I have just discovered a neat extra in Simulation 2012 that is not described in any of the 'What's New' literature - but could save you time.
In a nonlinear study there is often a need to report the Reaction Forces across all the time steps. For instance if you were to deform a rubber bushing by applying a prescribed displacement you might want to know how much force needs to be applied at each step - and preferably plot this on a graph. In 2011 this could not be done directly. You needed to use 'List Result Force', pick 'Update', write down the value and step through each time step. In 2012 this is dead easy - just pick the 'Response Graph' button and you get the forces plotted on a graph.
