    Basic Examples  (2)

    This message is generated when mesh elements that are not valid are specified:

    Wolfram Language code: Needs["NDSolve`FEM`"]
    Wolfram Language code: ToElementMesh["Coordinates" -> {{0, 0}, {1, 0}, {1, 1}, {0, 1}}, "MeshElements" -> {QuadElements[{{1, 2, 3, 4}}]}]

    To fix this, a valid mesh element needs to be specified:

    Wolfram Language code: ToElementMesh["Coordinates" -> {{0, 0}, {1, 0}, {1, 1}, {0, 1}}, "MeshElements" -> {QuadElement[{{1, 2, 3, 4}}]}]

    This message is generated when mesh elements that are not valid are specified:

    Wolfram Language code: ToBoundaryMesh["Coordinates" -> {{0, 0}, {1, 0}, {1, 1}, {0, 1}}, "BoundaryElements" -> {Line[{{1, 2}, {2, 3}, {3, 4}, {4, 1}}]}]

    To fix this, a valid mesh element needs to be specified:

    Wolfram Language code: ToBoundaryMesh["Coordinates" -> {{0, 0}, {1, 0}, {1, 1}, {0, 1}}, "BoundaryElements" -> {LineElement[{{1, 2}, {2, 3}, {3, 4}, {4, 1}}]}]
