  • PFEM2D discretize Rectangle $startNodeTag $X1 $Y1 $hx $hy $angle $Nx $Ny $Ndf <-fix $fixList -mass $massList -vel $velList -boundary $boundaryList>
    • Discretizes a rectangular area in to nodes for subsequent triangulation and PFEM analysis
    • startNodeTag -- tag of the first node that is created
    • X1 Y1 -- global X and Y coordinates of the lower left corner of the rectangle
    • hx hy -- division length in the local x and y directions of the rectangle
    • angle -- angle of rotation between the local x axis of the rectangle and the global X axis
    • Nx Ny -- number of divisions in the local x and y directions of the rectangle
    • Ndf -- number of degrees of freedom for each node that is created
    • fixList -- list of fixity values applied to all nodes that are created (1 = fixed, 0 = free, default = "0 0")
    • massList -- list of mass values applied to all nodes that are created (default = "0 0")
    • velList -- list of initial velocity applied to all nodes that are created (default = "0 0")
    • boundaryList -- list of codes for including boundary nodes on the sides of the rectangle (1 = include, 0 = omit, default = "1 1 1 1")
    • The return value from this command is the tag of the last node created


  • PFEM2D fluid $nodeList <-append>
    • Assigns nodes to be fluid nodes
    • nodeList -- list containing the start and end nodes for assignment
    • -append -- appends the nodes to the current set of fluid nodes (otherwise, overwrites the current set)


  • PFEM2D structure $nodeList <-append>
    • Assigns nodes to be structure nodes
    • nodeList -- list containing the start and end nodes for assignment
    • -append -- appends the nodes to the current set of structure nodes (otherwise, overwrites the current set)


More commands will be documented soon
