Linearized problem

SZhao · January 26, 2015, 06:24

Hi all,

In SU2, there is a option:
% Mathematical problem (DIRECT, ADJOINT, LINEARIZED, ONE_SHOT_ADJOINT)
MATH_PROBLEM= LINEARIZED

In the released TestCases, I found not such demo on how to launch a LINEARIZED CFD case. Anyone has experience running LINEARIZED case? I would really appreciate if someone could send me a such demo.

And I'm wondering what kind of problem it solves. Does it linearize the Euler/NS equation at steady state? If so, how could I extract the standard linear system x_dot = Ax + Bu?

Thanks a lot!

Simon

We have a linearized Euler solver in solver_linearized_mean.cpp, but it is not used very often.
