SOLIDWORKS Simulation - Topology Optimization

[@stephensmith799]

I REALLY enjoyed this vid. Thanks. I noticed that you applied your own aesthetics to the topologically optimised bracket, enhancing its appearance very much. I think the relationship between topological optimisation and engineers' aesthetics is very interesting. The T-O.ed bracket looks a lot better after you applied your design judgement to it. Somehow I would trust it more than the more 'bone-like' solution which Solidworks generated to begin with. I guess everybody has implicit feelings for things, even we non-engineers...

[@AshkanMehrizi]

Thanks You solved my problem easily by your describtion❤

amazing! great job, best regards, BRASIL

Great video

Such a fantastic tool!

Excelente vídeo. Parabéns! Fron Brasil

Whenever I try to run the Topology Optimization study i get an error that says "Result Files are not available. You may have to re-run the study..." Any idea how to rectify this issue?

[@kingbrolathia9877]

Hi Gary, in my experience I was able to rectify this issue by changing the geometry of part to be slightly larger, and saw another user solve the same error by moving the file path. That being said I suggest adding more material to the part if possible or moving the file path on the properties section of the Solidworks study. Hope that helps you troubleshoot!

5:20 how did you go from the weird looking one to the smooth design. The first one doesn’t look clean enough for display

[@RoySmits24]

He most probably redid the model and used the outcome from the optimization as a reference. So he took a look at the outcome to see where ie a smaller thickness was possible.

[@miguelhidalgo94]

It can also be done with Polynurbs

[@CurrencyPrime]

Hi, I'd like to point out that this simulation is very flawed and I see this in many "tutorials" of this kind. I actually don't think that I saw a single video where such a showcase was properly done. The reason is that you miss-use cylindrical constraints while you need a contact or proper spring model. Have a look at the top left corner. Where do you think it would break? Now look where you vonmises stresses are higher, would you not expect the exact opposite?

[@NavinF]

How would I go about creating "a contact or proper spring model"?

[@CurrencyPrime]

You need to use a contact with a proper interface that only considers pushing forces. A frictionless contact should suffice for this. Solidworks offers the no pen contact for that but probably not in combination with topology optimization. For that, use ANSYS of Optistruct@@NavinF

[@bazz9920]

But the structure is intended to be held by the cylinders right

[@CurrencyPrime]

@@bazz9920 That depends on the practical application. If the bolts are welded onto the part or if the entire assembly is actually only one part, then yes, one could model it that way. But at that point, why not make it a single part? In this case the bolts are not welded though, the part can freely rotate around the bolts. But the used contact is fixing nodes all around the cylindrical shape and these nodes now sustain pushing and pulling loads, which is not correct for a bolt. A bolt can only sustain pushing loads. To give you an analogy: a rope. A rope can only sustain pulling forces. Once you push it, it collapses. Now would it be correct to create a rope with a stiff beam? Certainly not.

Excellent

Thanks a ton! Fabulous video!

Great Video. How you make the cantilever

[@goengineer]

Great question! The cantilever is a simple extruded sketch with another extruded cut for the two circles. The exact dimensions are not very important if you would like to make a simple model to follow along with the video.

[@ahmadrezamovahedianfar3518]

Thanks

[@JaderVlog]

How can I set maximum angles restriction for 3d printing without helpers?

[@goengineer]

Hello. We don’t have overhang constraints with topology optimization as of version 2021. Thank you.

[@PreetSingh-xq8hk]

which mouse are you using?

[@habibullahyasin982]

hi sir why i cannot open the topology on the new study

[@stephensmith799]

Can you confirm whether or not harmonic resonance be optimised?

[@goengineer]

Hi Stephen, You can give the Topology Optimization frequency boundaries to optimize around in addition to the non-harmonic loading. You can specify, for example, that the resulting model have a first resonant frequency no lower than 1000 Hz and this will act as an optimization boundary for the calculation.

[@stephensmith799]

Wow... that could be very helpful as I am trying to optimize a musical instrument. Thanks for your post@@goengineer

[@user-de5xq2wk3n]

Really nice video. I followed step by step, but i keep geting a "Static solver failed" after i hit the "run this study". Any idea?

[@goengineer]

Please reach out to your VAR's technical support team so they can look at your specific set up.

[@nassuh100]

Why the topology study is grayed out and I can’t click on it?

[@goengineer]

The SOLIDWORKS Simulation tool has 3 tiers. The topology optimization tool is available in the second tier called SOLIDWORKS Simulation Professional. You should ensure that you have access to this level of the software to have access to this capability.

[@spirisoull]

Thnks!

[@sahilsave4305]

Is there a way to carry out similar process without decreasing the thickness of the material. We generally laser cut the plates thus making it difficult to change thickness.

[@goengineer]

You can use a combination of thickness and manufacturing constraints in the setup to ensure the nominal thickness is maintained where the material is retained during the optimization process. Thank you.

[@salaheddinelaalmi402]

love the video thank you

[@goengineer]

You are so welcome!

[@pradhumnj369]

Please can you tell the dimensions of this cantilever beam.

[@goengineer]

Unfortunately this model was made more than 4 years ago and we do not have the exact model any more. However if you watch towards the end of the video (6:00 ish) when they are discussing the cut out they do give dimension on that triangle. From there we can estimate the rough size of the at around 150mm on the long side and about 100 on the short.

[@KyleDB150]

It seems very limited, no stress constraints, other objective functions? I've used the one in Abaqus and it lets you set virtually any combination of objectives and constraints you can come up with

[@thormanfield1305]

Including wear rate?

[@KyleDB150]

@@thormanfield1305 If it can be output from abaqus in an implicit FEA procedure, then I think so. It doesn't make sense to use gradient-based topology optimisation for an explicit procedure. I'm sure this one has extra features like that, but the point is that abaqus can be much more general, not just maximising stiffness

[@dharamkarsaiabhishek4561]

can u suggest me how a topology optimization is done to obtain compliant gripper

[@KyleDB150]

I suggest looking it up in literature, it's been done

[@FirozAlam-rp9kn]

Is the optimization tool not present in solidworks 2016 Im unable to find optimization in simulation module

[@goengineer]

Hi Firoz, Topology Optimization did not yet exist in SOLIDWORKS 2016. It is a new function to SOLIDWORKS 2018.

[@karanbhatti1080]

doing same thing in 2016 final result is generating crash report.

[@karanbhatti1080]

and system crash

[@goengineer]

Hi Karan, If you are getting a crash in SOLIDWORKS, for any reason, you should go through this crash diagnostic process (kb.goengineer.com/go/default.aspx?kbID=12970) and/or involve your local VAR to assist in diagnosing the crash.

[@JMPatel-nk8gr]

I want to learn simulation please guide me

[@goengineer]

Hi Agza, The best advice I could give to you is find your local SOLIDWORKS dealer and sign up for a Simulation course: www.solidworks.com/sw/purchase/varlocator.htm

[@sidphillips718]

whats happens from 5:14 to 5:22 ?? How i can do that ??

[@goengineer]

Between 5:14 and 5:22, we extracted the raw shape from the analysis using extrude and cut features from SOLIDWORKS using the raw shape as guidance. You can use the simulation overlay tool to help with this. Check out this video for more details : kzbin.info/www/bejne/d17XkpqDjKd_eNk

[@shekharchhawsaria7660]

What's wrong wit the video between 5:0 to5:10

[@imatmind]

please give dimension
