is:open i have working moose environment on my system . and i downloaded zapdos moose based app how to link it with my moose environment

[ankit72242]

can you please guide me step by step how to link such app that are open source moose based

[ankit72242]

@GiudGiud can you please suggest

[GiudGiud]

all you need to build zapdos and use it is here
https://shannon-lab.github.io/zapdos/getting_started/installation.html

by your moose environment, do you mean another app you made?

this is error coming while im following the instructions you provided in link. i checked all such syntax the file is correct

this is code where errror is mentioned

hello

this is extremely deprecated syntax, to the point it was removed

template<>
InputParameters validParams<CurrentDensity>()
{
  InputParameters params = validParams<AuxKernel>();

  // Add a required parameter.  If this isn't provided in the input file MOOSE will error.
  //params.addRequiredParam<Real>("conductivity", "The conductivity (sigma) of the metal");

  // Declare the options for a MooseEnum.
  // These options will be presented to the user in Peacock
  // and if something other than these options is in the input file
  // an error will be printed
  MooseEnum component("x y z");

  // Use the MooseEnum to add a parameter called "component"
  params.addRequiredParam<MooseEnum>("component", component, "The desired component of current density.");

  // Add a "coupling paramater" to get a variable from the input file.
  params.addRequiredCoupledVar("electric_potential", "The potential field.");

  return params;
}

you will need to update both the source and header to have the validParams be the way they are now

@GiudGiud i want to link danphe app to moose framework. is it possible bcoz above error are related to danphe app

[GiudGiud]

once you have fixed danphe you can use these instructions to use zapdos objects with a danphe executable
https://mooseframework.inl.gov/source/actions/DynamicObjectRegistrationAction.html

[ankit72242]

No I'm unable to link danphe....
These above error belong to danphe linking errors

[ankit72242]

In GitHub danphe working code
They are not updated I guess
Is there problem with danphe ?

[GiudGiud]

the code you pasted is severely outdated, it wont compile with a recent moose
