1. An ablation system comprising:
an energy generator configured to generate ablation energy;
an ablation catheter in communication with the energy generator and including a plurality of electrodes; and
one or more controllers in communication with the energy generator and configured to:
generate a graphical representation of the plurality of electrodes of the ablation catheter for displaying via a graphical user interface (GUI);
designate, via the GUI, at least some of the plurality of electrodes to be active electrodes;
designate the active electrodes as a source electrode or a sink electrode, wherein at least two or more of the active electrodes being designated as source electrodes and at least two or more of the active electrodes being designated as sink electrodes;
assign an amount of power to each of the designated source electrodes;
estimate an amount of power associated with each of the designated sink electrodes based at least in part on the assigned amount of power of each of the designated source electrodes and based at least in part on distances between the designated source electrodes and the designated sink electrodes;
make a determination that the estimated amount of power associated with at least one of the designated sink electrodes is above a threshold; and
disable an ablation-initiation button on the GUI in response to the determination.
