The Stationary, One-Way MF and Time Dependent, One-Way MF studies are available with the Moisture Flow interface, which requires the Heat Transfer Module.

The Stationary, One-Way MF() study is used for stationary moisture flow computations where the model is one-way in the sense that the moisture variations are so small that they do not affect the flow.

The study consists of two Stationary study steps, the first solving for the fluid velocity and pressure fields, and the second solving for the relative humidity field. If an additional physics interface is added, then it is automatically added to both study steps.

The Time Dependent, One-Way MF() study is used for time-dependent moisture flow computations where the model is one-way in the sense that the moisture variations are so small that they do not affect the flow.

The study consists of two Time Dependent study steps, the first solving for the fluid velocity and pressure fields, and the second solving for the relative humidity field. If an additional physics interface is added, then it is automatically added to both study steps.
