We present the latest results in our ongoing work to construct a generalized analytical flux rope model. Our previously published writhed flux rope model is extended to include non-circular cross-sections to better mimic the magnetic field measurements that are seen in situ and imaging observations. We implement our new model within the scope of a fast forward simulation model that propagates a flux rope away from the Sun into the heliosphere and can generate synthetic magnetic field measurements at arbitrary positions. This flux rope is continuously deformed along its axis due to interaction with the ambient solar wind which is provided by other models. We use our model and the forward simulation in an attempt to reconstruct the global picture of a particular multi-point ICME event.
