What's new in The Simple Hydraulic Calculator 2.3.2
May 16, 2014
- This is a maintenance release that fixes and changes the following:
- A Pe unit conversion error in the demand pie graph (menu item "View" -> "Demand Graph") has been corrected.
- An improper unit conversion warning is no longer displayed when a file that uses an equivalent k-factor has it's units changed.
- The hydraulic demand graph now correctly adjusts for relative elevation difference to the water source when the base of riser node name is not entered or is invalid.
- The "Popup Helper" no longer suggests the wrong thing when editing within a command line.
New in The Simple Hydraulic Calculator 2.3.1 (May 16, 2014)
- This is a maintenance release that fixes and changes the following:
- The system demand pie graph's elevation pressure has been corrected (menu item "View" -> "Demand Graph").
- File properties have been added to override the "System Designer" and "Company" SHC Options settings. (See menu item "File" -> "Properties", "Project" tab.)
- SHC now highlights (as a warning) very short pipe lengths and low minimum sprinkler head discharge values. These warnings do not prevent calculation.
- Convergence characteristics have been improved for source calculations with steep water supply curves.
New in The Simple Hydraulic Calculator 2.3.0 (Apr 30, 2011)
- This release measurable improves SHC's ability to find a solution by:
- Cubic spline interpolation is now used to find the friction factor in the critical region of flow when the Darcy-Weisbach formula is used for friction loss.
- SHC now adjusts for velocity regardless of flow direction when velocity pressures are used in the hydraulic calculation.
- SHC will now slightly relax its very strict convergence requirements when these requirements are preventing a successful solution.
- SHC has also gained new editor abilities (see the Edit -> Change menu items) and some minor bugs have been squashed.
New in The Simple Hydraulic Calculator 2.1.3 (Jun 15, 2010)
- Corrects a hydraulic demand graph error that can occur when the water source static pressure is not adjusted properly to the "base of riser" node.
New in The Simple Hydraulic Calculator 2.1.2 (Jun 15, 2010)
- Corrects the reported head count when "system helper" commands are used.
- Corrects the reported head count when the "HC" command is used.
New in The Simple Hydraulic Calculator 1.4.8 (Jul 3, 2009)
- TSHC will now perform a source calculation on fixed flow systems (systems that do not use "Flow" or "Head" commands) when the "All" command is used. Previously, a demand calculation was always performed.
- The tree system example in the manual has been corrected to accurately represent the system diagram shown in the manual. The corresponding "example3.shc" file has also been updated.
New in The Simple Hydraulic Calculator 1.4 (Jan 30, 2007)
- added a "pop-up" helper
- customizable insert menu
- over 25 new pipe materials
- Vista compatibility
New in The Simple Hydraulic Calculator 1.3 (Sep 8, 2006)
- 1. Mislabeled unit in report for metric users corrected.
- 2. Real time error checking (highlighting) now checks fitting code against pipe size instead of checking for valid code only.
- 3. Report update - now choose A4 paper size with landscape layout, letter paper with landscape layout, or a more compact letter paper with portrait layout.
- 4. Font selection moved to options dialog (Tools->Options).
- 5. The editor's real time highlighting and background colors are now user selectable from the options dialog (Tools->Options).
- 6. Options dialog (Tools->Options) extensively revised.
- 7. Advanced highlighting option added (Tools->Options). This adds a few more real time error checking tests that may run too slow on old computers. Checks added are:
- a) pipe sizes checked against pipe type
- b) flow command coordinate bounds verified against Main and Line commands
- c) METRIC or ENGLISH command will set units used for checking, if present.
- 8. LiveLook feature shows information for pipe or node at cursor position in bar just below toolbar.
- 9. Cursor now remembers x position when moving up or down.
- 10. Drag and drop editing allows selections to be moved in the editor with the mouse.
- 11. Added MainV command for creating crossmains with variable distances between branchlines.
- 12. Modified Line command to allow variable spacing between heads along the branchlines.
- 13. New grid/tree flow diagram is available in calculation reports when
- TSHC's grid commands are used.
- 14. Improved print quality for all graphs.
- 15. REDUCE command could fail to reduce properly on some complex grids.
- This has been corrected.
- 16. The report's summary page wrapped text around to the next line when an entry was too long. This could cause values to be shown out of place. Wrapping of text has been disabled.
- 17. Undo and Redo buttons have been added to the toolbar.
- 18. Removed 40 character limit for designer and company information text (Tools>Options).
- 19. Fixed a large memory leak.
- 20. Fixed help file registration entry.
