Usually, be consistent with tolerance between your parent bodies and weld should be fine. Welds are pretty accurate when joints modelled correctly. Convergence could be a topic in itself, which I will may be cover is another video.

It will apply acceleration about centre of gravity of the entire model, based on material density and geometry.

What error are you getting?

What kind of projects? If it’s hobby, I could help. If it’s official - I cannot.

In this case you need to perform a bolted joint analysis. Perform the FEA using idealised rigid link and extract forces from all three axes. Input those values in an online bolted joint calculator to see if its sufficient.

Pls check if you have rigid links between spring centre and hole’s outer edge. If u still get the error, run a modal analysis with rigid mode search turned on. It will tell you where your model is detached from the equation.

You need to choose hyper elastic material and perform non linear static analysis.

Thanks for additional information.

You can try mapped mesh option in “AutoGEM” controls.

You’re most welcome !

We fix mounting locations because those are gonna stay immovable relative to the rest of your body. Like nails in a door hinge. For complicated assemblies, we rigidly link bolted joints and fix ground locations (where it is connected to immovable structure or grounded to Earth simply)

I cannot help that situation, sorry.

I have got the solution

I don’t understand your comment

Minimum threshold value that your solver will count for showing your resultant natural frequency.

3D mouse

Hey there, I use 3D connexion’s space mouse.

If you are looking for professional use, go for Quadro with minimum 4GB video ram. For hobbyists, it would work as low as Gtx 710

Yes

Thanks, will let you know if I need support.

Thank you, I will

I don’t understand your question.

@@nothingbutengineering sorry, in which company are u working?

Unfortunately, there is no shortcut to do that. One has to shorten the length of welds in the weld definition itself. Another method is to use weld as a part by creating sweep features.

Good question. Most thin solid (sheet/plates) problems are linear problems and avoiding contacts will make sure most of load is going through the weld. While using contacts, friction may absorb some of the deformation or force. Also, using contacts forces you into non linear problems, which is not good for evaluating fatigue loads. But when you are interested in yielding and plastic deformation, its sensible to use contacts.

@@nothingbutengineering What if you use No Friction - Contact interface? In that case the Contact interface will not absorb any deformation of the face. It's a very good question and I would be happy to get a more in-depth explanation. Thank you in advance.

@@Druze_Tito Contacts are primarily used in non linear problems and for impact loads. For fatigue and eigen value problems, they are not preferred. And, Creo is not very good at handling contact non linearity.

@@nothingbutengineering I understand. But wouldn't the results be more 'accurate' to say per-se?

@@Druze_Tito Yes, they would be close to real life if we can have that option in solvers. I am not an FEA expert so I am not entirely sure of whether other solvers apart from simulate have that kind of fidelity while solving. Need to check. Anyways, thansk for bringing this up! Intriguing one.

Thank you, I will

Depends on your end goal. I use this feature to drive panel size in an elevator cabin for different values of height and width inputs given by field engineers. You won’t be able to visualise the aesthetics when you use simplified rep and reps don’t affect your bill of material I guess as it just hides features instead of suppressing it.

@@nothingbutengineering simp rep is not hiding parts from a assembly. It suppressed parts and as you know Creo is bi-directional associativity so it will affect your bill of material too.

The point is, pro program lets you automate the manual efforts needed to create reps. You need to manually pick each and every part while creating a rep. Image you have 100 different configurations and it’s really painful to do reps and suppress/Un suppress. It gets even more painful when your piece parts need feature suppressing based on driving parameter. I don’t think we can parametrically control which reps to pick from a sub assembly at top level based on input given at top level.

Hey Azarudin ! Thanks for taking time to comment. Your feedback is well received and the upcoming videos will surely fulfil your requests!

@@nothingbutengineering thank you, how to make the point size bigger it is not visible as what is in the vedio, i tried searching in option, entity display but couldnt find the right one.

@@azarudin1703 I am using Creo 8.0. If you are using any version before that, datum point would not look as big as show in the video. I tried searching for a config option to change its size but haven't found one yet. I will let u know if I find one. Thanks!

Thanks for your comment. I would like to bring to your attention that, my simulate videos are made with an intention to capture the engineering side more than explaining the software side of the subject. It is definitely possible for me to make a video explaining every button to click inside creo but, I don't find it meaningful without grasping the engineering application of the same. Hope it makes sense.

​@@nothingbutengineering got it....great 👍 cover same for mechanism part.
