Degrees of freedom
Fixed elements (with DOF = 0) are highlighted in the diagram. An icon in the top right corner of the screen indicates state of the system:
Indicates the diagram is in the indeterminate state. Some elements can move. Static calculations cannot be executed. Add supports, welds, or elements to fix elements that are not highlighted.
Indicates the diagram is in the equilibrium state.
The diagram is optimized for static calculations. Calculation report will contain inputs, equations, and calculation results.Indicates overdeterminate (over-constrained) state. The scheme includes redundant elements or supports. Static calculation based on numeric methods can be executed. Calculation report will contain inputs and calculation results.
