What is the effect of the "Use division for members with nodes lying on them" option in FE Mesh Settings?

Answer

The "Use division for members with nodes lying on them" option divides a member internally divided at the member locations where nodes are resting.
The structure in Figure 01 includes two members, Member S1 from Node 1 to Node 2, and Member S2 from Node 3 to Node 4.
If you select the "Use division for members with nodes lying on them" option, Member S1 will be divided internally at Node 4. Thus, Member S1 is connected to Member S2, which is also visible on the deformation (Figure 02).
If you deactivate the "Use division for members with nodes lying on them" option, Member S1 will not be divided at Node 4. Thus, Member S1 is not connected to Member S2. Figure 03 shows the deformation in this case.
The structure in Figure 04 includes Member S1 from Node 1 to Node 2. On the member, there is Node 3, to which a nodal load PZ = 50 kN is applied. The nodal load is only applied to Member S1 if selecting the "Use division for members with nodes lying on them" option (Figure 05). If this option is deactivated, Member S1 is not subjected to this nodal load (Figure 06).
