Defining Boundary Conditions

Set the boundary conditions for the Ceramic, Clip+ve, and Clip-ve regions.

To define the boundary conditions:
  1. Select the Regions > Ceramic > Boundaries > outerceramic > Physics Conditions > Thermal Specification node and set the Condition to Temperature.
  2. Select the Physics Values > Static Temperature node and set Value to 310 K.
Set the boundary conditions for the Clip+ve region to have a stepped electrical potential, read from a table of Iteration vs. Potential Levels. The table is supplied as a CSV file, potentialLevels.csv.
  1. Right-click the Tools > Tables node and select New Table > File Table.
  2. In the Open dialog, select potentialLevels.csv and click Open.
    potentialLevels is added to the object tree under the Tables node.
  3. Right-click the Tables > potentialLevels node and select Tabulate.
    The content of the file is displayed in the Tabular Data dialog as shown below.

  4. Click Close.
  5. Select the Regions > Clip+ve > Boundaries > terminal+ > Physics Conditions > Electric Potential Specification node and set the Method to Electric Potential.
  6. Expand the Physics Values node and set the following:
    Node Property Setting
    Electric Potential Method Table (iteration)
    Table (iteration) Table potentialLevels
    Table: Data PotentialLevel
    Interpolation Step
  7. Select the Regions > Clip-ve > Boundaries > terminal- > Physics Conditions > Electric Potential Specification node and set the Method to Electric Potential.
  8. Select the Physics Values > Electric Potential node and set Value to 0.02 V.
  9. Save the simulation.
