If nonlinear material is used, the number of integration points can be adjusted. For example, when calculating steel fiber concretes, it may be necessary to increase the number. You can adjust the thickness properties in the 'Layers' tab.
There are 3 to 99 integration points possible over the height. You can set the number separately for each shift.
Furthermore, various integration methods are available for nonlinear materials in the 'Basis' tab. To do this, check the Specify integration method check box.
- Gauss-Lobatto quadrature
- Simpson's Rule
- Trapezoidal Rule
The three methods are described in chapter Integration methods .
