i am using 2d flutter code using the typical wing section model provided in the su2_cfd in-buit code .i am having problem to compute flutter boundary of a given airfoil. for the given mach no i am getting only one response at a particular mach no i want to plot the three responses (damping , neutral and diverging ) at a particular fixed mach no.can any body help me stating what is the parameter to be changed in the config file to obtain the diffrent response at a particular fixed mach no .

Thank you for your question
You may find some useful information regarding flutter in SU2 at the following thread:

For changing the Mach number, you will want to update the freestream_ values, Mach_number, and the boundary condition values for any "inlet" boundary markers. You should take a look at the config files in TestCases that most closely match your flow conditions to make sure that you are setting the correct set of conditions (for example, the Reynolds number is required in RANS calculations but not in Euler calculations, etc).

It sounds also like you may want to run a sweep of different conditions? If that is the case you may want to take a look at the python scripts in SU2_PY, which will make it easier to run a sweep of different settings.
