Chrono example: CaseFlexibleGate, why the friction coefficient does not affect anything
Hi, I was trying to running the example file: caseflexiblegate. I firstly run the code without any modification. Then the second trial I opened the file "Floating_Materials.xml" and changed the kfric to 1000 times larger. The "Floating_Materials.xml" defines the material properties that is called by the "CaseFlexibleGate_Def.xml".
My question is, when I compare the two simulations, why they are exactly the same? Shouldn't it be different since I have changed the friction coefficient? Does the "fric" means the friction between the fluid and the solid boundary?
