精准四面体,精准求积四面体,精准四面体考察对于一个三维(3D)四面体内部的,
精准求积规则的多项式的精准度.最高度数,如x2yz5的总度数是8.
(TETRAHEDRON_EXACTNESS, Investigate the polynomial exactness of a quadrature
  rule for a tetrahedron by integrating all monomials
  of a given degree.The rule will be adjusted to the unit tetrahedron.)
用户输入: User input:
  W file = "_w.txt".
  X file = "_x.txt".
  R file = "_r.txt".
  Maximum total degree to check =        0
At line 351 of file main.f95 (unit = 1)
Fortran runtime error: Cannot open file '_x.txt': No such file or directory

*******************
程序运行如上.
*******************
已经有这些数据文档:
W file = "_w.txt".
  X file = "_x.txt".
  R file = "_r.txt".
*******************
程序中相关读入数据指令:
......
             call get_unit ( input_unit )
                open ( unit = input_unit, file = input_filename, &
#351          status = 'old', form = 'formatted', access = 'sequential' )
              got_one = .false.
         10    continue
........

求助盼复, 谢谢老师!

有输入: (文件名)
keast7_w.txt, (the weights)
keast7_x.txt, (the abscissas)
keast7_r.txt ( the region)
8  (最高次数)
  报错,无法识别???
另*.txt 为数据文档

收到,谢谢! 可否用另一种方式输入
keast7_w.txt, (the weights)
keast7_x.txt, (the abscissas)
keast7_r.txt ( the region)里的数据内容, 及适当修改一下本程序中的数据读入指令,并附上_*.txt中的内容(已经有数据)于本程序上??!
