Drawing Curve by (R & ) and applying

self weight : page 21 in the brochure


This is important thing we must

do, Changing Job Name is the

better way to save our work later

without any problems.

Enter the Job Name you want. And

Pick Yes for new Log error file this

is good for Session Editor.

Hint: Sometimes, some windows

disappear, so click on this icon


Change to Global Cylindrical , the

Ansys now understands that we

want work with ( R and )


Preprocessor:

Choosing structural to

update all mechanical

and physical properties

such as Loads, stresses ..

etc.


Select Shell (3D 4node 181) , or

Solid (Brick 8node 185) and NO

Real Constant needed.


Enter material properties

and Density if available


Enter Thickness = 3 then

OK


R

0 0

25 50

25 90

Enter keypoints as in the

fig.


You will get this.


Draw an Arc (By End KPs & Rad)

select keypoints 2 and 3 , then

Apply.

This is useful Command Bar,

you can read and Apply.


Now pick keypoint 1 then OK,

enter the radius of curvature as in

the fig.


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.


You will get new keypoint


Create a straight Line from keypoint 2

to keypoint 4, this is equal to 50 ft.

as in the problem.


Extrude Along Lines, select Curve then

Apply


Now select Line (Path) then OK


Complete Meshing, manual Size as

in the fig. first select long Lines.


Now select short Lines


Apply Mesh (3 or 4 sided)


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


We get like this


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


Pick On
