# ResultInternalForce2DEdge¶

**Internal force on 2D edge**

Internal forces on edge of 2D member. The coordinate system of the results is the coordinate system of the member the results belong to.

## Notes¶

## Index

This attribute defines an order of the section on the edge, starting with 1 and increasing from the

startto theendof the edge. This property helps to specify if the internal force is on the “left” or on the right side of the section.See example on a beam below:

Hint

See index 6 and 7. One section, two values for normal (N) force.

Section with lower index (6) identifies value on the left (closer to the origin of X-axis of the beam).

Section with a higher index (7) identifies value on the right (further from the origin of X-axis of the beam).
