Introduction

The Statistics tab page gives information on the solve time and speed. The Tags on the Statistics page are slightly different for Steady State and Dynamic projects, they will be documented in two separate tables:

The memory section is common to both Steady State and Dynamic Projects and is shown in a separate Memory Table after the Dynamic table.
