Primary LanguageFortranApache License 2.0Apache-2.0

Build Status

Time Marching and Unsteady Discrete Adjoint Sensitivities

Solves ordinary differential equations of the form: $R(\ldots, \ddot{q}, \dot{q}, q) = 0$

How to build and run test case?

  1. Within Makefile.in make sure F90 variable is set to use the fortran compiler that you have. gfortran > 6 is required.
  2. cd src
  3. make 4 ./test_marching

Implicit Time Marching Schemes:

o Backward difference formulas o Adams Bashforth--Moulton o Diagonally Implicit Runge Kutta

Unsteady Discrete Adjoint [unimplemented]
