Thermal Solver

The thermalSubSolver class is used to handle the modeling of heat transfer in OFFBEAT.

The primary field in the thermal solver is the temperature, represented by <b>T</b> and expressed in <b>K</b>. The corresponding temperature field file must be present at the start of the simulation to set both the internal field and boundary conditions accordingly.

The thermal solver must be selected with the thermalSolver keyword in the main dictionary of OFFBEAT (i.e. the solverDict dictionary, located in the constant folder).

Classes

Currently OFFBEAT supports the following thermal solvers:

  • constant - deactivates the thermal solution (i.e. no equation is solved) and the temperature T file is defined in the starting time folder. The old name for this class fromLatestTime is now deprecated;
  • readTemperature - at each time-step the temperature field is read from a sub-folder in the constant/ folder;
  • solidConduction - solves the heat conduction equation with the possibility of adding a volumetric source Q;
