Detailed Description

This boundary condition sets a user-defined shear stress constant and uniform across a given patch by using the expression:

\[ tau_0 = -\nu_{eff} \frac{dU}{dn} \]

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries
    type             fixedShearStress;
    tau              <vector>;

    // Inherited entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
type	Type name: fixedShearStress	word	yes	-
tau	Shear stress	vector	yes	-

The inherited entries are elaborated in:
