Hi guys, what does a negativ update rate in a .world file mean? i was told that the simulation then runs as far as possible in order to provide nearly realtime simulation.But i cant find a documentation or explanation in ros or ODE. Is that true? Where can i find a documentation about that?? <physics:ode> <steptime>0.001</steptime> <gravity>0 0 -9.8</gravity> <cfm>0.0000000001</cfm> <erp>0.2</erp> <quickstep>true</quickstep> <quickstepiters>10</quickstepiters> <quickstepw>1.3</quickstepw> <contactmaxcorrectingvel>100.0</contactmaxcorrectingvel> <contactsurfacelayer>0.001</contactsurfacelayer> <updaterate>-0.1</updaterate> </physics:ode>

Yes, this is the case. See for example these two tickets on problems with the framerate locking mechanism (that should be fixed now): 1,2 Update Rate settings are also documented on the (old) gazebo problem resolution guide.
