New fit option

We have included a new fit option which helps to increase the speed of analysis in time critical applications: In methods which use pre-fit sets in the list of fit parameters you can now include the current fit parameter values in the pre-fit search. This eventually avoids many fit iterations if differences between consecutive measurements are small.

The new feature can be turned on or off in the dialog of fit options.

 

Climate settings, window tilt angle, pane absorption and temperature computations

We have upgraded several CODE functions related to the technical performance of glazing products.

You can now compute solar pane absorption and pane temperatures for up to 6 glass panes.

The list of integral quantities in CODE features new menu items (in File/options):

  • set global climate parameters used for U-value, g-value and temperature computations
  • set the window tilt angle for all U-value, g-value and temperature computations

You can display climate values using labels in a view with the following names:

  • ‘selected_climate’ (shows the name of the climate)
  • ‘selected_climate_parameters’ (shows values of outside temperature, external heat exchange coefficient he, inside temperature, internal heat exchange coefficient, solar power
  • ‘selected_climate_ISO52022’ (shows the name of the climate settings for ISO 52022-3 computations)
  • ‘selected_climate_parameters_ISO52022’ (shows values of outside temperature, external heat exchange coefficient he, inside temperature, internal heat exchange coefficient, solar power, used for ISO 52022-3 computations)

You can display the value of the window tilt angle using a label called ‘window tilt angle’.

Finally, you can call the following new script commands to open user dialogs in the main view:

  • edit climate
  • edit window tilt angle

WOSP-MAC

Multiple angle reflectance measurements

Glass for buildings and cars may have different appearance with respect to color when the viewing angle changes. The angular dependence of color values is important for the design of glass coatings, and hence it is important to verify that the wanted color values are obtained after coating deposition.

WOSP-MAC (multiple angle color sensor) is a lab instrument that measures color values at fixed angles of incidence of 30°, 45° and 60°.

Measurements can be performed using a very simple software interface – they take about 10 seconds.

Results for various samples are collected in a workbook which can be exported as Excel document.

WOSP-ART

Once youhave optimized the design of your coating product with respect to angular variation of color you have to check if it really performs as CODE predicts.

The prototype described in this section will do the job: You can record absolute reflectance and transmittance spectra in high quality for the range 8° to 85° of the angle of incidence. The 85° are possible only for thin samples, with thickness below 5 mm. You do not need a calibration mirror since the 100% reference measurement can be done with light source and detector facing directly opposite to each other.

WOSP-ART consists of a light source and a detector mounted on arms which can be rotated individually. Spectra are recorded for the wavelength range 380 … 1100 nm. Extensions to the UV (down to 280 nm) and the NIR (up to 2500 nm) are possible.

Measurements are performed using our CODE software which can export results to data files or external SQL databases.

Here is a video demonstrating the operation of WOSP-ART.

“The program can´t start because mfc120d.dll is missing “

This problem has been described in a previous post. The recommended installation of the Microsoft redistributable package does not seem to solve the problem in every case.

We have made the missing DLLs available on our website. You can download the files here and copy them to your SCOUT or CODE program folder directly, without executing any installation routine.

The relevant program folders are (very likely) c:\scout\ (in the case of SCOUT) or c:\code\ (for the CODE software).

Poor graphics appearance on some monitors – how to avoid …

On monitors with high dpi values (small pixel size) Windows 10 sometimes decides to scale text output on graphics pages. In this case main view graphics of SCOUT, CODE and BREIN may look ugly, like on low resolution screens.

If this happens on your computer you can right-click the program file (scout.exe, code.exe or brein.exe) and select ‘Properties’ (or ‘Options’) and then open the tab ‘compatibility’. Check the option ‘Disable display scaling on high DPI settings’ as shown below:

high_dpi_settings

That should solve the problem.

Thanks to S. Eraslan for pointing out this solution!
