# Information

Model Hx1DInc represent the model of a counter-current plate heat exchanger where one of the two fluid is modeled as an incompressible fluid. It is based on the connection of different sub-components:

- A Flow1Dim component representing the flow of the fluid in one side of the exchanger
- A Flow1DimInc component representing the secondary fluid flow
- A MetalWall component representing the thermal energy accumulation in the metal wall
- A CountCurr component that enables the possibility of parallel or countercurrent flow

# Modelling options

In the Initialization tab the following options are availabe:

- steadystate_T_sf: if true, the derivative of temperature of the incompressible fluid is set to zero during Initialization
- steadystate_h_wf: if true, the derivative of enthalpy of the working fluid is set to zero during Initialization
- steadystate_T_wall: if true, the derivative of Temperature of the metal wall is set to zero during Initialization

# Numerical options

The numerical options available for the HxRec1DInc are the one implemented in Cell1Dim.
