Abstract: We study the numerical behaviour of a particle method for gradient ows involving linear and nonlinear di usion. This method relies on the discretisation of the energy via non- overlapping balls centred at the particles. The resulting scheme preserves the gradient ow structure at the particle level and enables us to obtain a gradient descent formulation after time discretisation. We give several simulations to illustrate the validity of this method, as well as a detailed study of one-dimensional aggregation-di usion equations.
