In fact, the user manual is composed of a part which is independent of the choosen language (the syntax) and of parts specific for each language. For example, if you ask for " OPTION LANGU JAVANESE ", the INFORM operator will print only the syntax of the operator and error messages will be in french because they do not exist in javanese. The NBP option is used to merge simultaneously with RESTituer the results of several calculations done with the same mesh. In case of MODE FOUR option, the number of harmonics for the symmetrical modes will be considered positive, that of the anti- symmetrical modes will be considered negative. If you specify MODE FOUR NOHARM, you may create objects that you will be able to use in MODE FOUR whatever the harmonics may be. In case of MODE PLAN GENE option, give a point which will support the additionnal unknowns (translation and rotations of the main section) and will be used as a reference to the rotation of the main section. The current values for the options may be obtained through the VALE operator. The 'FTRA' option may only be used when the graphic output is of PS, PSC or MIF type. It allows not only to choose the name of the file containing the drawings but also to change it during a session. The creation of several graphic files during one session is thus possible. For the TRAC option, and depending on the data processing system, BENS creates files of LGI type, IBM's graphic system is called GDDM, GKS's is called GKS, PHIGS's is called PHIGS, X's interface is called X-WINDOW, PS creates files of monochrome Post Script type, MIF creates files in Framemaker format and PSC creates files of color Post Script type. For the NORM option, it is required that a LISTMOT containing the initial unknowns to be normalized be given as well as the LISTREEL providing the standardization factor. You may also ask for automatic standardization ('AUTO') but this may take some time. ex1: to change unit, from mm to meters, give 1000. ex2: for the fluids, you may give the following values : ROREF CREF and LCAR to 1, and normalize P by means of ROREF *CREF *CREF / LCAR and PI by means of ROREF*LCAR). The 'ANNU' keyword may be used to stop the unknows normalization. Remark 1) When the variables scaling is on, the program duplicates all the elementary stiffness matrices in order to apply the scaling factors to them. The conclusion is that the program needs much more memory to solve a linear system when the scaling option is ON. Remark 2) When both the primal and dual variables are normalized the stiffness matrix looses its symmetry. It means that still more memory and CPU time are needed to solve your problem in this case. Remark 3) When a non symmetric matrix is to be normalized, the user should specify both the primal and dual variables' normalization factors. The 'AUTO' option is considered as if only primal variables were normalized, hence it does not work in the non symmetric case. Remark 4) The normalization options should not be modified between two (or several) inversions of the same (in the sense of a Castem 2000 object) matrix.
