Thank you for your suggestions. I had a look to the state class and it seems that there is everything I need. However, I am still unable to use the blockedDOF feature due to my lack of coding knowledge...
As it is just for some preliminary tests, I tried through python scripting when I created my scene. I saw that DOFs can be managed through the bodies.state['blockedDOFs'], which is great. However, it seems that, doing so, I can only manage 1 DOF as blockedDOFs is a bitmask which can be chosen between these values: 0 for no restriction 1 for X 2 for Y 4 for Z 8 for RX 16 for RY 32 for RZ and I would like to avoid all rotations (in the same way as the DOF_RXRYRZ is defined). Does someone have any advice?
