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.
