DefaultContactManager unrecognized in v24.12

[gayatriindukumar]

Hello,
I am using SOFA v24.12 on Windows. I am trying to simulate a simple scene where a solid cylinder interacts with a deformable surface. However, I am unable to use 'FrictionContactConstraint' as the response to my CollisionPipeline. Here are the relevant snippets of my scene.

    # Collision Components
    root.addObject('RequiredPlugin', name='Sofa.Component.Collision.Detection.Algorithm')
    root.addObject('RequiredPlugin', name='Sofa.Component.Collision.Detection.Intersection')
    root.addObject('RequiredPlugin',name='Sofa.Component.Collision.Geometry')
    root.addObject('RequiredPlugin', name='Sofa.Component.Collision.Response.Contact')

    root.addObject('CollisionPipeline')
    root.addObject("BruteForceBroadPhase")
    root.addObject("BVHNarrowPhase")
    root.addObject('LocalMinDistance', name='Proximity', alarmDistance=5, contactDistance=1, angleCone=0.1)
    root.addObject('DefaultContactManager', response='FrictionContactConstraint', responseParams='mu=0.99')

On running the scene, I get the following warning and the scene fails to load:

[WARNING] [CollisionPipeline(CollisionPipeline)] A ContactManager component is required to compute collision response and was not found in the current scene

The same scene file runs without any errors on SOFA v24.06

The desired result looks as follows:

Sim_test1.mp4

It has been renamed to CollisionResponse (#3891)

Thanks for the response. The documentation isn't very clear on the Collision Component. Where can I find a list of all possible collision responses and an overview of how they work?

To know the available response methods:

selectResponse.mp4

Unfortunately, there are no documentation to describe each of the methods. I'll create an issue for that. You can investigate in the code. All the responses are in https://github.com/sofa-framework/sofa/tree/master/Sofa/Component/Collision/Response/Contact/src/sofa/component/collision/response/contact. You can also ask specific questions.

Thank you, this is very helpful.
