Boxed Region

The Boxed Region field probe is a powerful tool with inherent algorithms to process data and record the data in a useful and common format. Boxed Region field probes encompass and process data from many mesh nodes within a volume in the geometric model specified by the User to capture both peak and null features of electromagnetic fields, which could be missed when using data from a single node.

For calculating the electromagnetic fields and the transfer functions, EMA3D performs a 5% running bandwidth average on the field data. Then, EMA3D performs a Fast Fourier Transform of each location and averages the raw values together. Finally, EMA3D then performs another pass and "smooths" them out by averaging neighboring frequencies together with a sliding window.

Instructions

  1. ClickField Probe Image 16 white Field within the Probes section under the EMA3D tab in the ribbon. Then select Boxed Region from the drop-down menu.

  3. Two options for setting the probe will appear in the top left of the model window. The top, default optionDrag Box Image 16 defines the integration boundaries of the field probe using a drag box with directional arrows. The second optionSelect Body Image 16 defines the integration boundaries of the field probe based on a selected body.

  5. Boxed Region probes can also be set to encompass structures. To set a probe using this method, click on the Select BodySelect Body Image 16 tool in the top left of the model window and then select a component in the structure tree or directly in the model window. The structure will be highlighted when hovered over.

Entry

Meaning

Match Domain

Match the start time to the FDTD domain.

Value

The probe start time.

Match Domain

To which domain to match the probe time step: Domain matches the probe time step to the FDTD domain time step. 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). False allows the user to set the probe time step manually.

Value

The probe time step.

Match Domain

Match the end time to the FDTD domain.

Value

The probe end time.
