Description

The fixedNormalSlip is a generic boundary condition that sets the patch-normal component to the field to a user specified field. The tangential component is treated as slip.

Usage

The condition requires entries in both the boundary and field files.

Boundary file 

<patchName>
{
    type            patch;
    ...
}

Field file 

<patchName>
{
    // Mandatory entries
    type                    fixedNormalSlip;
    fixedValue              <Type>;

    // Optional entries
    writeValue              <bool>;

    // Inherited entries
    ...
}

where:

Property Description Type Required Default
