• MOOSE is capable of running multiple applications together and transfer data between the various applications.

• This problem replaces the thermal conductivity calculated by the Material with a value computed by another application that runs a phase-based micro-structure simulation.

# Create Micro-structure Calculation

1. Represent the packed steel balls as a continuous phase variable between 0 and 1.
• 0 = water
• 1 = steel
2. Modify PackedColumn to compute porosity from phase variable.
3. Create an AuxKernel that corrodes the steel as a function of temperature.
4. Compute the "effective" thermal conductivity across the domain.

1. Modify PackedColumn to use a variable for thermal conductivity rather than computing it.
