** nfr.h - Definitions and prototypes of module to read a 
**         two-dimensional frame model from a neutral format file.
**
** Description:
** ---------------------------------------------------------------
**
** This module contains functions to read a two-dimensional frame
** model dada from a file and to store these data in the 
** adopted data structure.  
** This data structure is described in file "crs.c".
** The model  data is read from a stream file in the neutral file
** format adopted in Tecgraf and Civil Engineering Dept. of 
** PUC-Rio. Please, refer to specific documentation on this 
** format.
**

**
** entry pts:
** ---------------------------------------------------------------
**
** void *nfrCrsModel( FILE *fd )
**
**       fd           - model data file descriptor            (in)
**
** This function reads the total number of nodes and elements of
** the model from the given neutral file and initalizes the 
** model in database.  It returns a pointer to the created model.
**
** ---------------------------------------------------------------
**
** int   nfrCrsNodes( FILE *fd )
**
**       fd           - model data file descriptor            (in)
**
** This function reads nodal coordinates from the given neutral 
** file and stores these data in database.
** Currently, it is assumed that in the file all the nodes are 
** numbered consecutively from 1 to the total number of nodes and
** that the nodal coordinates are grouped in only one section in 
** the file.
** This function also reads node support conditions.
**

**
** int   nfrCrsMembers( FILE *fd )
**
**       fd           - model data file descriptor            (in)
**
** This function reads beam element data from the given neutral file 
** and stores these data in database.
** Currently, it is assumed that in the file all the elements are 
** numbered consecutively from 1 to the total number of elements.
** This fucntion also reads material parameters, cross-section 
** properties, and beam end-liberation conditions.
