Dependent domain options for reference fields

When you create a reference field, the options in the Dependent Domain list of the Create Field dialog box depend on the type of result that is displayed in the post view.

Scalar nodal results

When the displayed result is a nodal result for a scalar quantity like temperature, you have two options:

• To create a field that contains the unitless magnitude of the scalar quantity, select Parameter. The software interprets such a field as dimensionless.

• To create a field that contains the magnitude of the scalar quantity and the associated units, select the option that is named for the physical quantity type. For example, if the scalar nodal result is temperature, the option is named Temperature.

Vector nodal results

When the displayed result is a nodal result for a vector quantity like displacement or the magnitude of the vector quantity, you have five options:

1. To create a field that contains the unitless magnitude of the vector quantity, select Parameter. The software interprets such a field as dimensionless.

2. To create a field that contains the magnitude of the vector quantity and the associated units, select the option that is named for the physical quantity type. For example, if the vector nodal result is displacement, the option is named X Axis.

3. To create a field that contains the unitless magnitudes of the components of the vector quantity, select Parameter Space. The software interprets such a field as dimensionless.

4. To create a field that contains the magnitudes of the components of the vector quantity and the associated units, select Cartesian.

5. To create a field that contains the magnitudes of the components of the vector quantity and the associated units, but has different names for the dependent quantities than the Cartesian option, select 3–D General. As a best practice, use the Cartesian option instead.

Vector elemental results

When the displayed result is an elemental result for a vector quantity like heat flux or the magnitude of the vector quantity, you have three options:

1. To create a field that contains the unitless magnitude of the vector quantity, select Parameter. The software interprets such a field as dimensionless.

2. To create a field that contains the unitless magnitudes of the components of the vector quantity, select Parameter Space. The software interprets such a field as dimensionless.

3. To create a field that contains the magnitudes of the components of the vector quantity and the associated units, select 3–D General.

Vector element-nodal results

When the displayed result is an element-nodal result for a vector quantity like grid point force or the magnitude of the vector quantity, you have five options:

1. To create a field that contains the unitless magnitude of the vector quantity, select Parameter. The software interprets such a field as dimensionless.

2. To create a field that contains the magnitude of the vector quantity and the associated units, select the option that is named for the physical quantity type. For example, if the vector element-nodal result is grid point force, the option is named Force.

3. To create a field that contains the unitless magnitudes of the components of the vector quantity, select Parameter Space. The software interprets such a field as dimensionless.

4. To create a field that contains the magnitudes of the components of the vector quantity and the associated units, select the other option that is named for the physical quantity type. For example, if the vector element-nodal result is grid point force, the option is named Component Force.

5. To create a field that contains the magnitudes of the components of the vector quantity and the associated units, but has different names for the dependent quantities than the fourth option, select 3–D General.

Tensor element-nodal and elemental results

When the displayed result is an element-nodal or elemental result for an individual component of a second-order tensor quantity like stress, or a quantity derived from the components of a second-order tensor quantity like von Mises stress, you have three options:

1. To create a field that contains the unitless magnitude of the tensor component or the derived quantity, select Parameter. The software interprets such a field as dimensionless.

2. To create a field that contains the magnitude of the tensor component or the derived quantity and the associated units, select the option that is named for the physical quantity type. For example, if the tensor result is a stress component, the option is named Stress.

3. To create a field that contains the magnitude of all six tensor components and the associated units, select Stress Tensor.
