plane example

An infinite plane. The plane can be used to cut-out part of the domain, where the mesh in the plane normal direction will be preserved. The plane can be specified according to:

• pointAndNormal Plane is defined by point and normal vector
• embeddedPoints Plane is defined by 3 points

• planeEquation Employs the algebraic plane equation:

  \[ ax + by + cz + d = 0 \]

Usage

Plane defined by point and a normal vector:

plane
{
    type            searchablePlane;
    planeType       pointAndNormal;

    pointAndNormalDict
    {
        basePoint       (1 1 1);
        normal          (0 1 0);
    }
}

Plane defined by 3 points on the plane:

plane
{
    type            searchablePlane;
    planeType       embeddedPoints;

    embeddedPointsDict
    {
        point1          (1 1 1);
        point2          (0 1 0);
        point3          (0 0 1)
    }
}

Plane defined by plane equation:

plane
{
    type            searchablePlane;
    planeType       planeEquation;

    planeEquationDict
    {
        a  0;
        b  0;
        c  1; // to create plane with normal towards +z direction ...
        d  2; // ... at coordinate: z = 2
    }
}
