Suction Cup

[Dong-Le-gnoD]

Hi folks,
I am working on simulation using a deformable suction cup to pick up a deformable object. At this moment, I've already had a basic setup, both the cup and object are using deformable properties from STLIB.

However, I was wondering that how do I attach the object to the suction cup after the collision. Could you suggest any idea for the operation?

I am thinking of 2 options:

1. Attach two object by the indices, but it follows almost the same as Using AttachConstraint to tie deformable and rigid objects together #2735 . I move the suction cup down with arrowkey, and press "m" to connect two objects together, but it does not look good and it will crash.
2. After collision, any pair of indices are attached to each other. But I am ensure how to do it?

Here are the code and meshes
deformable.zip

Thank you!

Hi @Dong-Le-gnoD

We will very soon release the SuctionCup plugin which was used to publish the related papers. Possibly in December.
Else attaching both objects won't really take into account the pressure within the cup

I hope this message finds you well. I’m writing to follow up on the SuctionCup plugin update shared earlier—thank you for letting the community know it will be released soon, potentially in December.
As I’m currently working on a project that relies heavily on this plugin, I’m eager to get a bit more clarity if possible: Could you provide any additional details about the specific release timeline for the SuctionCup plugin (e.g., a target week in December, or whether there might be a preview/beta version available beforehand)?
This information would help me better plan my project workflow and avoid delays. Thank you so much for your time and support—your work on the SOFA framework and its plugins is incredibly valuable to users like me!

Hi @kefusong @Dong-Le-gnoD
The SOFA staff now has access to the plugin. We will take care of it as soon as possible, we have it in our scope.
I do not believe we find time to handle it before Xmas but at the latest in January.

We will keep you posted here.

Looking forward to your wonderful plugin!

Hi @hugtalbot, hope you're good! How's the suction cup plugin going? Thanks for all your great work!
