Acceleration on Body

[fstopelli-2]

Hello,

Is it possible in Simulate investigate the behaviour of body fixed on slide carriage with acceleration force?

Thank you

example att.

When use "Gravity Force", it is necessary that the WCS is in centroid G of the mass;

if not, I need to create a new coordinate system with X = Xg, Y = Yg, Z = Zg, correct?

[skunks]

yes

If I would like to consider the own weight (z = - 9.806 [m/s2]) of the 3D body that is in Simulate, I need add a Ideal mass in the Centroid G?

[skunks]

gravitation works on all bodies

[fstopelli-2]

But, for every surface I can know the value of force on it?

[skunks]

example: force1

[fstopelli-2]

what is the purpose of these?

Thank you

What does it mean this?

Warning: Resultant measure Forza_10
may not be evaluated correctly because there are
multi-point constraints (MPCs) near the resultant measure.
MPCs may occur in models with mixed or
incompatible meshes, links, fasteners, or
user coordinate system (UCS) constraints.

So, also in your example the surfaces of measure and of the rigid link are the same...

my weightet link is correct:
