How to get electric field at certain CartesianPoint

[rajxabc]

Hi ,
How to get_electric_field at random cartesian point
For example
calculate_electric_field!(sim)
cpt = CartesianPoint(0,0,0)
E = get_electric_field(cpt)
?
Thanks

The way we do it in the charge drift is using an interpolated electric field.

SolidStateDetectors.jl/src/ElectricField/ElectricField.jl

Lines 208 to 210 in e68da8b

	function interpolated_vectorfield(ef::ElectricField)
	interpolated_vectorfield(ef.data, ef.grid)
	end

SolidStateDetectors.jl/src/ChargeDrift/ChargeDrift.jl

Line 105 in e68da8b

step_vectors[n] += get_velocity_vector(electric_field, _convert_point(current_pos[n], S))

So, I’m not on my computer right now, but something along the lines

ef = SolidStateDetectors.interpolated_vectorfield(sim.electric_field)
result = SolidStateDetectors.get_velocity_vector(ef, CartesianPoint(pt)) # or CylindricalPoint, if sim is on a Cylindrical grid
