Just finished a parametric modeling case study of Tokyo Olympic Gymnasium (1960) by Kenzo Tange.
Parametric modeling is to build "relationships" rather than "geometries". Once the relationships are successfully created without conflicting each other, you can use parameters to update the outcome. If relationship fails to create updated geometry, Digital Project displays those collapsed geometries in red. I'm scared of seeing red by now. It takes time to update this complex model, and after good three minutes of praying, I saw it fail so many times. Took me while to make it update for extreme parameter changes.
Another fooling around shot with koinobori. Somehow I'm intrigued to those carp streamers. It's only once a year event in Japan when people hang koinobori. want to see hundreds of them together floating in the sky.
Goal_ Structural optimization runs for the purpose of achieving a Goal. ANSYS takes CATIA parameters, goes over every single one of them, and negotiate between them to achieve a Goal. Even in the case where multiple results are available, ANSYS stops the optimization as soon as it arranges the first available set of parameters. The software doesn't consider what parameter to calculate first, unless user assigns priority to parameters.
Boundary_ User can set Boundary for each parameter for the purpose of not losing the original form, or of considering the available material size. If the prior parameter reaches the boundary, and yet the Goal is not satisfied, ANSYS starts negotiating secondary parameters. Therefore, there are some cases where ANSYS doesn't give any answer. In those cases, user needs to reconsider the Goal, or give Boundaries more flexibility.
Stochastic Analysis_ Field of mathematics dealing with a process involving a randomly determined sequence of observations each of which is considered as a sample of one element from a probability distribution. also deals with Numerical Analysis. ANSYS employs Stochastic Analysis to go over and negotiate between multiple parameters to achieve a Goal within each prioritized Boundary.
In my younger and more vulnerable years my father gave me some advice that I've been turning over in my mind ever since. 'Whenever you feel like criticizing anyone,' he told me, 'just remember that all the people in this world haven't had the advantages that you've had.'
SCI-ARC hosted a conversation lecture about Dragonfly on 6/13. Dragonflyに携わった Architect と Structure Engineer によるレクチャー。
Stephen (Engineer): We used RISA, and ANSYS for optimization of this cantilever. We didn't get rid of every inches in the end, but we did pretty good job.
Eric Owen Moss : If you were to optimize, you were not gonna build it, c'mon...
Tom (Architect): I designed this tip to be 36 inches higher... I can reach it now.
Matthew (Engineer): Well, everybody seems pretty comfortable hanging out underneath it.
Following the previous post regarding thesis, this is the Floral St. Bridge CATIA model. Lionel's tutorial had more variety in form. I changed parameters so that
-both ends of the bridge don't change in size or location. -square frames don't change in size or shape.
I want to use Floral St. Bridge as an example of CATIA usage in aesthetics. In this case, the bridge was constructed off site and just dropped in place. Structure is strong enough to support 23 frames over 34' span. Only variety allowed was the overall shape (rotation of frames within xz plane and curvature of spline that connects one entrance to the other).
