Cannot place line as a voltage sensor

[Byron van Vugt]

Hi

I've moved to a new computer with a new install of Sim4Life. On prior models this was not an issue, but I now seem unable to drag and drop (Or find an alternative method) for placing a modelled line as a voltage sensor within the model.
No error shows up, just nothing happens.

Cheers,
Byron

What version is this happening in? Does Sim4Life show a little circle slash icon when you try to add it?

[Byron van Vugt]

Hi Brown, Its Version 8.0.0. The drag and drop appears as if it is going to work (no circle slash indicating I cannot place the line within the sensor) but the line is not associated with the sensor following the drag-drop process.
Has the process for associating a line to a voltage sensor changed without any change in the user manual, or is this a bug? If a bug I will look to reinstall Sim4Life as an attempt to remedy it.

It looks like this is a bug. Until it is fixed, you can still add line sensors to LF simulations using the API.

Here is a quick example that adds an entity named 'Lines 1' as a voltage sensor:

# -*- coding: utf-8 -*-

import numpy
import s4l_v1.document as document
import s4l_v1.materials.database as database
import s4l_v1.model as model
import s4l_v1.simulation.emlf as emlf
import s4l_v1.units as units
from s4l_v1 import ReleaseVersion
from s4l_v1 import Unit


# Define the version to use for default values
ReleaseVersion.set_active(ReleaseVersion.version8_0)

# Creating the simulation
simulation = emlf.ElectroQsOhmicSimulation()

# Mapping the components and entities
component__plane_x = simulation.AllComponents["Plane X+"]
component__plane_x_1 = simulation.AllComponents["Plane X-"]
component__background = simulation.AllComponents["Background"]
component__plane_y = simulation.AllComponents["Plane Y+"]
component__plane_y_1 = simulation.AllComponents["Plane Y-"]
component__plane_z = simulation.AllComponents["Plane Z+"]
component__plane_z_1 = simulation.AllComponents["Plane Z-"]
component__overall_field = simulation.AllComponents["Overall Field"]

entity__line = model.AllEntities()["Lines 1"]

# Adding a new VoltageSensorSettings
voltage_sensor_settings = emlf.VoltageSensorSettings()
components = [entity__line]
simulation.Add(voltage_sensor_settings, components)

# Editing AutomaticGridSettings "Automatic
automatic_grid_settings = [x for x in simulation.AllSettings if isinstance(x, emlf.AutomaticGridSettings) and x.Name == "Automatic"][0]
components = [entity__line]
simulation.Add(automatic_grid_settings, components)

# Editing AutomaticVoxelerSettings "Automatic Voxeler Settings
automatic_voxeler_settings = [x for x in simulation.AllSettings if isinstance(x, emlf.AutomaticVoxelerSettings) and x.Name == "Automatic Voxeler Settings"][0]
components = [entity__line]
simulation.Add(automatic_voxeler_settings, components)

# Update the materials with the new frequency parameters
simulation.UpdateAllMaterials()

# Update the grid with the new parameters
simulation.UpdateGrid()

# Add the simulation to the UI
document.AllSimulations.Add( simulation )
