Directory Contents and Description:
  
Driver.d/  Contains the main driver routines for linear statics, linear
                dynamics, and eigenvalue problems. The drivers are  
                StaticProbType.{h,C}, DynamProbType.{h,C}, and  
                EigenProbType.{h,C}.
  
Element.d/  Contains element class definitions and all routines necessary
                to implement the following elements: truss, Euler beam,  
                Timoshenko beam, Quadrilateral plane stress, translational spring,
                rotational spring, ANS shell, composite shell, and solid brick.
    The file AddElem.C contains the routine that builds the element
    set from the input file. Element.{h,C} contains the abstract
    definition of an element along with the structural properties
    class, Node class, CoordSet class, and Elemset class.
  
Examples.d/  Contains an example problem for linear statics, linear
    dynamics, and eigenvalue problems. These input files give
    an idea of how input is read into the FEM code. A more detailed
    manual is availible by contacting Charbel Farhat.
  
Main.d/    Contains a file for declaring compiler options.
  
Math.d/    Contains classes pertaining to vectors, matrices, and sparse
    matrices. The class SparseMatrix is a super class for the  
    following specific sparse matrix types: SGISparseMatrix,
    DBSparseMatrix, NBSparseMatrix and SkyMatrix.
  
Parser.d/  Contains the code necessary to read input data files.  
    lex/yacc is used to generate a parser based on keywords.
  
Problems.d/  Contains problem description classes for linear statics, linear
    dynamics, and eigenvalue problems. These classes are used in
    conjunction with the driver routines for the respective problem
    types.
  
Solvers.d/  Contains solver definition classes along with the abstract class
    definition of a solver which is contained in Solver.{h,C}.
  
Timers.d/  Contains routines that are used to time the programs and monitor  
    memory usage.
  
Utis.d/    Contains auxilary classes and/or functions that are used  
    throughout the FEM code. For example, Connectivity.{h,C} is
    a general class that is used to store adjacency information
    ( i.e. node to node adjacency, or subdomain to element, ...)
  
main.C    initial entry point for the FEM code
  
basedir    used to locate include files, should be set to the users
    directory where the FEM code is located.
    
------------------------------------------------------------------------------
  
How to compile the FEM code:
  
  1. set appropriate architecture compiler flags (in Makefile)
  2. type make all
  3. executable is called miniFEM
  
Note: linking with BLAS is required
  
BLAS ROUTINES
  
DGEMM
DGEMV
  
LINPACK ROUTINES
DSVDC
  
where DSVDC uses the following functions and subprograms.  
      External DROT BLAS DAXPY,DDOT,DSCAL,DSWAP,DNRM2,DROTG  
      Fortran DABS,DMAX1,MAX0,MIN0,MOD,DSQRT
  
------------------------------------------------------------------------------
  
How to execute the FEM code:
  
  miniFEM <input file>
  
  where <input file> is an appropriate input file like the examples
  found in Examples.d/

thanks a lot

能解释一下么？？
什么有限元？用的是什么单元的？三角or四边？是否等参元？

heavenhell

谢谢了。
