Dear Bruno,
I am sorry, I don't know how to work on bzr version. Could you help
me? Which version is bzr version? Thank you very much. Looking forward
to your reply.
Cheers, Liqing

Dear Liqing,
All examples scripts of triaxial simulations are working correctly
without a gravity engine. So, you must have another problem that
the gravity engine is only hiding.
In order to help users in such cases, we need working scripts
generally, not just parts of them.
The other problem here is you are developing your own contact law,
which makes it impossible to test your scripts currently. We can't
help in this situation.
If it is improving something, you could consider working on the
bzr version and integrate your law in the source code after some
review from us.

Dear Anton,
Thank you very much for your warm help. My engine file is
following. But I organized the new Ip2, and Law2 files which are
modified based on Luc's model. As for triax, that is
"ThreeDTriaxialEngine". Without GravityEngine, I can't run it. It
doesn't work. But, including GravityEngine, it can work. If I set
the three parameters in GravityEngine to be zero, it also can't
work. I wish that the information I post here is enough. Thank
you very much.
O.engines=[
ParallelEngine([
ForceResetter(),
BoundDispatcher([Bo1_Sphere_Aabb(),Bo1_Box_Aabb()]),
InsertionSortCollider(),]),

[Ig2_Sphere_Sphere_ScGeom(interactionDetectionFactor=1.25),Ig2_Box_Sphere_ScGeom()],
[Ip2_LpmMat_LpmMat_LpmPhys()],
[Law2_ScGeom_LpmPhys_LPlasPM()]
),
#GlobalStiffnessTimeStepper(),
triax,
# you can add TriaxialStateRecorder and such here…
#PyRunner(iterPeriod=1,command='lateral()',initRun=False),
GravityEngine(gravity=(0,0,-0.1)),
