Information

This partial function defines the common inputs to functions that calculate the borehole internal resistances.

Interface

Revisions

• July 18, 2018 by Massimo Cimmino:
  Implemented multipole method.
• February 14, 2014 by Michael Wetter:
  Added an assert statement to test for non-physical values.
• February 12, 2014, by Damien Picard:
  Remove the flow dependency of the resistances, as this function calculates the conduction resistances only.
• January 24, 2014, by Michael Wetter:
  Revised implementation.
• January 23, 2014, by Damien Picard:
  First implementation.
