Program Parameters

     usage: cgx [-a|-b|-c|-duns2d|-duns3d|-isaac2d|-isaac3d|-foam|-stl|-g] ->
            filename [ccxfile]
      [-v](default) read a result file in frd-format and optional a solver
          input file (ccx) in addition which provides the sets and loads
          used in the calculation.

      -a  automatic-build-mode, geometry file derived from a cad file is
          expected
      -b  build-mode, geometry file in fbd-format is expected
      -c  read an solver input file (ccx, Abaqus)
      -duns2d  read duns result files (2D)
      -duns3d  read duns result files (3D)
      -isaac2d  read isaac result files (2D)
      -isaac3d  read isaac result files (3D)
      -foam    read the OpenFOAM result directory structure
      -stl  read an stl file (triangles)

     special purpose options:
      -oldbias      convert pre-1.5 bias
      -mksets       make node-sets from *DLOAD-values (setname: "_<value>" )

If no option is provided then a result-file (frd) is assumed, see ``Result Format''.

A file containing commands or geometric informations is assumed if the option -b is specified. Such a file will be created if you use the vda2fbd or step2fbd interface or ``exit'' or ``save'' after you have created geometry. Option -a is the same as option -b but merging, defining of line-divisions and the calculation of the interiour of the surfaces is done automatically and the illuminated structure is presented after startup. With option -a and -b the program will start also if no file is specified.

An input deck for the solver can be read with option -c, see ``send''. Certain key-words are known and the affected nodes or elements are stored in sets. Default sets are +bou(dof) to store nodes which are restricted in the corresponding degree of freedom and the sets +dep(dof) and +ind(dof) to store dependent and independent nodes used in equations.
A special case are results of OpenFOAM. The results are organized in a directory structure consisting of a case containing time-directories in which the result-files are stored. The user must call cgx using the case-directory (cgx -foam case). The program will then search the time-directoies. The time directories must contain a time-file to be recognized. Or in other words each directory in this level containing a time-file is regarded as a result directory.

To convert from pre 1.5 versions start the program with the -oldbias option. This will modify the bias parameters of lines.
