Hello all, I shall be thankful if someone could tell me in details how to use 'save()' and 'load()' functions to save and load triangulation information and the nodal values of displacements, strains, stresses, and may be temperature (similar to step44) so that they can be used as initial data in another simulations with the identical triangulation data.
Or if there is some other simpler way. Thanks and regards, Anup.
