We develop an Euler-type particle method for the simulation of a McKean–Vlasov equation arising from a mean-field model with positive feedback from hitting a boundary. Under assumptions on the parameters which ensure differentiable solutions, we establish convergence of order \begin{document}$ 1/2 $\end{document} in the time step. Moreover, we give a modification of the scheme using Brownian bridges and local mesh refinement, which improves the order to \begin{document}$ 1 $\end{document} . We confirm our theoretical results with numerical tests and empirically investigate cases with blow-up.
