Properties

Property entities define and store 1D, 2D, and 3D property definitions for a model.

Properties do not have a display state in the modeling window. You can color the model according to the colors assigned to each property, which is based on element property relationships, by changing the color mode to property.

Element property relationships are dependent on the solver interface. In general, when a component is assigned a property, that property assignment is applied to all elements collected by that component. The method of assigning properties at the component level is therefore referred to as indirect property assignment. Direct property assignment is performed directly on the elements themselves, typically via a property assignment. Direct property assignments always take precedence over indirect property and material assignments.

In the PROP_UNSUPPORTED card image, all property sub-options, parameters, and data lines are supported as simple text. Engineering Solutions does not check the validity or syntax of any data in this mode. You must manually check the validity of the data. No editing, updating, or review of the property data is intended. Also time step calculation and mass calculation are not available for the component that refers to this property.
