A laser wakefield acceleration (LWFA) model has been upgraded to better predict the outcome of experiments to test two new LWFA techniques. The first method is seeded self-modulated LWFA where an ultrashort electron bunch acts as a seed to create a wakefield in a plasma, which is subsequently amplified by the laser pulse. The second scheme is pseudo-resonant LWFA where nonlinear pulse steepening of the laser pulse by the plasma allows generation of a significant wakefield. A witness bunch that probes the wakefield was incorporated in the model. The model was also exercised to examine new operational regimes currently available during the experiments.
