We discuss various density estimation techniques to represent charge particle distributions in beam dynamics simulation codes. A detailed analysis of the different methods shows that for an accurate, reliable and efficient modeling of microbunching instability a careful control of numerical noise is required. In particular, we compare a standard particle-in-cell scheme plus denoising via wavelets thresholding with a meshless Monte-Carlo method used in statistical estimation. We inplement them in a Vlasov-Maxwell solver and show results for FELs systems.
