I have a I-DEAS UNV file which contains several datasets 55/56/57 of results.
For a given type of result -let's say displacements, stored as dataset 55-, I have several datasets corresping to different timesteps (non linear analysis)
I import the nodes&elements in a fresh new simulation (File > Import > NewSimulation), then the results (Postprocessing navigator - Imported Results > Import Results)
Q1: only result at nodes (dataset 55) are imported
Q2: for each type of result, only the latest one -i.e the latest timestep- is imported
