CoolSim 5.4.180 preview 3

This is an early build of the CoolSim desktop app, based on CoolSim 5.4.180. It installs as CoolSim 5.4 Preview, beside your current CoolSim, so you can try it on real models and go back at any time. Sign in with your usual CoolSim account. If you have preview 2 installed, this one replaces it.

What’s new

Changes from CoolSim 5.4.180. The CoolSim 5.4 changelog lists every build and what changed in each.

New in preview 3

• A new 3D view. The model view is drawn with current web graphics (Microsoft Edge WebView2) in place of a 3D engine from 2011. The mouse and toolbar controls work as before. Two curved arrows over the view cube turn the view 90° left or right; in the top view, the tile row and column labels turn with the plan.
• Complete energy files. In 5.4.180 the energy file sent with a job stopped part-way whenever the room held a block without a heat load, and otherwise kept the heat of only one block. The preview adds up every block’s heat load and writes the whole file, so energy results can differ from 5.4.180. Model and airflow files are unchanged.
• PDUs in models saved by CoolSim 5.3 export. CoolSim 5.4 stopped with an error while exporting such a model if the 3D view had not drawn the PDU yet, for example with Optimize load time on. The preview gives those PDUs their top and bottom openings, as CoolSim 5.3 did.
• A supported library database. The object library now runs on Firebird 5 in place of Firebird 2.5, which dates from 2010 and has had no updates since 2019.
  • The first start after installing takes about 10 seconds.
  • Library pages show every column. Columns with names longer than 27 characters were missing.
  • Adding parts works on Windows set to use a decimal comma.
• The Reports tab says what fills it. A new project shows No report yet and names the two toolbar buttons that make a report, instead of a blank page or an Invalid window handle error.
• The Library panel stays open when the pointer crosses the toolbar.
• View Message, the Editor Analyzer and Object Summary show their tables in WebView2 in place of Internet Explorer.
• Packages. Models and libraries packaged by the preview open in your current CoolSim and the other way round. Opening a package never writes files outside its own folder.
• The memory chart on the status bar no longer uses more memory each time it refreshes.
• Flatter, clearer tabs across the app.

Removed in preview 3

• Python scripting. The script editor, the Python shell, the Python, Utility and PowerShell console tabs, and Edit Script are gone. Templates or import files that carry Python, and -run with a .py file, report Script Not Run instead of running it. CoolSim’s own built-in steps no longer use Python and write the same files as before. If you rely on your own Python scripts, write to support@coolsimsoftware.com.

Also included, from preview 2

• Moving a group no longer lifts ceiling grilles or cutouts. Previously, each move of a group raised every ceiling grille in it by 0.5 mm and every floor cutout by 1 mm. Even 0.5 mm leaves a grille sitting just off the ceiling, and the solved job then shows almost no air through it. Group members now keep their height, the same as when you move a single object. Installing the preview does not change models you have already saved.
• Undo and redo are dependable.
  • Undoing a group move puts every member of the group back.
  • Undo works after Redo.
  • A new edit clears the Redo history, so Redo can no longer replay an old change on top of new work.
  • Undo keeps recording after you cancel a Save or Open.
  • Undo with nothing left to undo no longer shows an error.
  • Changes made in an object’s properties dialog can be undone.
  • Undo and Redo from the menu now update the 3D view.
• Jobs with a PDU placed after other objects no longer fail on the server. The job’s parameter file counted obstructions wrongly when a PDU was not the first object in the model.
• Sloped polygon blocks keep their slope. Blocks extruded along X or Z, such as a sloped soffit, were sent to the solver flat.
• No more partial uploads. If exporting the model fails part-way, CoolSim now stops, tells you which file failed, and sends nothing, instead of submitting an incomplete model.
• Silent install for IT. CoolSimSetup_5.4.180_preview3.exe /S installs unattended, with the libraries and work area in place. The preview takes no .csp file association, so double-clicking a model still opens your current CoolSim.

Before you install

• The Microsoft Edge WebView2 Runtime draws the 3D view. Windows 11 and most Windows 10 machines have it already. If the preview says it is missing, install it from Microsoft.
• Run one CoolSim at a time. The preview and your current CoolSim share the same libraries, settings and work area. Close one before opening the other.
• Make library changes in your current CoolSim. Both read the same library parts, but each keeps its own index of them. The preview picks up parts added, changed or removed in your current CoolSim the next time it starts; that start takes about half a minute. Your current CoolSim does not see parts added or removed in the preview.
• Sign-in is shared. Signing in to one signs you in to both.
• Windows SmartScreen will warn that the installer is from an unrecognized publisher. Choose More info, then Run anyway.
• Your models, libraries and work area (C:\Users\Public\Documents\CoolSim 5.4) are the same ones your current CoolSim uses.

Going back

Uninstall CoolSim 5.4 Preview from Settings → Apps. Your current CoolSim is left exactly as it was. The preview leaves behind the work area, which holds your own models, and its own library index files in the library folders, which your current CoolSim does not use.
