Very Slow Dynamic Simulation

Anonymous — Fri, 26 Mar 2021 04:05:49 GMT

Is there any way to make dynamic simulation faster? like converting assemblies to a shrinkwrap (if it really does make it faster)

I am only a student and I have laptop that is below minimum requirements.

I really need it to be faster. Thank You

I am using Inventor 2018

Is there a logical reason why you have not shown your Dynamic Simulation browser in the images?

Attach your assembly here.

I'm sorry I cant attach the whole assembly here, it has more than 3 files. But here is my Dynamic Simulation browser. Thank you for Answering.

I don't think there is problem on how I made the simulation. Correct me if I'm wrong.

Don't mind the intersecting parts, or does it have an effect?

and I hope there is a way I can make the simulation faster.

Right click on the project folder.

Select Send to Compressed (zipped) Folder.

Attach the single resulting *.zip file here.

From the top level assembly file...

File>Save As>Pack and Go (as zip)

and Attach the resulting *.zip file here.

All else is just guessing.

Thanks for the Process you've just said, Sorry I didn't know such simple thing.

Hi! This is a very interesting project. You made the pine apple so realistic. But, I guess Inventor Dynamic Simulation cannot handle such high fidelity data. Try removing the Stem, Leaf and delete the pine apple skill. If it does not work with a cylinder, it won't work with a pine apple.

Many thanks!

Thank you. Btw, whenever I add a new part and don't add any joint or constraint and I switched Dynamic Simulation it is Automatically Grounded. Don't know the reason and why is it like that? How to fix it?

I tried using half section view, the simulation is now faster. Now 44hrs of waiting completes 57% of a 15 seconds simulation. I'm still waiting for another ways. But if there's no one can add more ways. I'll accept the solution of Sir Johnsons. Thanks for your time.

Hi! I believe that is how DS works. Any newly added component is grounded by default. You need to free up Degree of Freedom in DS, as opposed to reducing DOF (constraint or joint) in assembly environment.

Many thanks!

Thank you for the answers.
