ConductoDict Section
ConductoDict computes the thermal or electrical properties of composite or porous media, given the thermal or electrical conductivity of each constituent of the material.
The computation of effective conductivity properties of a material with ConductoDict is done following these steps:
- Generate a 3D-material model of a structure with a GeoDict generator or use a 3D-material model obtained from importing µCT or FIB/SEM 3D-image data.
- Select ConductoDict from the menu bar (Predict → ConductoDict) and
- Choose the appropriate command (Compute Thermal Conductivity or Compute Electrical Conductivity),
- Set the solver options,
- Run the effective thermal or electrical conductivity properties computation,
- Analyze the results.
Material Structures for ConductoDict
A variety of materials can be used as input for ConductoDict computations.
The constituent materials can be isotropic, transverse isotropic or orthotropic. Including the matrix or pore material, GeoDict handles structures with up to 256 different constituents. Specific constant resistivity can be used for both Compute Thermal Conductivity and Compute Electrical Conductivity.
For more examples of structures, see the References, in particular Wiegmann and Zemitis, 2006, Zamel et al., 2010, and Pfrang, 2010.
ConductoDict Graphical User Interface
Start ConductoDict by selecting Predict → ConductoDict in the Menu bar. The ConductoDict section contains a pull-down menu to switch between the commands Compute Thermal Conductivity and Compute Electrical Conductivity.
The Options for the selected command from GeoDict can be modified through the Edit... buttons.
When clicking the Estimate Memory & Disk-Space button, the RAM needed for the computation is estimated based on the size of the structure and the parameters entered in the solver options. The estimated computational memory and disk space requirements are shown in a Memory & Disk-Space pop-up message.
After that, clicking the Run button in the ConductoDict section starts the computations. If recording a macro, the Record button becomes active and the Run button changes to Run & Record.
Click Cloud to run it in the GeoDict cloud. See the Cloud handbook of the GeoDict User Guide for details.
Click Job Queue to submit the computation to the job queue. See the Job Queue handbook of the GeoDict User Guide for details.
After clicking Run, the computations start but the solver process can be cancelled or stopped when clicking Cancel or Stop in the progress dialog box. The difference between them is that Stop writes a GDR result file and give the intermediate result while Cancel terminates the simulation without giving GDR. Depending on the solver’s internal processes and actual memory usage, cancelling or stopping the computation may not be instantaneous.
