Boundary mesh type🔗

General conditions are specified using the patch type entry in the $FOAM_CASE/constant/polyMesh/boundary file:

<patchName>
{
    type            patch;
    ...
}

Base types🔗

Boundaries reduce to one of the following types:

• Dirichlet: fixed value
• Neumann: fixed gradient
• Mixed: linear combination of Dirichlet and Neumann

Options🔗

Available general conditions include

• Coded fixed value
• Fixed gradient
• Fixed value
• Mixed
• Uniform fixed value
• Zero gradient
• electrostaticDeposition
• fixedInternalValue
• fixedNormalSlip
• fixedProfile
