mfem.gridfunction.projectBdrCoefficient
Projects a constant value onto boundary DOFs for specified boundary attributes.
Syntax
mfem.gridfunction.projectBdrCoefficient(gf, value, bdrAttrs)
Description
Projects a constant value onto boundary DOFs for specified boundary attributes. This sets the DOF values on the specified boundaries to the given constant value. It is useful for applying Dirichlet boundary conditions where the boundary value is known. Only DOFs that lie on boundary elements with the specified attributes are modified. Interior DOFs remain unchanged.
Parameters
| Name | Description |
|---|---|
| gf | - GridFunction to modify |
| value | - The constant value to project on boundary |
| bdrAttrs | - Array of boundary attributes (1-based) to apply the value to |
Returns
void
