1 - Creating the geometry |
| |
|
|
 |
Create an initial approximation of your structure
using NURBS!
|
|
- Even pretty rough approximations are generally good enough.
But keep in mind that the closer your guess is to the final solution,
the less the computer has to work afterwards.
- This is an "all Rhino 4.0" step.
|
 |
| |
|
|
|
|
Convert the NURBS representation of the
initial geometry to mesh objects
|
|
- Rhino Membrane works only on polygonal faces, as they offer
more geometrical possibilites than NURBS (especially for highly irregular structures).
- You can use the Rhino command "_Mesh" for this task.
"Membrane = Polygonal mesh (triangles, quads, mixed meshes)"
"Cables, Trusses = Lines, Polylines"

4 - Checking the results |
| |
|
|
|
Display the actual membrane stresses
|
|
- The stresses are not displayed in wireframe mode (switch to render).
- You can visualize the stresses in warp and weft direction.
These directions are defined according to the
U- and V-mapping coordinates.
|
 |
| |
|
|
|
|
Display the reaction forces (version 1.2 and above)
|
|
- Choose the option "Reaction" in the "Stress plot" menu.
- You can change the direction of the force vectors in the option menu.
|

5 - Creating a new problem |
| |
|
|
|
Initialize the problem data
|
|
- In order to clear all data of the previous calculation, click on.
- Of course, starting a new file will do the clearing as well.

|
|
Becoming familiar with the program
|
|
Once you understand the basic concepts of Rhino-Membrane, try more advanced
structures. Especially the combination of form finding elements with elastic trusses
provides a huge number of interesting possibilites (tensegrity, hybrid structres, etc.)
