Ok. In fact, (Jerome) we see in the NewtonIntegrator something like _scene->forces.getMove(id)_, hence also move() is possible to use if we want to force a displacement. Anyway an engine is better since it is run every time step as Vaclav suggests. > > I am attaching script that I use(d) for plotting 1-1 graphs, take it as > inspiration, it is rather hairy.

It uses the JumpChangeSe3 engine. > Thanks a lot Vaclav. In fact, I was thinking to add a good general script to be used to test a contact law. I will since I am playing with tension/compression forces, loading/unloading... Just a matter of time. BTW, why sometimes I do not see consistence in assigned names of py/c++ functions? Like getMove() and move()... It would be simpler to maintain the same... cheers, Chiara > > It runs 3 scenarios, the one you might need is distProx perhaps. > > HTH, Vaclav > > _______________________________________________ > Mailing list: > https://launchpad.net/~yade-users<https://launchpad.net/%7Eyade-users> > Post to : [email protected] > Unsubscribe : > https://launchpad.net/~yade-users<https://launchpad.net/%7Eyade-users> > More help : https://help.launchpad.net/ListHelp > >
