# Nonmem Advan1,2,3,4,11,12 to PoPy analytic compartment models

Table 47 shows how to convert each Nonmem inbuilt ADVAN analytic functions to PoPy equivalents.

See ADVAN 1,2,3,4,11,12 Example for info on Nonmem $SUBROUTINES section.

Note to use the analytic compartment models in PoPy you should always set ODE_SOLVER as follows:-

    ODE_SOLVER: {ANALYTIC:{}}

For more information on PoPy analytic functions see Analytic Compartment Functions.
