No simlog variable for power loss analysis

I am trying to estimate the dissipated power in the rectifiers and converters in my Simulink model. I have removed all algebraic loops and get no errors (only 3 warnings) when I run sim(model). I have all of the right settings for simulation data-logging and the sim command definitely simulates the model. However, at the end of it there is no simlog variable in my workspace. I have tried to use the command line to view it and that returns 'undefined function or variable'. My Matlab version is R2016b. Please let me know if there is something I'm missing that's causing this.

Thanks
