Status in Yet Another Dynamic Engine: New
Bug description:
ubuntu karmic
yade version 1886
I get this error message when I try to import spheres from an ascci file,:
TypeError: No registered converter was able to produce a C++ rvalue of type boost::shared_ptr<Body> from this Python object of type int
and the simulation does not run, even if I can view the assembly when I ask for a new 3D view.
here is my script, and attached the ascii file
