1. Data Group B: Output from STAMOD Description of result presentation from static analyses is given in the following. 1.1. Results from static fixed parameter analysis Displacement and force data from static fixed parameter analysis are established by the STAMOD module and stored on file IFNSTA. Specifying this output after a parameter variation run will produce the results of the last parameter variation step. 1.1.1.

System information If you want information about the connection between the local line, segment and element number given as input to INPMOD and the global FEM element/nodal numbers generated by STAMOD, give STATic SYSTem INFOrmation NoPlot A more detailed description is given on the STAMOD print file. 1.1.3.
