You can use callback mechanisms to intercept this type of information and process it however you want. Look at demo_MBS_callbackSMC<https://github.com/projectchrono/chrono/blob/main/src/demos/mbs/demo_MBS_collisionSMC.cpp> and demo_MBS_callbackNSC<https://github.com/projectchrono/chrono/blob/main/src/demos/mbs/demo_MBS_callbackNSC.cpp>. Note that, depending on the contact formulation, some information may not be available.
--Radu From: [email protected] <[email protected]> On Behalf Of Yaqing Wang Sent: Thursday, April 11, 2024 3:21 PM To: ProjectChrono <[email protected]> Subject: [chrono] Contact between two objects Hi, I wonder if Chrono has a function to let me get the contact information of two specific objects. Like there are three objects A, B, and C, and they contact each other. I want to know the contact force, position, and normal direction to the contact surface of the collision between A and B only. If more, relative velocity and friction. I am using "ChBody->GetContactForce()" but it seems to give the sum of all contact forces.
