The default units system for Rambshell and ramsolid is the International System (IS). They are:
These units can be changed in several parts of the program. Every window that asks for data for constraints, load or properties has a field to choose the units for that window. The chosen units are only applicable in the data attached to it in the same window.
The units in which are expressed the coordinates of the geometrical model are chosen in the Problem data window:
Data -> Problem data -> Units -> Mesh units
The units in which are expressed the results of the analysis can be chosen in:
Data -> Problem data -> Units -> Results units
Other predefined units that can be chosen are:
Results units can be expressed as:
Displacements are in m
Strengths are in N/m or N·m/m
Stresses are in Pa= N/m2
Displacements are in mm
Strengths are in N/mm or N·mm/mm
Stresses are in N/mm2
Displacements are in cm
Strengths are in Kp/cm or Kp·cm/cm
Stresses are in Kp/cm2
Displacements are in m
Strengths are in kN/m or kN·m/m (kN=103 N)
Stresses are in Mpa=106 Pa
Note that the units in this system does not form a compatible system.
