usage: cgx [-a|-b|-c|-duns2d|-duns3d|-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) -stl read an stl file (triangles) -g use element-group-numbers from the result fileIf no option is provided then a result-file is assumed, see ``Result Format''. The program must be started with the option -g if the so called group numbers of the element-definitions are used in the result file. Otherwise the program will overwrite the group-numbers during startup, see ``group''. The CalculiX sover does not support this feature.
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.
