Thermostat Operators

♨️ Thermostat

sim_add_thermostat_operator(ctx, field, opts)

Regulate kinetic energy toward a target.

• mode (enum): soft_lambda (default), add, mult, none.
• E_target (≥0, default 1.0): target energy.
• lambda_base (default 0): baseline lambda.
• lambda_soft_gain (≥0): feedback gain for soft_lambda.
• lambda_min / lambda_max: clamps applied to lambda.

Examples:

sim.sim_add_thermostat_operator(ctx, field, {
    E_target = 1.5,
    mode = "soft_lambda",
    lambda_soft_gain = 0.2
})

sim.sim_add_thermostat_operator(ctx, field, {
    mode = "add",
    lambda_base = 0.1,
    lambda_min = -2.0,
    lambda_max = 2.0
})
