The intellectpsim.ddi file contains the properties of Intellect Axxon PSIM's main objects. For your own objects, we recommend creating a separate file, intellectpsim.xxx.ddi, where xxx is a unique part of the filename. By using a separate file, you avoid double inclusion of the properties after an update of the Intellect Axxon PSIM software package. On startup of the software package, the DDI files are merged.
If an object is duplicated in several ddi-files, then at Intellect Axxon PSIM software startup the properties of the object from the last file are applied in accordance with the sorting of files by name. For example, if an object is described in files intellectpsim.xxx.ddi, intellectpsim.xxx1.ddi and intellectpsim.xxx2.ddi, the properties from the intellectpsim.xxx2.ddi will be applied.
