nejib hadda,

In the 0.20 version, some codes were found from elasticcohesivelaw.cpp about applying a force on a ball/wall.

			ncb->bex.addForce (id1,-f);
			ncb->bex.addForce (id2,+f);
			ncb->bex.addTorque(id1,-c1x.Cross(f));
			ncb->bex.addTorque(id2, c2x.Cross(f));
while in the old version:
			static_cast<Force*>   (ncb->physicalActions->find( id1 , actionForce  ->getClassIndex()).get())->force    -= f;
			static_cast<Force*>   (ncb->physicalActions->find( id2 , actionForce  ->getClassIndex()).get())->force    += f;

			static_cast<Momentum*>( ncb->physicalActions->find( id1 ,  actionMomentum->getClassIndex() ).get())->momentum -= c1x.Cross(f);
			static_cast<Momentum*>( ncb->physicalActions->find( id2 ,  actionMomentum->getClassIndex() ).get())->momentum += c2x.Cross(f);


I hope it useful.
