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

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)

This question does seem so simple?

Here are the condition statements

- dia A > dia B
- depth A + depth B < part thickness
- dia A < part width
- min(depth B) = 0.1

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

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.

Can you post your model or at least some screen shots please.

EDIT: How much should A + B be less then the overall height
