Error for C code in Moose

[caoductoan379]

Dear All for help

I modified the code as follows:

#include "PFFracBulkRateMaterial.h"
#include "Function.h"

registerMooseObject("PhaseFieldApp", PFFracBulkRateMaterial);

template<>
InputParameters validParams()
{
InputParameters params = validParams();
params.addClassDescription("Material properties used in phase-field fracture damage evolution kernel");
params.addParam("function", "Function describing energy release rate type parameter distribution");
params.addParam("gc", 1.0, "Energy release rate type parameter");

return params;
}

PFFracBulkRateMaterial::PFFracBulkRateMaterial(const InputParameters & parameters) :
Material(parameters),
_gc(getParam("gc")),
_gc_prop(declareProperty("gc_prop")),
_function_prop(isParamValid("function") ? &getFunction("function") : NULL);
{
}

void
PFFracBulkRateMaterial::initQpStatefulProperties()
{
_gc_prop[_qp] = _gc;
}

void
PFFracBulkRateMaterial::computeQpProperties()
{
_gc_prop[_qp] = _gc;
/**

• This function computes heterogeneous gc
• User should override this function if heterogenities needs consideration
  */
  getProp();
  }

void
PFFracBulkRateMaterial::getProp()
{
if (_function_prop != NULL)
_gc_prop[_qp] = _function_prop->value(_t, _q_point[_qp]);
}

#include "Material.h"
#include "Function.h"

/**

• Phase-field fracture
• This class obtains critical energy release rate (gc) value
• Used by PFFRacBulkRate
  */

class PFFracBulkRateMaterial;

template<>
InputParameters validParams();

class PFFracBulkRateMaterial : public Material
{
public:
PFFracBulkRateMaterial(const InputParameters & parameters);

protected:
virtual void initQpStatefulProperties();
virtual void computeQpProperties();
/**

• This function obtains the value of gc
• Must be overidden by the user for heterogeneous gc
  */
  virtual void getProp();

///Input parameter for homogeneous gc
Real _gc;

///Material property where the gc values are stored
MaterialProperty &_gc_prop;
///Function to specify varying gc
Function * _function_prop;

private:

};

I compiled my code in phase field model. I received the error as follows:

/projects/moose/modules/phase_field/src/materials/PFFracBulkRateMaterial.C: In constructor 'PFFracBulkRateMaterial::PFFracBulkRateMaterial(const InputParameters&)':

Could everyone help to correct this error ? i really appreciate it .

Kind regards,

addParam needs a type: ie.
params.addParam<FunctionName>("function", "Function describing energy release rate type parameter distribution");

Also no semicolon is needed after the constructor
_function_prop(isParamValid("function") ? &getFunction("function") : NULL)

[jessecarterMOOSE]

Same goes for your gc param. Perhaps params.addParam<Real>?

Also I think when you declare the property, that is going to need a type: declareProperty<Real>

Thanks Jessecarter. I will try it and i will let you know what happens.

Kind regards,
