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.

Radioss Cards
Radioss allows you to program your own properties, mostly for springs, that can be used in a simulation. Unsupported Radioss properties and user defined Radioss properties are assigned the PROP_UNSUPPORTED card image.
HyperMesh imports unsupported properties with the PROP_UNSUPPORTED card image, and preserves their corresponding IDs and associated components.
In the PROP_UNSUPPORTED card image, all property sub-options, parameters, and data lines are supported as simple text. HyperMesh 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.

| /PROP/TYPE25 (SPR_AXI) | Defines the axisymmetric spring property
set. Note: Block Format Keyword
|
| /PROP/TYPE13 (SPR_BEAM) | A beam type spring property that works as a beam
element with six independent modes of deformation. This spring accounts for
non-linear stiffness, damping and different unloading. Deformation, force and
energy-based failure criteria are available. Note: Block Format Keyword
|
| /PROP/TYPE44 (SPR_CRUS) | A spring element property that represents a simple
macro model of a crushable frame in compression, tension, torsion and bending.
Originally, this element was developed in cooperation with PSA PEUGEOT
CITROËN. Note: Block Format Keyword

| /PROP/TYPE8 (SPR_GENE) | A spring property that works with six independent
modes of deformation. This spring accounts for non-linear stiffness, damping and
different unloading. Deformation, force and energy based failure criteria are
available. The general spring property is often used to model a joint connection
between two parts. Note: Block Format Keyword

| .BPR | Define beam profiles. |
| .ETASHELL | Used to assign the laminate to the elements. The Projection method is supported. |
| .ETASOLID | Used to assign the laminate to the elements. The Projection method is supported. |
| .MCCBUSH | Defines the property on the BUSH element. |
| .PHP SHELL | Assign physical properties to an existing mesh. |
| SOLIDMAT | Assign physical properties to an existing mesh. Note: This is a dummy property
that creates a link between the elements and the material, as it is not possible
to directly assign a material to the elements.
