Generative Design entity hierarchy

[pavmed]

Hi All!

I'd like to discuss here the hierarchy of entities in GD model. 

It's three level now: Model - Study - Load Case

1. Model is everything you have before GD - solid geometry (probably edited inside GD).

2. Study contains things you need to put together in order to formulate your task to GD algorithms - preserves, obstacles, materials, manufaturing and objective, etc.

3. Load case - as I understand - is a part of Study, a particular case where one could iterate and test "what if" hypothesis.

Everything seems fine but the fact that outcome space is shared between loads. So if I iterate new "what if" either in the same load case or clone it - I loose all previous outcomes and in fact cannot compare new and old case.

Why would anyone want to use more that one load case in Study?

Any thoughts regarding this topic are highly appreciated.

Take, for example, a suspension component on a vehicle. That component is loaded differently depending on what the vehicle is doing. Stationary (static), heavy acceleration, heavy braking, and heavy cornering all generate different loads in different directions and are some of the load cases. The part must successfully carry each load case so they must be considered at the same time (same study). If all of those forces were in the same load case, we might cancel some forces or exaggerate others.

In order to make evolutionary changes you must clone a study (or model) and then make the changes to the clone. This leaves the original study intact for comparison.

Ah! 

That was my second question.

So I use load cases to describe loads that applied to the same detail in different moments and they all will be considered in GD solution?

Correct.

Thanks a lot!

That greatly enhances my understanding of GD Study composition.
