Example c3: Viewing a skull

The comfile run by this example is as follows:

Example_c3  Viewing the skull

#This example reads skull node and element files into
#CMISS, and then exports them in a suitable format for 
#CMGUI.  The exported files are then read into CMGUI and
#the skull is displayed.  Note that this problem requires
#a large parameter set for CMISS.  A suitable 
#parameters.inc file is given in the doc directory for
#this example.

#.exnode and .exelem files are also contained in this 
#directory, so that the skull may be viewed without  
#first exporting the elements. 

#export the finite elements
fem                                     #sets the environment to FEM
