modelPartialDistributedVolume
Base class for distributed 1-D volume models
Information
The following boundary flow and source terms are part of the energy balance and must be specified in an extending class:
- Hb_flows[nVs], enthalpy flow rate (e.g., moving solid through boundaries)
- Qb_flows[nVs], heat flow term (e.g., conductive heat flows across discritized boundaries)
- Qb_volumes[nVs], sources of energy that are calculated from volume element state (e.g., convection or internal heat generation)
The following Inputs need to be set in an extending class to complete the model:
- Vs[nVs], distributed volumes
