Why running empty Flexsim model uses almost 100% of processor

If someone has been wondering why Flexsim uses almost 100% of a processor core even when running an empty model. See the answer from Phil at Flexsim below.

Hopefully this knowledge pleases some other curios minds

FlexSim will use as much processing power as your computer will give it to run the simulation model, regardless of the model run speed.

This will not adversely affect the performance of other applications running on your computer. If other applications want processing power, then Windows will give it to them, and FlexSim will use less.

While FlexSim is running the model, the Windows task manager will show its usage at approximately 1 core of your processor. If you have a 1-core processor, it will show about 99%. If you have more cores, it will show a lower percent.
