Previous: Compatibility with Previous Interface
The interface program works in conjunction with an LR.STRAND-specific command environment. This environment is activated via the command 'PROPERTY FE-PROG LR.STRAND' and is used to prompt the user for loading conditions and material and physical property definitions. Environment variable FG_PRE_INT (see section 1.4 ) can be used to make LR.STRAND the default environment for all models.
It is important to note that the analysis environment can not be changed when material properties, physical properties or loads have been defined in the FEMGEN model.
THE USE OF THE LR.STRAND SPECIFIC COMMAND ENVIRONMENT IS NOW MANDATORY
