plotmesh

plotmesh  Plots FE nodes and mesh.
   plotmesh(nod2xy,el2nod,showelem,shownode,showbcnodeonly,shiftxleft,shiftxright,shiftytop,figno,mrksz,zeroattop,shiftx,fs)
   where;
   NOD2XY=xz (nodal coordinates, nodnum X 2)(#NOD)x(XY) = (#NOD)x2
   EL2NOD=conn (connectivity matrix, element X node)(#EL)x(#NOD)
   figno = Figure number for FEM mesh plot, if not given figno = 100;
   fs = font size, if not given fs = 9
   fs = FONTSIZE = 0 supresses numbering.
   fs = FONTSIZE = 9 by default.
   Default font name is used
   mrksz = size of the node marker, default is 15
   zeroattop = 1, if nodal coordinates has the origin on the top surface,
   default is zeroattop = 1, zero at top
   shiftx = the space to be shift along x axis for placing node numbers,
   default is shiftx = 0.005
   shownode = 1;showelem = 1;showbcnodeonly = 1;shiftxleft = 2.2;shiftxright = 0.5;shiftytop = .6;
