Create Geometry in GAMBIT
Start GAMBIT
Create a new directory called cylinder and start GAMBIT from that directory by typing gambit -id cylinder at the command prompt.
Under Main Menu, select Solver > FLUENT 5/6 since the mesh to be created is to be used in FLUENT 6.x.x version.
Operation Toolpad > Geometry Command Button > Vertex Command Button > Create Vertex
Create the vertices as listed in the following table. Again, the units can be arbitrary, and you may scale the lengths proportionally.
Label | X | Y | Z |
A | 0 | 0 | 0 |
B | 0.5 | 0 | 0 |
C | 0 | 0.5 | 0 |
D | -0.5 | 0 | 0 |
E | -5 | 0 | 0 |
F | -5 | 5 | 0 |
G | 0 | 5 | 0 |
H | 20 | 5 | 0 |
I | 20 | 0 | 0 |
J | 20 | -5 | 0 |
K | 0 | -5 | 0 |
L | -5 | -5 | 0 |
Operation Toolpad > Geometry Command Button > Edge Command Button > Create Edge
1.Create circle
Right click Create Edge button, then choose Create Full Circle. Choose A as Center, B and C as End-Points, click Apply then we get circle ABC.
2.Split the circle
Choose Split/Merge Edges. Choose circle ABC for Edge box, and select Split With: Vertex.
Then choose vertex D as reference vertex, click Apply. Then circle will be split to two parts: BCD and BMD.
3.Create the straight line.
Under Edge, choose Create Straight Edge: D and E, E and F, F and G, G and H, H and I, E and L, L and K, K and J, J and I , then B and I.
Operation Toolpad > Geometry Command Button > Face Command Button > Form Face
Right click and choose Create Face from Wireframe.
Choose Edge DE, EF, FG, GH, HI, IB, and BCD to create face1. Similarly, choose DE, EL, LK, KJ, JI, IB and BMD to create face2.
Go to Step 2: Mesh Geometry in GAMBIT.
