Hi guys,

Maybe I should have opened a bug for that, but it seems that STL import does
not handle the case where body state is customized. For instance, with
CohesiveFrictionalPM, where body state is customized to body CFpmState
(inheritance from body state BTW), when I launch a python script which
contains those lines:

facetMat =
O.materials.append(CFpmMat(type=0,young=1e9,frictionAngle=radians(30),poisson=0.4,density=2600))
O.bodies.append(ymport.stl('Yplane.stl',wire=False,color=(1,0.99,0.99),material=facetMat))

I get this error message:

O.step();
RuntimeError: Body #0: Body::material type CFpmMat doesn't correspond to
Body::state type State (should be CFpmState instead)

Looking into the corresponding xml shows that, indeed, body state is not
defined as body CFpmState, which produces the error. I have checked that the
error does not come from CFpm itself by launching the same script with the
same facet plane created from utils.facet:

facetMat =
O.materials.append(CFpmMat(type=0,young=1e9,frictionAngle=radians(30),poisson=0.4,density=2600))
O.bodies.append(utils.facet([[-1.,0.,0.5],[1.,0.,-1.],[1.,0.,1.]],wire=False,color=(1,0.99,0.99),material=facetMat))

and it works (body state is defined as the customized one in the xml).

Thanks for helping
