Re: [Yade-dev] How to change the macros
Hi, Anna, Is it not easier to add one more parameter to Wiremat? But you should first contact to original author of this file. Please, send diffs of files, not the whole ones. Because it is a little difficult to find, what you have changed. Thanks.

Re: [Yade-dev] How to change the macros
Hi, Anton,
I have to change the body of the class:
class WireMat: public FrictMat {
public:
virtual shared_ptrState newAssocState() const { return
shared_ptrState(new WireState); }
virtual bool stateTypeOk(State* s) const { return
(bool)dynamic_castWireState*(s); }
void postLoad(WireMat);
DECLARE_LOGGER;
YADE_CLASS_BASE_DOC_ATTRS_CTOR(WireMat,FrictMat,Material for use with
the Wire classes,
((Real,diameter,0.0027,, (Diameter of the single wire in [m] (the
diameter is used to compute the cross-section area of the wire).))
((vectorVector2r,strainStressValues1,,Attr::triggerPostLoad,Piecewise
linear definition of the stress-strain curve by set of points
(strain[-]0,stress[Pa]0) for one single wire. Tension only is considered
and the point (0,0) is not needed!))
/I've add a other vector in order to take
account of my two curves*/
((vectorVector2r,strainStressValues2,,Attr::triggerPostLoad,Piecewise
linear definition of the stress-strain curve by set of points
(strain[-]0,stress[Pa]0) for one double wire. Tension only is considered
and the point (0,0) is not needed!))
((bool,isDoubleTwist,false,,Type of the mesh. If true two particles
of the same material which body ids differ by one will be considered as
double-twisted interaction.))
/*((Real,lambdaEps,0.4,,Parameter between 0 and 1 to reduce the
failure strain of the double-twisted wire (as used by [Bertrand2008]_).
[-]))
((Real,lambdak,0.21,,Parameter between 0 and 1 to compute the
elastic stiffness of the double-twisted wire (as used by [Bertrand2008]_):
$k^D=2(\\lambda_k k_h + (1-\\lambda_k)k^S)$. [-]))*/
((vector,lambda,,Attr::triggerPostLoad,/*it contain the two lamdaEps
and lambdak in order to not have to modify the form of the fonction(don't
want to change the number of
parameters*/,lambda[0]=lambdaEps,lambda[1]=lambdak))
((Real,as,0,Attr::readonly,Cross-section area of a single wire used
for the computation of the limit normal contact forces. [m²]))
,
createIndex();
);
REGISTER_CLASS_INDEX(WireMat,FrictMat);
But it can't work with YADE_CLASS_BASE_DOC_ATTRS_CTOR() because of the
number of parameters so I've try to modify serialiazable.hpp in order to
have a new fuction with the number of parameters I need:
/** USER MACROS START HERE /

YADE_CLASS_BASE_DOC_ATTRS_INIT_CTOR_PY(klass,base,doc,attrs,,,)
#define YADE_CLASS_BASE_DOC_ATTRS_CTOR(klass,base,doc,attrs,ctor)
YADE_CLASS_BASE_DOC_ATTRS_INIT_CTOR_PY(klass,base,doc,attrs,,ctor,)
/*Adding a macro to have additional

#define
YADE_CLASS_BASE_DOC_ATTRS_attrs_CTOR(klass,base,doc,attrs,attrs,ctor)

YADE_CLASS_BASE_DOC_ATTRS_DEPREC_INIT_CTOR_PY(klass,base,doc,attrs,,inits,ctor,py)
Thanks.

Re: [Yade-dev] How to change the macros
Sorry, I still do not understand, why do you need to change Serializable.hpp If you need to add some more parameters to WireMat, you simply add it. Please, see attached diff. strainStressValues1 and strainStressValues2 are added and the code compiles just fine. But if you want to add it to the main trunk, please, contact Klaus Thoeni for those changes.

Re: [Yade-dev] How to change the macros
This alone should be enough: /I've add a other vector in order to take account of my two curves*/ ((vectorVector2r,strainStressValues2,,Attr::triggerPostLoad,Piecewise linear definition of the stress-strain curve by set of points (strain[-]0,stress[Pa]0) for one double wire. Tension only is considered and the point (0,0) is not needed!)) You surely don't need (and should not) modify the Serializable.hpp file. Your compilation problem is probably due to something else (and actually, there is no compile error shown in the log you sent). For showing diffs, type (for instance) bzr diff path/to/your/modified/file.cpp nameOfOutputFile.

All brackets that are not separated by commas are attrs, no matter how many attributes there are, for example, three attributes: (a)(b)(c) this is handled by preprocessor. no need to change macros. -- Janek Kozicki http://janek.kozicki.pl/ | ___ Mailing list: https://launchpad.net/~yade-dev Post to : yade-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~yade-dev More help : https://help.launchpad.net/ListHelp
Re: [Yade-dev] How to change the macros
Hoi Anna, as already pointed out by Bruno and Anton it makes no sense to change Serializable.hpp. If you want to add more parameters to to WireMat you have to define it in WirePM.hpp. However, in order to use this new parameters you would have to change the code in WirePM.cpp as well. Anyway, the actual code uses two different stress-strain-curves where the one for the double-twist is computed from the single wire curve by using the parameters lambda_eps and lambda_k (see Bertrand, some assumptions are made and the single wire curve is somehow scaled to get the one for the double twist). So if you know your stress-strain-curve for the double twist you just have to find out which parameters give you the expected behaviour.
