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 inside ramsolid, and represents the direction of the gravity if the self-weight is considered. In this case, it points to the negative Z axe.
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.
Smooth per material: When mixing two materials very different, like steel and concrete, the stresses are not continuus between materials. Then, it is necessary to set this option in order to see the stresses jump in the two materials boundary.
