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.

 

Thickness fits: Automatic slider range

Starting with object generation 4.77 you can generate low and high limits for fit parameters automatically when you generate them – at least for thickness values. In the fit options dialog (File/Options/Fit) you can set a percentage (lower right corner) which is used to compute the low and high limit of the available thickness range. The reference value is the thickness value at the time the new fit parameter is generated.

Note that the automatically generated range is also the range of parameter sliders that are based on fit parameters.

Note also that you can automatically generate thin film thickness values as fit parameters by drag&drop of a layer stack to the list of fit parameters in the treeview. If the list of fit parameters is shown in a view this is certainly the fastest way of generating thickness sliders.

Here is an example showing sliders with limits of +/-5% that have been generated automatically:

“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).

Bugfix master model

With version 4.56 we have removed a bug in master models for optical constants. Saving a successful model and re-loading it could lead to a strange mix-up of parameter values in some situations, leaving the poor user with a useless configuration. We recently taught CODE and SCOUT to correctly count master and slave parameters – saving and loading should work now.

MSVCP120.DLL is missing …

If you try to run CODE, SCOUT or SPRAY with object generation 4.50 or higher and you get this message please install the Visual C++ Redistributable package for Visual Studio 2013. Here is the link:

If you follow the ‘Download’ section you have to select the vcredist_x86.exe. Running this will install the required DLL files.
