# Calculation

Before you start the calculation, you can perform a Plausibility Check of input data.

The Calculate menu offers various options to start the structural analysis of the model. They are described in the Starting the Calculation chapter.

If the options for Cloud Calculations are activated, further menu items become available.

In the "Calculate" menu, you can also access the Static Analysis Settings.

## Member Divisions for Calculation

The distribution and the degree of refinement of the graphic results are based on the settings specified in the 'Member Divisions for Calculation' dialog box. You can open this dialog box using the Member Divisions for Calculation function in the 'Calculate' menu.

#### Number of Divisions for Result Diagrams

The value entered in this text box affects the graphical result distribution of the members: For example, if a division of 10 is set, RSTAB divides the length of the longest member within the model by 10. Based on this system-related division length, RSTAB determines the graphical result distributions on the division points for each member (see the image Bending Moments).

#### Number of Divisions for Special Types of Members

In contrast to the division option described above, a real division of the member is defined by internal intermediate nodes. This specification affects elastic foundation members with an unsymmetrical cross-section (contact pressures), tapered members (interpolation of section values), and members with plastic properties (yielding areas).

#### Number of Divisions for Determination of Max/Min Values

The value of this text box specifies the internal division by which the maximum and minimum internal forces of members are determined. Thus, this division (default setting: 10) represents the basis for the extreme values shown in the results tables and graphics.

#### Activating Member Divisions for Large Deformation Analysis

This option also makes it possible to divide beams by intermediate nodes for calculations according to the large deformation analysis, and thus to determine them with greater accuracy. The number of divisions for special member types is used.
