In the rule-based design approach, soil reaction is defined via mathematical functions and can be derived from previous numerical-based calibrations on other projects (Calibration mode in PLAXIS Monopile Designer), or they can be user-defined from standard publications or supplied by a consultant.
In the latter case, the mathematical function itself consists of certain fitting parameters as a function of depth. This information should be specified by the user in the imported file, which has a specific format used to define the parameterised soil reaction curves. The file also includes relevant data for the site-specific soil conditions and the design (calibration) space based on which the soil reaction curves were generated.
The file format for importing user-defined functions is *.dvf (a plain text file with the .dvf extension). Conventional p-y curves, codified in industry standards such as API RP 2A-WSD, can also be considered as a form of a rule-based model. These can also be used in PLAXIS Monopile Designer, importing a different file format (i.e., .spy for sand and .cpy for clay) for input.
For detailed instructions, refer to the article Rule-based depth variation functions.
