};Description
DVisoline creates contour lines of a given level value in a 2D field. The contour lines can be colored by the level value. The selected component must be scalar.
Input
The input is a reference to a field with a 2D mesh and Node_Data. The mesh can be of any defined type (Mesh, Mesh_Struct, Mesh_Unif, Mesh_Rect). However, the mesh must be 2D (nspace = 2 in .
fields, cell_ndim = 2 in unstructured fields). No checking is done to ensure that the mesh is 2D. 3D meshes will not generate output. The Node_Data must have a single scalar component.
A float. Sets the isoline level. The data type is converted to the data type of the input field prior to use.
Output
The output is a new object that contains an unstructured Mesh of cell type Line that represents the contour lines. The value of the Node_Data is the level value.
For each "cell" of the 2D field, a straight line is created connecting locations on the cell's edges with an interpolated value equal to the level. The interpolation is linear.
