Hi,
How I can impose displacement and velocity of a node in a mesh to a node of another mesh?

Hi Zahra,
You can use the AttachConstraint, see the associated example in examples/Components/constraint/AttachConstraint.scn.

Hi Hugo,
Thank you for your reply. I can attach the position using attach constraint, but what about the velocity?

Hi Zahra,
Did you try the LinearVelocityConstraint component ?

Dear Hugo,
I am trying to impose displacement and velocity of a node in a mesh to a node of another mesh using python. It is my first attempt to use python, however, but I have no idea what steps I should accomplish. I would appreciate any hint to do this.

Zahra
Hi Zahra,
Imposing both displacement and velocity sounds redundant to me since both state variable are linked through the integration scheme
e.g. Euler explicit: v(t) = ( x(t+dt)-x(t) ) / dt
I am sorry I am having hard time to understand the simulation you want to achieve.
What simulation do you actually intend to do ? what objects do you want to model ?
To discover all possible functions with Python, you can have a look at
or in applications/SofaPython at
I hope this helps.
Best wishes,
Hugo
