How to include the restart in python

Save

With these sentences the model is saved in each step while you print the results

       serializer = Serializer("cantilever3d" + str(step))
       serializer.Save("StructureModelPart", model_part);
       serializer = 0

Load

You need to put these sentences before to read a model

       serializer = Serializer("cantilever3d" + str(step))
       serializer.Load("StructureModelPart", model_part);
