These must be formattedaccording to the following FORTRAN read sequence(normally compatible with TOSCA code OUTPUTS):OPEN (UNIT = NL, FILE = FNAME, STATUS = ‘OLD’)DO 1 J = 1, JYDO 1 I = 1, IXIF (BINARY) THENREAD(NL) Y(J), Z(1), X(I), BY(I,J), BZ(I,J), BX(I,J)ELSEREAD(NL,100) Y(J), Z(1), X(I), BY(I,J), BZ(I,J), BX(I,J)100 FORMAT (1X, 6E11.4)ENDIF1 CONTINUEwhere ›éQí , *é(í are the longitudinal, horizontal coordinates in theat nodes é¢(í of the mesh, $Z(1)$ is the vertical elevation of the map, and ú , ú3 , úware the components of the field.For binary files, FNAME must begin with B ;’Binary’ will then automatically be set to ’.TRUE.’
