Hi Deepak, thanks for spotting problem. I have no answer right now but I'm
forwarding to yade-mpi for future reference since it is becoming a
collaborative effort.

Subject: about insertAtId function.
To: Bruno Chareyre <bruno.chareyre@xxxxxxxxxxxxxxx>


Hi,

I  noticed something about the insertAtId function  (BodyContainer.cpp,
line: 30), inserting a new body at an erased location does not seem to
work, although the function returns the ID, the interactions and the state
of the body is not updated, and querying this body in the O.bodies list
returns None.

This is what I had tried :

b = sphere([0,0,0], 0.05)

b1, b2 = sphere([0,0,0], 0.05), sphere([0.25,0,0], 0.05)

O.bodies.append(b1); O.bodies.append(b2)

O.bodies.erase(1)

O.bodies.insertAtId(b,1) -->  returs '1'

and then :

O.bodies[1].state.pos --> returns "'NoneType' object has no attribute
'state'

Do I have to call a function to set the body state and other things after
insertion?


this line to be added in yadeWrapper.cpp :

.def("insertAtId",
&pyBodyContainer::insertAtId,(py::arg("insertatid")),"Insert a body at the
id, (no body should exist in this id)")

thanks and regards,

deepak

Arbitrary sized vectors are the problem i think.
