Bottle Volume Optimization Task
This example clarifies use of optimization for 3D models. The file for the example is located in the library
“Documentation samples \2D Design\Optimization\ Bottle.GRB”.
The example presents the solution to the bottle volume
problem. In this example, the variable “Volume” is
created, equal to the bottle capacity, that is, the volume of
its contents. The variable “H” defines the height of the
bottle, while “HW” – the level of the liquid in it.
The optimization task is to maintain the constant bottle
capacity (0.5 liter = 500000 mm 3 ) while varying the bottle
height and the level of the liquid in it. To achieve this
goal, we need to find the value of the variable “D” driving
the median diameter of the bottle (the widest portion
diameter).
The optimization task “Volume” was defined in the
command “PO: Optimize Model” as follows.
The target function equates the variable “Volume” to
500000 with the tolerance equal 1.
The modifiable variable is “D”, in the range from 70 to 90.
No additional conditions are imposed on the model
variables; therefore, no restrictions are defined. To
visualize the optimization process, the flags are turned on,
“Show current result” and “Recalculate 3D model”.
The dichotomy method is selected for the optimization
algorithm, with the maximum number of iterations equal
to 100.
The parameter “Run” is set to the option “User”, so that
the optimization is run only upon the user request.
