The properties available to use in a selection project are dependent on the data table and subset currently used in the project. Material properties are grouped together into layouts, based on which material class those properties apply to. Each material subset has a pre-defined layout of selection properties associated with it.
In MaterialUniverse, all datasheets contain values for properties in the standard property set. These properties are common to all materials, and are included within all layouts. Materials in certain subsets contain additional properties that apply only to that material class. For example, the elastomer subset contains the property tear strength, and stainless alloys subset contains Hardness – Rockwell C.
Not all properties will be available in a selection project, depending on which subset and property layout you are using. To use a class-specific property in a selection project, you need to select a subset that contains that property in its list of selection attributes.
Alternatively, you can create a custom subset, and specify the materials and the selection attributes to use in the project.
If you cannot find the property you are interested in using in the selection project, it could be a class-specific property. These properties are only available within certain subsets and databases.
If you know which subset the property is included in, and you only want to compare materials from one material class, you can select a pre-defined subset from the choice in GRANTA EduPack.
If you don't know which subset the property is included in, or you want to compare materials from different material classes, you can create a custom subset.
Records that have no data for a property included in a selection stage are set, by default, to fail that stage. If you want to compare materials from different classes, you need to change the setting to "Pass records with no data":
