Geometry Information
  Much geometry information is maintained in the geom common block which is defined in the include file geom_lg.h.

nsurf	is the number of surfaces
nregs	is the number of regions
nmregs	is the number of mregions
maxdef	is the number of tokens in the longest region definition
maxmdef	is the number of tokens in the longest mregion definition.
lastregdef	end of regdef array
lastmregdef	end of regmdef array
lastsparam	end of sparam array

Geometry information is contained in a set of memory managed arrays whose partition name is the geometry name.

Retrieve the geometry name by:
           call cmo_get_attinfo('geom_name, cmo_name, iout, rout, geom_name, ipout, itype,ierror)

Surface information includes:
 

csall	surface name
istype	surface type (e.g. 'plane', cylinder, .....)
ibtype	boundary type (e.g. 'reflect;, 'interface', ...)
sheetnm	sheetname (for sheet surface types only)
surfparam	data describing the surface, varies depending on surface type
offsparam	offset into surfparam for a given surface

Region/mregion information includes:

cregs (cmregs)	region (mregions) names
ndetregs(ndefmregs)	number of tokens in region(mregion) definition
regdef (mregdef)	region (mregion) definition
offregdef (offmregdef)	offset into regdef (mregdef) for a given region (mregion)
matregs	material number fo a material region

subroutine get_material_number(mregion_name,number,ierror)
         returns the material number associated with the material region called mregion_name.

Any of the memory managed geometry arrays can be accessed using mmfindbk, for example:
          character*32 pointer (ipcsall, csall)
          call mmfindbk('csall', geom_name,ipcsall,length,ierror)
          where geom_name has been retrieved from the mesh object using cmo_get_attinfo.
