 Posted: Thu Jun 26, 2014 5:23 pm Post subject: Problem with gyro structure |
 |
|
Hi to all,
i'm trying to design a model of gyro structure with known dimension of global structure and pore size of known diameter (e. g. : parallelepiped of 22*22*36 mm and pore size of 300 micro m)
Could somebody help me? i'm sorry, but i'm new on k3dsurf.
cheers, Marco
ps: What are the X,Y,Z? what i have to put in? thanks |

Hi Marco,
X, Y and Z are the the grid boundaries. In your case,you should probably work with a grid like this:
X = [0, 22]
Y = [0, 22]
Z = [0, 36]
How can we express the pore section in x,y and z terms? is there a formula for this? if yes, you can tweak the Gyroid formula to meet your needs. I'm not sure about that but you will need to calculate a factor f that depend on the pore section formula. Then replace the current Gyroid formula G(x, y, z) by G(f*x, f*y, f*z)
With a non accurate precision, I'll say a grid :
X = [0, 4]
Y = [0, 4]
Z = [0, 4]
will contain a pore section of almost 4 mm, the factor is then: f=(4/0.3)*(22/4)
