Defining set in ManageCollision

[George.B]

Hello guys,

I want to define contact. So, I am using the plug-in "ManageCollision". I just want to define the contact for some specific blocks. I define a set named "blocks" and add it to the input file as:
<PlugIn Id="_ManageCollision" Between="Body/Body" BroadPhase="AABBTree" NarrowPhase="WithShape" CallBack="Standard" Set="blocks" Stiffness="1e10" />

But, no contact happens.
What do you think the problem is?
Thanks for your help

Hello, I suppose that your Set "block" is empty

[George.B]

It is not empty. Because, in granoo-viewer, The defined set "blocks" shows the blocks correctly.

The set is defined as:

auto& blocks = * new DEM::ElementT<Shape::Polyhedron>::Set("blocks");
for (unsigned int i=0;i<10;i++)
{
auto& firstDE = globalSet(i);
blocks.AddItem(firstDE);
}

Hello, please remove Set="blocks" and see what happens

[George.B]

I remove Set="blocks" and it works. When I add Set="blocks", it does not work.

Sorry, there is no way, it means that your set is empty
