This is the information needed for the analysis and not related to the geometry.
Mesh units are the units in which are represented the coordinates of the geometry and mesh. Results units are the units used to represent the results of the analysis.
The three components of the gravity define a vector, which will be normalized by Rambshell, and represents the direction of the gravity if the self-weight is considered. In this case, as there is no load self-weight, the gravity components are not used.
Beam Res granularity means the number of subdivisions that will have every beam to represent the results. More subdivisions give more quality in the results visualization and more disk space. This option does not modify the precision of the result, only its visualization.
Output_beams_Maximums When there are more than one loadcase, it is possible to output a special loadcase containing the maximums for beams. Option Automatic, outputs it only if there are steel sections. Option Always, output it if there are more than one loadcase.
With the option Solver type, the solver of the equations system that is used internally is chosen. Options are:
· Solver tolerance: When the iteration process reaches this tolerance, the solver will stop.
· Solver tolerance minimum: If the solver arrives to its maximum iteration number, this tolerance will decide if results are accepted.
· Max. iterations: maximum number of iterations permitted to the solver.
Normally, the best option is to choose Automatic. Advanced users should choose Skyline solver if it does not take too much memory and sparse solver for big problems depending on the available RAM memory.
The rest of the information of this window is not used for beam analysis.
Analysis type: This option must be set to Beams and shells for all the problems that have beam elements.
