For Curve Extrusion we must plot
another keypoint then draw
another Line. Press here to change view this is
important in the (R & ) drawing
See here (R=25), (=50), and (Z= -50)
because of Z represents the depth.

Apply Displacement
Constraint for this side
according to our problem
Then repeat the procedure for other
sides also according to our problem
because we have different constraints
22 | Haydar Alsalami \ JNTUH \ India mobile: 00919059070644 – Iraq mobile: 009647801518389 E-Mail: [email protected]

23 | Haydar Alsalami \ JNTUH \ India mobile: 00919059070644 – Iraq mobile: 009647801518389 E-Mail: [email protected]
Inertia – Gravity – Global, enter Global for Y = 9.81 (which is the earth gravity) in this
case the Ansys understands that we want the weight of Curvature applied
See in this window there is gravity with X,Y and Z : for X and Y these uses in such cases
like for Aerospace with planet, here we select with Y that is mean downward to earth.
Pick OK
