These must be formattedaccording to the following FORTRAN sequence:OPEN (UNIT = NL, FILE = FNAME, STATUS = ‘OLD’ [,FORM=’UNFORMATTED’])IF (BINARY) THENREAD(NL) (Y(J), J=1, JY)ELSEREAD(NL,100) (Y(J), J=1, JY)ENDIF100 FORMAT(10 F8.2)DO 1 I=1,IXIF (BINARY) THENREAD(NL) X(I), (BMES(I,J), J=1, JY)ELSEREAD(NL,101) X(I), (BMES(I,J), J=1, JY)101 FORMAT(10 F8.2)ENDIF1 CONTINUEwhere ›éQí and Ié(í are the longitudinal and transverse coordinates and BMES is the field component at a node é(íof the mesh. For binary files, FNAME must begin with B .‘Binary’ will then automatically be set to ‘.TRUE.’
