    Status: Answered => Open

behzad is still having a problem:

Alright. I have already created a new class of material, CohBurgersMat. I have shared it above. So, I create a new Iphys now.

But Iphys as I see it doesn't take any parameter from the material.
Anyway, I modified CohFrictPhys and named it to CohBurPhys.

Does it look fine?

=====================
#pragma once

#include<yade/pkg/common/NormShearPhys.hpp>
#include<yade/pkg/dem/FrictPhys.hpp>

class CohBurPhys : public FrictPhys
{
	public :
		virtual ~CohBurPhys();
		void SetBreakingState();

	YADE_CLASS_BASE_DOC_ATTRS_CTOR(CohBurPhys,FrictPhys,"",
		((bool,cohesionDisablesFriction,false))
		((bool,cohesionBroken,true))
		((bool,fragile,true,,"do cohesion disapear when contact strength is exceeded?"))
		((Real,normalAdhesion,0,,"tensile strength"))
		((Real,shearAdhesion,0))
		((Real,unp,0,,"plastic normal displacement, only used for tensile behaviour and if :yref:`CohFrictPhys::fragile` =false."))
		((Real,unpMax,0,,"maximum value of plastic normal displacement, after that the interaction breaks even if :yref:`CohFrictPhys::fragile` =false. The default value (0) means no maximum."))
		((bool,momentRotationLaw,false,,"use bending/twisting moment at contacts"))
		((bool,initCohesion,false,,"Initialize the cohesive behaviour with current state as equilibrium state"))
		((Real,creep_viscosity,-1,,"creep viscosity [Pa.s/m]."))
		// internal attributes
		,
		createIndex();
	);
/// Indexable
	REGISTER_CLASS_INDEX(CohBurPhys,FrictPhys);

};

REGISTER_SERIALIZABLE(CohBurPhys);
=====================


I'm not sure if the following lines are correct:


#include<yade/pkg/common/NormShearPhys.hpp>
#include<yade/pkg/dem/FrictPhys.hpp>

class CohBurPhys : public FrictPhys


Thanks
