Hi, Can I parametrize a geometric parameter in a 3D model of v 4.0a? Thanks.

Hi Ivar,
Thank you for your prompt answer. I ment to ask if I can do a parametric sweep of a geometric parameter. Is there a tutorial model doing this on v. 4.0a?
Yours, Fernando.

Hi

there is no model I know about in 4.0a, but it is straightforward:
1) make a 2D structural stationary model
2) define a parameter Th = 0.01[m]
3) draw a rectangle let us say 1m in x, and "Th" in Y
4) add a Fixed constraints on boundary 1
5) add a Body load Fy = -g_const*solid.rho
6) go to the Study node and add a "Parametrical" sweep (not the continuation inside the stationary, as that one does not loop around the geoemtry)
7) define the variable Th (use he "+")
8) define a range 0.01 0.02 0.03
9) Solve

It should work

Hi Ivar,
It worked, I could make the geometry to vary in 3D. I guess that It's important to define the geometric paramters as "Parameters" and not as "Variables". Maybe that's what I was doing wrong. Thank you for your help,
Fernando.
