E

The electric field, E

E_t

Transient electric field, E.

H

The magnetic field, H

H_t

Transient magnetic field, H.

Jvol

The volume current density, J_vol

Jsurf

The surface current density, J_surf

Jsurf_t

Transient surface current density.

Poynting

The Poynting vector, defined as 0.5E x H*

Poynting_t

Transient Poynting vector.

LocalSAR

The local Specific Absorption Rate

AverageSAR

Peak spatial average SAR, dependent on the Average SAR Method chosen in the Specific Absorption Rate Setting.

Certification SAR

IEEE standard Specific Absorption Rate certification number. (See Modifying SAR Settings and Calculating the SAR.)

To calculate certification SAR on a specific object (rather than the whole model) proceed as follows:

1. In the Calculator Input area, click the Quantity button and select Certification SAR.

   Certification SAR is displayed in the calculator stack.

2. In the Calculator, click the Geometry button.

   The Geometry dialog box displays with the Volume radio button selected and the available geometries listed.

3. Select the Geometry of interest.

   This enables the OK button.

4. Click the OK button.
5. This adds the selected Volume geometry to the calculator stack.
6. In the Calculator Output area, press the Value button.

   This prepares the calculation for the selected quantity and volume.

7. Press the Eval button to evaluate.

   Both the value and location will be shown on the calculator stack.

SurfaceLossDensity

This contains the surface impedance (if any) loss at every node in every triangle. This is calculated as:

where p_sis the surface impedance loss density, S is the Poynting vector on the boundary, and n is the out unit normal of the boundary.

To export a REG file containing the surface loss density, place the SurfaceLossDensity in the top register and use the Write... command, selecting Reg format.

VolumeLossDensity

The volume loss density p is calculated as:

where E is the electric field, is the conjugate of the volumentric current density, B is the magnetic flux density, and is the conjugate of the magnetic field.

To export a Reg file containing the volume loss density, place the VolumeLossDensity into the top register, and use the Write....command, selecting the Reg format.

VolumeLossDensity_t

Transient volume loss density, calculated as:

0.5 * Re(E * J)

SurfaceForceDensity

Surface Forces exist when one side is conductor, but the other is not, or finite conductivity and layered impedance boundary. This is mainly for the purpose of mapping surface force density in HFSS to Workbench Mechanical. For details on the calculations, see the technical notes.

Temp

Temperature.

Displacement

This is value is for use with Workbench when exploring stress feedback.
