Sources

Volumetric sources

Volumetric sources can be set in a simulation by using the festim.Source class.

import festim as F

my_model = F.Simulation()

my_model.sources = [
    F.Source(value=1e20, volume=1, field=0),
    F.Source(value=1e19 * F.x, volume=2, field=0),
    ]

For more information, see festim.Source.

Implantation flux

Hydrogen implanted in a material can be simulated by a Gaussian-shaped volumetric source with the festim.ImplantationFlux class.

import festim as F

my_model = F.Simulation()

my_model.sources = [
    F.ImplantationFlux(
        flux=1e20,
        imp_depth=1e-9,
        width=1e-9,
        volume=1,
        ),
    ]

This class is used in this tutorial.

Radioactive decay

Radioactive decay can be simulated by a volumetric source with the festim.RadioactiveDecay class.

import festim as F

my_model = F.Simulation()

my_model.sources = [
    F.RadioactiveDecay(
        decay_constant=1.78e-9,
        volume=1,
        field="all",
        ),
    ]
