C******************************************************************* C** C** v e m c o n v e r t C** C** conversion between different mesh files formats C** C** by L. Grosz Karlsruhe, Sept. 1994 C** C******************************************************************* C** PROGRAM VEMEXM C** C**----------------------------------------------------------------- C** IMPLICIT NONE include 'bytes.h' C** C**----------------------------------------------------------------- C** C** some parameters which may be chanced: C** C** INPUT = name of the input file. The file extension C** specifies the data format: C** xxx.unv - the mesh is read from the ideas C** universal file xxx.unv, see idevem. C** xxx.neutral - the mesh is read from the PATRAN C** neutral file xxx.neutral, see C** patvem. C** all other cases - the mesh is read from the C** vecfem input file data, see C** vemu02. C** PRINT = name of the output file for the printing of the C** mesh. If the name has not the extension 'prt' the C** printing is skipped. C** IDEAS = name of the output file for the ideas universal C** file. If the name has not the extension 'unv' the C** printing is skipped. C** PATRAN = name of the output file for the PATRAN neutral C** file. If the name has not the extension 'neutral' C** the printing is skipped. C** ISVAS = name of the output files for the ISVAS input files. C** If the name has not the extension 'isv' the C** is skipped. Actual the files ISVAS//'.nodes' C** and ISVAS//'.elements' are written. C** STORAGE = total storage of process in Mbytes. C** COMP6 = handling of Dirichlet conditions, see vempat, C** patvem, vemide, idevem. C** NK = if you want to handle more than six components, you C** have to increase the number of components NK. C** INTEGER STORAGE,COMP6,NK CHARACTER*80 INPUT,PRINT,IDEAS,PATRAN,ISVAS PARAMETER (INPUT='mesh.unv', & PRINT='meshout.prt', & IDEAS='meshout.unv', & PATRAN='meshout.neutral', & ISVAS=' ', & STORAGE=10, & COMP6=0, & NK=6) C** C**----------------------------------------------------------------- C** C** special parameters explained in mesh(3): C** INTEGER MESH,GINFO,GINFO1,DINFO,DINFO1,LOUT,DIM PARAMETER (MESH =310, & DIM =3, & GINFO =30, & GINFO1=23+2*NK, & DINFO =GINFO+GINFO1*100, & DINFO1=17, & LOUT =6) C** C**----------------------------------------------------------------- C** C** the length of the array for the mesh are set: C** it will happen, that these lengths are to small for C** the given mesh. then you have to enter the correct lengths C** prescribed by the program into this declaration.
