Dear DIVA Users,

We recently released DIVA 2.1.1.0 - Beta, available for download from the Solemma webpage. Since there was never a blog post made for the DIVA 2.1 series, below is a list of the major features and bug fixes. A complete list, as always, can be seen in the last three entries of the changelog. There are no updates to the thermal toolbar components with this release, but some changes are planned for the next DIVA release.

Before installing, we recommend you backup your DIVA license file (diva.lic) and any custom materials or schedules and then delete the C:\DIVA\ directory.

New Toolbar Features

  • The Illuminance from DA option under Load Metrics now allows visualization of the hourly illuminance results from Daysim. 
  • When simulation errors occur, the option to launch a batch window that does not automatically close is given. This is useful for troubleshooting simulations and posting error messages on the DIVA forum.
  • The DIVA installer now loads the plugin and toolbar directly into Rhino5 32 and 64-bit versions.
  • DIVA now installs Python in its own subdirectory so that our installer will not interfere with other Python installations that may be present on your machine. This means there are no more windows to click through when installing DIVA, and users can just allow permissions to a single folder, C:\DIVA\.
  • Radiation map images can now be run for all saved views. This takes advantage of the Radiance ambient cache and will be faster than running each view separately.
  • Radiation Map (Grid-Based) simulations now have the option to use Daysim for their calculations which results in an hourly CSV file as well as the normal radiation map output.
    - The CSV file is formatted as following: P_x, P_y, P_z, N_x, N_y, N_z, mm-dd hh irrad. ...
    - As a result it has 8766 columns and [number of points + 1] rows.
  • In the load metrics dialog, there is a new button option to 'falsecolor' a climate-based point simulation. If you have run a climate-based metric (illuminance or irradiance), you can visualize the hourly output for a single point with this command.
  • When loading metrics, the maximum and minimum values are now displayed for illuminance, radiation map (nodes), and daylight factor simulations.
  • The Results folder has been renamed to the DIVA folder.
    - A local materials file is created for each project and is stored in .\Filename - DIVA\Resources\material.rad. New materials can be created in this file without changing the main material.rad folder. Re-running the Location command will allow you to reset the local materials file with the main DIVA materials file located at C:\DIVA\Daylight\material.rad.
    - Daylight coefficient files and annual DGP files for Climate-Based Simulations are now stored in .\Filename - DIVA\Resources\. This means that project specific materials and Climate-Based Simulation results can be preserved by moving a Rhinoceros file and DIVA folder to another computer.

New Grasshopper Features

  • The Illuminance and Visualization Simulation now offers an option to have the date/time manually inputted on the grasshopper canvas.
  • The solar position algorithm for all solar tools has been replaced with the one Radiance uses for consistency and accuracy.
  • The Solar Vector (now Sun Path Component) has a menu for inputs. Location can be selected from the current weather file directory or manually inputted on the grasshopper canvas.

Thank you all for using DIVA! We will be updating our documentation over the next few days to reflect these changes.

We just released an updated beta, 2.1.1.1, that fixes a few bugs, most notably:

  • When falsecoloring the annual results associated with a climate-based metric, an upper and lower scale can now be selected. This is helpful for presentations, as seen in the graphic below where each point is analyzed in the range of 300-2000 lx. 
  • Point-in-time glare and node-based irradiation maps using the Daysim climate-based method work again.

As always, the detailed changelog and download is available from the Solemma webpage.
