p> </o:p>Additional Changes<o:p></o:p>------------------<o:p></o:p>- Many additional changes have been made that are transparent to the user.<o:p></o:p>  Information on these, as well as further details on all the above-mentioned<o:p></o:p>  changes, can be found in ESP-r Central's change log.<o:p></o:p><o:p> </o:p></div></body></html>
