As Luning mentioned, there is currently no support for reading a model specified through a URDF file. Not because Chrono uses an absolute coordinate formulation, as that is irrelevant here. Having said that, I intend to add this capability in the near future.
As for your question regarding flexible body dynamics, FFRF is not one of the formulations implemented in Chrono. We support ANCF and co-rotational. --Radu From: [email protected] <[email protected]> On Behalf Of Luning Fang Sent: Thursday, 16 February 2023 01:21 To: ProjectChrono <[email protected]> Subject: [chrono] Re: URDF support Chrono does not support URDF format yet. Chrono uses absolute coordinates instead of relative one. However, Chrono has robot models that were built from link and joint data, see RoboSimian.cpp<https://github.com/projectchrono/chrono/blob/main/src/chrono_models/robot/robosimian/RoboSimian.cpp#L132> as an example.
