initQpStatefulProperties problem

[styyokuda]

Hi,
I used a program like below a few years ago but it does now work with today's MOOSE.
I get the error message of
"The parameter 'initial_length' is being retrieved before being set."
Please help!
Sincerely, S. Thomas

For the C file:
template <>
InputParameters
validParams()
{
InputParameters params = validParams();
params.addParam("initial_length",0.1, "initial length");
return params;
}

InitialProb::InitialProb(const InputParameters & parameters)
: Material(parameters),
_initial_length(getParam("initial_length")),
_value(declareProperty("value")),
_length(declareProperty("length")),
_length_old(getMaterialPropertyOld("length_old"))
{
}

void
InitialProb::initQpStatefulProperties()
{
_length[_qp] = _initial_length;
}

void
InitialProb::computeQpProperties()
{
float constant1 = 2, constant2 = 5;
_length[_qp] = _length_old[_qp] + constant1;
_value[_qp] = _length[_qp] * constant2;
}

For h file:
template <>
InputParameters validParams();

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

protected:
virtual void initQpStatefulProperties() override;
virtual void computeQpProperties() override;

private:
Real _initial_length;
MaterialProperty & _value;
MaterialProperty & _length;
const MaterialProperty & _length_old;
};

Move validParams() inside the class like so

class InitialProb : public Material
{
public:
  static InputParameters validParams();

  // ...
};

In the source file change accordingly

InputParameters
InitialProb::validParams()
{
  InputParameters params = validParams();
  params.addParam("initial_length", 0.1, "initial length");
  return params;
}
