Question

Hello, 
 im trying to do static drift case condition, 
 1. in tutorials it was saying tx imposed with acceleration ramp and ty imposed with drift angle, but my doubt is how should we imply drift angle. 
 2. can you please share the formulae for implying drift angle and should we give the value deg or radians. 
 Thank you

Oh I see, thanks. In that case, what we propose is the following: for a static drift, the ship does not have to rotate around its gravity center. However, it is moving in X and Y directions. That's the way to impose an angle with the flow. In terms of values, you should not impose an angle such as degree or radian but knowing the angle with the flow and the speed in X direction, you can compute the required velocity in Y direction, that will be imposed through Ty. You can impose the same ramp duration for both Tx and Ty. I hope I was clear enough. 
 Best regards,
