Animation

The Animation Probe tool is used to visualize the time domain evolution of electric or magnetic fields evaluated on a specific surface(s) of the model. The animation is visualized directly in the EMA3D GUI.

Instructions

  1. ClickAnimation Image 16 Animation within the Probes section under the EMA3D tab in the ribbon.

    2. animation probe 1

  2. In the Properties Panel, adjust the probe properties as desired.

    3. animation probe 2

  3. Using the select surfaceSelect Surface Image 16 tool, select the surface(s) to probe. The surface(s) can be selected in the model window or within the structure tree. The selected surface(s) will turn yellow.

    4. animation probe 4

  4. Click OKCheck Image 16 to complete the probe definition.

  5. Adjust the definitions of the probe at any time by right clicking it within the Simulation Tree and selecting Edit from the pop-up menu.

  6. Note that there is a maximum output of 500 frames for the Animation probe. Therefore, once the user starts the model pre-processing using the StartStart Simulation Image 16 button, a warning may appear reading Maximum Number of Output Samples Exceeded. EMA3D will adjust the Animation probe time step to ensure that the 500 frame threshold is met. Alternatively, close out of the warning and manually change the Step or Skip value in the probe properties panel. Then restart the simulation.

Entry

Meaning

Name

Name of the probe.

Probe Type

The field to measure. It can be set to Electric Current, Normal Electric field, Magnetic Current, Normal Magnetic field, air conductivity, spatial charge, or absorption rate

Direction Override

Override probed direction.

Time

Entry

Meaning

Start - Match Domain

Match the start time to the FDTD domain.

Start - Value

The probe start time.

Step - Match Domain

To which domain to match the probe time step:

  • Highest Frequency sets the probe time step such that it captures up to the highest supported frequency of the domain (this time step is coarser than the Domain time step and results in smaller files)

  • Time Step matches the probe time step to the FDTD domain time step

  • False allows the user to set the probe time step value manually

Step - Value

The probe time step.

End - Match Domain

Match the end time to the FDTD domain.

End - Value

The probe end time.
