FIELDThe FIELD Command option manipulates one or more specified fields in the Current Mesh ObjectFORMAT:*For all points in the specified point set, we compose the field value with the specified composition function. The composition functions allowed are currently

asinhandlog. So, for example, if 'i' is in the point set andasinhis the composition function, we have the assignment:field(i) = asinh(field(i)).*Thefield/mfedrawcommand causes a binary dump of the specified fields to two files in themfedrawinput format.mfedrawis a graphics package for visualizing moving piecewise linear functions of two variables, such as those originally encountered in Moving Finite Elements. The files are named 'root1.bin' and 'root2.bin', where 'root' is the root file name argument. Because the graphics data are a function of two variables, you must supply two orthonormal vectors (x1,y1,z1) and (x2,y2,z2) which specify the graphics coordinate axes. More precisely, given 3D coordinates (x,y,z), the 2D graphic coordinates will then be (x*x1+y*y1+z*z1 , x*x2+y*y2+z*z2). So, for example, the choice:/x1,y1,z1/x2,y2,z2/ = /1.,0.,0./0.,1.,0./causes the 'z' coordinate to be discarded while the 'x' and 'y' coordinates are unchanged.*The

field/scaleoption scales the field values of the specified points. scale option can take on the valuesnormalize,multiply, anddivide. Ifnormalizeis specified, we multiply all the field values byfactor/(fieldmax-fieldmin), where 'fieldmax' and 'fieldmin' are the maximum and minimum values taken over the point set. This has the effect of normalizing the field so that the new difference between the maximum and minimum values is equal tofactor. Ifmultiplyis specified, we multiply all the field values in the point set byfactor. Ifdivideis specified, we divide all the field values in the point set byfactor.*The

field/volavgoption, for all the members of the point set and for all specified fields, replaces the point field values with values that represent the average of the field(s) over the control volumes associated with the points. The averaging option specifies what kind of control volume is to be used; the choices arevoronoiandmedian. iterations is an integer that specifies a repeat count for how many times this procedure is to be performed on the field(s). The affect of this process is to broaden and smooth the features of the field(s), similar to the effect of a diffusion process. Thevoronoichoice, unlike themedian. choice, produces a diffusive effect independent of mesh connectivity. However, again unlike themedian. choice, itrequiresthat the mesh be Delaunay, or incorrect results will occur.field/compose/composition function/ifirst,ilast,istride/field list/field/mfedraw/root file name/x1,y1,z1/x2,y2,z2/field list/field/scale /scale option/factor/ifirst,ilast,istride/ field list /field/volavg/averaging option/iterations/ifirst,ilast,istride/filed list/EXAMPLES:
