I find it really difficult and time consuming sometime to find out in what units a measure is given in the creo simulate summary file. Is stress in Pa, kPa, MPa? Is strain energy in J, mJ, kJ and so on. I know this is correlated to the units of the part or assembly but for at least energy it isn't always intuitive how to calculate it. I guess in mmkgs that the energy unit is kg*mm/s^2*mm or micro Joule but I for a while thougth it was Nmm or mJ. Either way it should be really easy to program so that the unit is displayed after the value. I attach a picture to show were I would have wanted it.
