include gravity concerning elevation geometry

Please login with a confirmed email address before reporting spam

Hi. I'm new to comsol. Now I'm trying to simulate just a simlple mechanical model with ground surface geometry. I want to include the gravity effect to my underground rock mass model but the initial gravity function is considering z coordinate which is not suitable to my model. The point is, that the gravity value in the upper surface of the model should be 0.. I hope someone could give me a solution for this problem. thank you :)
