Settings

License Type

Ansys HPC users can set this parameter to "Pool" or "Pack" based on their parallel license. Other users can ignore.

Launch EMA3D

Whether to open the EMA3D and MHARNESS tabs, which will use an EMA3D license, every time Discovery is opened ("Always") or never when Discovery is opened ("Never"). "Default" is whichever of the two choices was selected during installation. Opening with the EMA3D icon will always open the EMA3D and MHARNESS tabs.

Automatic Harness Packing

Whether to pack the harness every time it is modified. Checking the box will pack the harness every time it is modified. Unchecking the box will only pack the harness during the harness export. This option is useful for harnesses with many cables that can take a longer time to pack.

Field Probe Band Width Running Average

(CHECK THIS) This parameter changes the size of the bandwidth average. For calculating the electromagnetic fields and the transfer functions, EMA3D can perform a 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. The default value is 0%, indicating that EMA3D does not by default compute a bandwidth average.

MHARNESS Simulation Type

"Integrated Co-simulation with EMA3D" will run MHARNESS and EMA3D coupled together. "Standalone MHARNESS Simulation" will only run the MHARNESS simulation.

Precision

Whether the solver should use "Single" (32 bit numbers) or "Double" (64 bit numbers) precision. Double may take longer to run.

Prevent Sleep

Checking the box will stop the computer from going into sleep mode while a simulation is running.

Nexxim Viewing Resistance

Default value of 1 mΩ. In general, users should not and will not need to adjust this value. In MHARNESS Nexxim simulations, only voltages are directly measured. To obtain currents, a small "viewing" resistor with a value of 1 mΩ is inserted into the port. Importantly, the viewing resistance needs to be much lower (on the order of 100x) than the circuit impedance (most realistic circuits will already have a larger value). If the characteristic circuit impedance is on the order of 1 mΩ, users can reduce the viewing resistance value, though it can never be smaller than 1e-5 Ω.

Interpolate *.TS Files

Whether to interpolate the output of the .TS file for S parameter simulations.

Number of *.TS File Frequencies

Set the number of frequencies to output to the .TS file for S parameter simulations. Default value is 250.

Interpolation Type

Whether to use linear or logarithmic interpolation between frequencies written to the .SNP file for S parameter simulations.

Limit Maximum Frequency

Whether to limit the maximum frequency output of the .SNP file for S parameter simulations.

Maximum Frequency

The greatest frequency that will be written to the .SNP file for S parameter simulations. All frequencies above this limit will not be output to the .SNP file and a new S parameter simulation will need to be run to generate S parameter results above this limit.

Render Elements After Mesh

Toggles whether the mesh should be rendered after meshing is complete.

Render Element Edges

Toggles whether rendering should show black edges around mesh elements.

Single Color Mesh

Toggles whether mesh rendering colors should be based on the material color or if all geometry should be colored using Default Mesh Color.

Default Mesh Color

The color of the mesh when material definitions are turned off or Single Color Mesh is selected.

Allow Mesh Transparency

Toggles whether mesh elements can be drawn transparently (depending on the surface color), otherwise elements are always opaque.

Deconfliction Type

• "None": no deconfliction for cable meshes (except within a single line)

• "Cable Only": cable meshes attempt to avoid meshing into other cables (except at endpoints)

• "Avoid all Surfaces": cable meshes attempt to avoid mesh conflicts with surfaces (except at endpoints)

• "Bulkhead Routing": line meshes attempt to avoid consecutive mesh conflicts with meshed surfaces by passing through meshed surfaces at right angles

Improved Surface Connectivity

Provides surface level post-processing for surface meshing that improves the connectivity within meshed surfaces by reducing the occurrence of gaps and misaligned surface elements.

• Note: though connectivity is improved within each individual surface, connectivity at the interfaces of separate surfaces is not addressed by this feature and could change as compared to legacy behavior. Users should check their meshes to ensure that connectivity between surfaces is acceptable. This feature can be disabled to return to legacy surface meshing behavior by unchecking the "Improved Surface Connectivity" box.

• Additionally, this update can be applied selectively to different surfaces by the following procedure: users can mesh surfaces, change the meshing option in the setting menu, and then right click on the surface selecting mesh to re-mesh that individual surface with the new mesh settings. This allows for selectively meshing surfaces with the options that are best for that surface.

Surface Interface Smoothing

Smooth meshed boundary of coincident surfaces by removing overhanging surface elements (re-mesh required for settings to apply).

• Note: while the algorithm improves surface mesh quality in many cases, performance may vary from model to model. The user should always visually inspect their mesh to ensure compliance with their requirements.
