Hello Sir,
I am working on contact force modeling and has taken referance of models from examples but given examples run as it is. And if i copy and paste the same block from it in the new file then it shows error as follows :
"['untitled/Sphere to Plane Force4']: External Force and Torque 'untitled/Sphere to Plane Force4/External Force and Torque PlaB' has its follower port rigidly connected to the world frame; it has no effect. You can configure this diagnostic in the Simscape Multibody Configuration Parameters dialog. "
