4.16 Member Divisions

General description

Member divisions are used to define points on members for which internal forces and deformations are later displayed in the results tables and numerical printout. A member division neither influences the determination of extreme values nor the graphical results diagram (RFEM internally uses a more refined partition). Member divisions are therefore not required in most cases.

Do not confuse member divisions with FE divisions for members. FE nodes on "free" lines (not belonging to a surface) with member properties are only generated if the lines have an FE mesh refinement (see Chapter 4.23).

Number of Points

You can enter a maximum number of 99 division points in the dialog box. An entry divides the member into the desired number of equidistant points.

Relative distance of point from the member start

When you create a new division in the dialog box, the distances of three intermediate points are preset. They represent the relative distances in the interval of 0 (member start) to 1 (member end).

It is also possible to define irregular divisions for the specified points, as you can enter the relative distances freely. Be sure to follow the correct order of intervals: x1 < x2 < x3 ...

Graphically, any x-location on the member can be specifically evaluated (see Chapter 9.5). Thus, in most cases, manually entering member divisions and tediously determining relative distances is unnecessary.
