zone property command
Syntax
- zone property s a... <range>
Make a constitutive model(s) property assignment. The name of the property is s and the value being assigned to it is a. The assignment will affect any zone whose constitutive model includes the property named (noting that some properties, such as bulk, for instance, appear in many consitutive models). Limiting a property assignment to zones that have a particular constitutive model assignment is done using the
range
component of the command. For instance, in the following:zone property bulk 3000 range cmodel mohr
the
range
component limits the bulk property specification to zones with a Mohr-Coulomb (mohr) constitutive model assignment.Setting Density
Density, uniquely among the material properties, is not bound with the constitutive model, but is also set with the zone property command as follows.
- density f <range>
Set mass density of zones in the range. This property is not reset when a change is made to the constitutive model assigned to the zones. Note that density may also be set with the command
zone initialize density
.
Models and Properties
All constitutive models have properties associated with them.
There are 19 basic mechanical constitutive models in FLAC3D (not including null, which does not appear below) and 11 option-specific mechanical models. All are classified as follows: elastic, elastic-plastic, dynamic, creep, thermal.
