Electrodes
This is an overview about the electrode models used for simulation. Each
electrode model defines the geometry (tip, contacts, shaft) and default
dimensions. The electrode is placed in the simulation domain via
TipPosition, Direction, and Rotation[Degrees] in the JSON input.
Custom electrode parameters
Every electrode model has a corresponding parameter class that defines its
geometric dimensions (tip length, contact length, contact spacing, lead
diameter, total length, etc.). To modify these dimensions, append Custom
to the electrode name and provide a CustomParameters dictionary:
{
"Name": "BostonScientificVerciseDirectedCustom",
"CustomParameters": {
"tip_length": 1.5,
"contact_length": 1.5,
"contact_spacing": 0.5,
"lead_diameter": 1.3,
"total_length": 450.0
},
"Rotation[Degrees]": 0.0,
"Direction": {"x[mm]": 0.0, "y[mm]": 0.0, "z[mm]": 1.0},
"TipPosition": {"x[mm]": 0.0, "y[mm]": 0.0, "z[mm]": 0.0}
}
The available parameter names depend on the electrode model. Common parameters
across most models include tip_length, contact_length,
contact_spacing, lead_diameter, and total_length (all in mm).
See the API reference for each electrode’s parameter class.
Note
When using the standard (non-Custom) electrode name, default dimensions are
used and CustomParameters is ignored.

Note
The total length does not influence the computational domain; therefore, the above electrodes are modeled at 400 mm.
