error for numeric value in until_after_sources list

[leSemaleon]

I want to use multiple conditions to end the simulation. The documentation supports a list of conditions.

I tried using the following code to start the simulation:

sim.run(until_after_sources=[
                           mp.stop_when_fields_decayed(10, field_component,
                                                      mp.Vector3(0, 0, sz/2-dpml-0.5*dAirOut),
                                                      accuracityOfDecay), 
                           10000
                           ]
       )

But it returned the error "'int' object is not callable."

TypeError: 'int' object is not callable

If I move the condition with the number up, the error disappears and everything starts as expected.

sim.run(until_after_sources=[10000,
                           mp.stop_when_fields_decayed(10, field_component,
                                                      mp.Vector3(0, 0, sz/2-dpml-0.5*dAirOut),
                                                      accuracityOfDecay), 
                           ]
        )

Can you show the full error message with a stack trace? This line is suppose to convert the number into a callable function, so I'm not sure where the error is happening:

meep/python/simulation.py

Lines 2809 to 2816 in 0b21c67

	if isinstance(cond[i], numbers.Number):
	stop_time = cond[i]
	t0 = self.round_time()
	def stop_cond(sim):
	return sim.round_time() >= t0 + stop_time
	cond[i] = stop_cond
