Topic: gravitational loading (DeadWeight) question
If I want a gravitational force to act in the negative y-direction, does that mean that the acceleration component in the DeadWeight declaration should be positive (as in other codes) or negative? I'm a little confused given the DeadWeight class definition that says the acceleration components are expected to be downwards vertical.
Can you clarify the sign convention for me? In searching through other posts I've seen what looks like gravitational loading values specified both positive and negative.
Thanks in advance.
