#Example_115 Defining a quadratic-linear FEM mesh
fem #sets the environment to FEM
fem define nodes;r;quad_lin;example #Read in 6 nodes for the quadratic-linear
# !element.
fem define window;c #bring up the xy window
fem draw axes #draw the axes
fem draw node #draw the nodes
fem define bases;p;quad_lin #Define one type of basis function
# !to be a Lagrange tensor product.
# !Define 2 Xi coordinates and define the
# !interpolant type in the Xi(1) direction to
# !be quadratic (type 2). All other options
# !are defaults. The file QUAD_LIN.IPBASE will
# !be created in your directory.
fem define elements;p #Define one element with element number 1
# !and 2 geometric coordinates (ie. 2D)
# !that uses basis function type 1 for both.
# !coordinates. The 6 global node numbers are
# !1 2 3 4 5 6 (in that order). The file
# !QUAD_LIN.IPELEM will be created in your
# !directory.
fem draw line #draw the element lines
fem draw element #draw the element number
fem list bases #lists the defined bases
fem list elements #lists the defined elements
