Aluminium forced in the generative design results all the time

No matter what I have chosen from the Study Materials the results allways try to force aluminium alloys in them! Sometimes even when I separately go and tick them off while the generation has already started and see that the program has again ticked the alu options on(!), see below.

Further, I do not get any more results when I move the 'weight' bar to heavier direction, nor do I get get any less when moving to the lighter direction...

Bloody frustrating to wait for ages and get none,zip, zero, ziltsch applicable results!

Hi,

A couple of comments here. Firstly all the values you've shared in the screenshot are filtering options in explore. They don't have any impact on the actual outcomes which are generated for you, they just change the visibility in the explore environment. For example changing the mass slider in the objective ranges will not create any more or less outcomes, it will just hide outcomes that have already been generated.

If you want an outcome with a higher weight, there are some tools in generative design to allow you to do this, but you will need to generate a new study in order to create new results. For example, if you clone your existing study and change the objective to maximize stiffness, you'll be able to set a mass target in addition to a safety factor.This will create a new set of results that will all aim to be this mass or higher.

Regarding always getting aluminum outcomes. Again if you don't want aluminum outcomes from generative design, you will need to not select aluminum as a material in your setup. One thing I would point out here is that AlSi10Mg is the default material in generative design and so is applied as a material choice automatically.

There are two ways to apply a material in generative design, either to all manufacturing methods or to one manufacturing method specifically. By default AlSi10Mg is applied to each specific manufacturing method. So if you don't want outcomes from this material you need to go through each manufacturing method and remove it (a bit annoying I know!).

I hope this helps. In your post you mentioned that "even when I separately go and tick them off while the generation has already started and see that the program has again ticked the alu options on". Could you share a bit more about what you mean here? In the image you shared I can see that the aluminum material has been ticked off so I'm not sure exactly what you mean when you say that generative design turns it back on? If you share some more details I'd be happy to help

Thanks for the thorough and quick answer! Appriciate it.

 

I have deleted all aluminium material options from the study materials, and have added Inconel and AISI 317 to the list but dis not get any results with those materials, only AlSi10Mg.

 

With the weight the confusion was caused because there was no change on the amount of visible options, it was always four no matter where I slided the bar. But yes, it is only for the visibility of the different solutions.

 

But I'll try again checking that all is in proper order!
