Contact between Tool and Discrete Element

[Clément]

Hey Damien,
I'm really sorry to bother you again :)

I got a new issue, I can't compute force between discreteElement and Tools,
Either force are not applied at all on the tool, either it interacts with the whole set of particle without having them in contact.

Can you please help me again :)

Here is a part of the inp:

  <PreProcessing>
    <PlugIn Id="_NewFrame" Center="(0,0.5,0)"  Quat="(0,0,1)(90)" ID="F1" />
    <PlugIn Id="_NewTool" Type="Box" DimX="0.5" DimY="0.1" DimZ="0.1" ID="B1" FrameID="F1"/>
    <PlugIn Id="_SetDensity" Density="700."/>
    <PlugIn Id="_ReadDomain" FileName="CompactDomain.agdd"/>
    <PlugIn Id="_ComputeOptimalTimeStep" Ratio="0.14" />

Hello, first, you need to reference your Tool in a given set as :

 
<PlugIn Id="_NewTool" Type="Box" DimX="0.5" DimY="0.1" DimZ="0.1" ID="B1" FrameID="F1"  Set="B1_Set"/>

 
After that, you should replace your collision detection "Body/discreteElement" by this one  :

 
<PlugIn Id="_ManageCollision" Between="Body/Body" 
    	     BroadPhase="Raw"  Set1="B1_set" Set2="Global"
	     NarrowPhase="WithShape"
    	     CallBack="Standard" Stiffness="1e7" RestitutionCoeff="0.1" />

It should work !

Thanks a lot, that may be the last time I ask you a question
