Wheel rim topology optimization

Hi all,

Have you ever tried to do this interesting tutorial in new Altair Inspire verson (2022.3 or later)? Can you share the result?

You can download the model file and watch tutorial video in this Ebook: Simulation - Driven Design With Altair Inspire.

Re: Altair Inspire® Challenge #2: Cycling Shoe Cleat Design

Hi,

So I run some tests to optimize the structure, but it was not so easy to take something away. From the start model, it already bends 1,6 mm and von mises goes over abs limit (105 MPa). There was no mention about changing the material, so I stuck with abs.

Here is my optimize result:

So this is my result:

I got max displacment 2,18 mm and max von mises 123 MPa. The weight is now 21 g

PS.

I can’t understand how other have manage get rid of some much material and even get better stiffness.

Re: hello, i wanna know about radioss, rigid wall

how have you configured the rigid wall?

when you create the rigid wall, you have to add the structure nodes to the contact group of the rigid wall in order to activate the barrier effect.

Re: Altair Inspire® Challenge #1: Bridge Concept Design

Hmm. Am I doing it right? I cant run it like that? Should I be able to run it like that or should I do something( and that is the challenge? )?

Now I did try it again. There was still some problem, because the object materials where "materila 4". Was it supposed to be like that?

Anyways, I changed the material to steel (S355) and it worked:

only 0.00028 mm displacment.

Thanks, Karli! It looks great. On our end, we were able to run with the default material, but it could obviously be adjusted at your discretion.

Hi Karli, you may need/want to modify the design space and run settings to come up with a unique design. I'm afraid I cannot give too much away without spoiling the contest as it is meant to be open-ended, but if you continue to have troubles please let us know. Can I ask, were you able to run an analysis on your model?

Re: Fixing the position and spawn of 1 large particle.

Just to add to what Jerrin said, which is definitely the way to do this for individual or maybe even 10s of particles, if you want to specify the exact positions of, say, 100+ particles, it would probably be easier to do it in a custom factory using an API plugin.

Food for thought.

Just to add to what Richard said, you can accomplish the same the goal using EDEMpy.

Re: Does anybody have a copy of rmx_text-ANY-9.4.0.jar to share?

Hi there,

there was a change from java 7 to a newer java from RM v9 to v10. So that might be the cause that you cant use newer versions.

Best,

Re: How to replace specific data points

Hi,

see this exmaple workflow below how this could be done. you could either use the "Map" (Numerical) or "Replace" (Nominal) Operator or the Data Editor.
