| * '''PFEM2D discretize Rectangle $startNodeTag $X1 $Y1 $hx $hy $angle $Nx $Ny $Ndf <-fix $fixList -mass $massList -vel $velList -boundary $boundaryList>'''
| | [[FSI | < Back]] |
| ** 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

| ** Assigns nodes to be fluid nodes
| |
| ** '''nodeList''' -- list containing the start and end nodes for assignment
