Q. What API command can be used to change this AutoPIPE's Static Analysis Set setting?


 

AutoPIPE Command Data API Command

Analysis >Static Analysis Set > Modify > Nonlinear checkbox:

This can be done by changing the number of maximum iterations for non linear analysis. When the checkbox is checked it means that a non zero value is present for this property. If set to '0' the checkbox will become unchecked. Please refer to the below screenshot:
This can be found in the Data API help page : Model > LoadSet

Execute the nonlinear analysis using the red square in the figure below, Analysis >
Static Analysis Set> Modify> "OK" for Nonlinear Analysis:

 Execution of analysis via Data API is not possible at this moment, Dec 2025, but may be performed using Batch Generator / DOS Prompt.

Check the Gaps/Friction/Soil checkbox that appears in the red square in the figure
below, Analysis > Static Analysis Set > Modify:

This checkbox is automatically checked if Non-Linear is checked, and unchecked if
the Non-Linear checkbox is unchecked.
Setting the max_nl_iterations property to a value greater than 0 will automatically check both the Non-Linear checkbox and the Gaps/Friction/Soil checkbox.

Note that if creating a new model, or new analysis set, if the number of max iterations for non linear analysis is set to greater than 0, it will also be required to define the load cases for linear and non-linear analysis:

  • add_static_case
  • add_nl_static_case

Also to set other properties for linear/non-linear analysis, for correct setup.
