I am trying to do optimization of a simple part. The part has two cut outs, one inside another. The depth of 1st is 'A', the depth of 2nd is 'B' I want to set the 'A'+'B' < overall height of the part. How I can set that? Thanks
Can you post your model or at least some screen shots please.
EDIT: How much should A + B be less then the overall height
Thanks for the reply. Assume that I want to minimize the weight of the following part. 'A' is a larger diameter cut. 'B' will be inside 'A'. The B min is 0.1". "A" + "B" cannot be larger than the depth which is 1" . How to set the relation in the optimization?
How much weight minimization are you looking for?
What are the diameters for depth A & B?
What is the minimum thickness before B depth breaks through part?
This question does seem so simple?
How much weight minimization are you looking for? (Look for the best value)
What are the diameters for depth A & B? (diameter A can be anything but larger than diameter B, and diameter A cannot be larger than the width of the rectangle part)
What is the minimum thickness before B depth breaks through part? (The B min is 0.1)
Here are the condition statements
Generally, optimization goals are set up for simulations, is that what you are doing? If not I think you answered your own question. Make diameter A infinitely close to the part width, diameter B infinitely close to diameter A, and depth of B to 0.1".
Unless I am missing something.
I have a more complicated problem over 10 variables with many relations between each variable. I put the simplest example here for discussion. I want to learn and get help of how to add relations between each variable for optimization. There are a few thermal condition that I did not put here, those are control the factor of safety
I understand now, I have only tried this with a static study however you may be able to use a Thermal study instead. I am not sure if it is what you are looking for or not but it will vary dimensions that you specify between values that you also specify. It will change these variables and see if it is closer to your goal (which can be set to minimize mass). You can also set the number of iterations to optimize further. It will then offer a few different design considerations.
Instead of trying to explain how to do it I will just leave you a link to an example. It is fairly straightforward once you mess with it for a while.
SOLIDWORKS - Setup a Structural Optimization Study - YouTube
EDIT: Here is an example of a thermal study
The static study can have thermal input
For the optimization youtube video, the problem is the variables are independent. It is not my case.
I would have to see your specific problem to diagnose it further. Any chance you could upload the model?
What tool are you currently using for your optimization? You should take a look at CORTIME.
CORTIME lets you set up multi-objective optimizations using a large range of Solidworks resources as variables and objectives. It looks like i might just be a perfect fit for what you are trying to do. In the multi-objective optimization you can use objectives as a soft constraint on your design. It will not enforce the constraint strictly but will penalize designs that break the constraints and thus make the optimization reject solution that break your constraints.
You can try it out for free, and see if it helps you. Feel free to ask, if you have any questions at all, or need help with getting started.
