The two things needed to start this process is a Inventor Part or Assembly file, and some estimated or actual calculated input forces for your part.
Let's start by opening your Inventor part file.
Step 1: Starting a stress analysis
The simple definition of static would be your main input force which is not affected by time/temp/atmospheric pressure. Modal is dynamic forces (vibration) that will have secondary effects on your part.
For this trial we are going to use a static stress analysis. Select it and click OK.
Step 2: Defining your parts material.
Once you are happy with your material and settings click OK and then we will be ready to define our constraints and input forces.
