SETSIZE
setsize will set the mesh object attributes xmin,xmax,ymin,ymax,zmin,zmax from the xic,yic,zic values of all 'real' points (dudded and merged points will be ignored). It also sets epsilon, epsilona and epsilonv as follows: setsize is called internally by LaGriT commands that add nodes to the mesh;copypts, createpts, regpnts, recon,scale, translate
epsilonv=abs(xmax-xmin)*abs(ymax-ymin)*abs(zmax-zmin)*epsilonr*1000.
epsilona=((xmax-xmin)**2+(ymax-ymin)**2+(zmax-zmin)**2)*epsilonr*1000.
epsilonr is set at initialization time by:x2=one
do i=1,1000x2=x2/twoenddo
x1=one+x2
if(x1.le.one) go to 11
11 epsilonr=x2*2.
Many LaGriT algorithms use epsilon1;
for example, if a node falls on a interface or boundary surface.
It uses epsilonv
to determine if a node can be connected. Errors from setpts
and connect may result if inconsistant or wrong values of epsilons
are used.
