src/PDE/CompFlow/Problem.h file

All problem configurations for the compressible flow equations.

Contents

This file collects all Problem policy classes for the compressible flow equations, defined in PDE/CompFlow/CompFlow.h.

General requirements on CompFlow Problem policy classes:

  • Must define the static function type(), returning the enum value of the policy option. Example:

    static ctr::ProblemType type() noexcept {
      return ctr::ProblemType::USER_DEFINED;
    }

    which returns the enum value of the option from the underlying option class, collecting all possible options for problem policies.

  • Must define the static function names(), returning the names of integral variables to be output to diagnostics file.
  • Must define the static function solution(), used for initialization of the computed fields and/or sampling the analytical solution (if exist) at time t.
  • Must define the static function solinc(), used to evaluate the increment from t to t+dt of the analytic solution (if defined).
  • Must define the static function src(), used for adding source terms to the righ hand side.
  • Must define the static function side(), used to query all side set IDs the user has configured for all components.
  • Must define the static function dirbc(), used to query Dirichlet boundary condition value on a given side set for all components in the PDE system.
  • Must define the static function fieldNames(), used to provide the field names to be output to file.
  • Must define the static function fieldOutput(), used to provide the field output.
