Most of the questions on this forum are of way higher level than those I need to ask, but I haven't found any other place, so here they come.
As my first (and only so far) achievement with SystemModeler, I was able to design a brick and have it subjected to gravity.
But when the simulation starts, it goes straight through the ground.
1) Why doesn't my brick simply lie on the ground ?
2) How do I apply a constant force on my brick in a chosen direction ? I found a relatively close example but it involves several models I don't understand and can't adapt to what I intend to do.
3) I saw several animations in which it was possible to change the value of a parameter (say, the brick's mass, the force applied,...) with a slider, but all had been designed exclusively with Mathematica. Is it available in SM also ? (and where ?)
Thank you for helping a free-lance amateur.
