In the graphical representation of the line support forces I can see that the spacing between the arrows is very small. How can I modify it?
The spacing between the arrows depends on the FE mesh.
It is not possible to modify it by changing the display properties.
After the calculation a result value is found in each FE node, which results in the fact that any FE node includes also a value of the line support, and so a support arrow is displayed.
You can change the interval distance between the arrows by means of the target length of the finite elements. You can make the changes by selecting "FE Mesh Settings" on the "Calculate" menu.
