why doesn't my model roll angle start with zero at the beginning of step steer analysis
Hi! The initialized position and speed of a driven vehicle is calculated before data is recorded. Based on your supplied MDL file, your vehicle's CGY is -1.50729 mm, and thus should have an initialized roll angle. To verify this, you could track roll angle vs. time during a simple simulation where we allow the vehicle to settle under gravity by:
I followed those steps and created the following plot (Capture001.png). Here you can see the roll angle starts at 0 degrees.
Hope this helps!
