Is it possible to get restart files in binary format instead of ASCII format?

[Sprotte]

Yes, but you would have to switch to the current develop branch of SU2.
('git checkout develop' before compiling or by downloading it as zip file from the github page, have a look at the drop-down menu.)

Then set
READ_BINARY_RESTART = YES
WRT_BINARY_RESTART = YES

Thanks! I have a quick follow up question.
Is there an "empty" boundary condition in SU2?

[Sprotte]

I have to take a guess here what you mean exactly by 'empty'.

Do you think of something like a "MARKER_CUSTOM_BC" option and a specific place inside the code where you can implement what should be done there?

If so, it's a very nice idea, but I'm not aware of such a possibility.

EDIT: I just had a look into integration_structure.cpp and actually a "CUSTOM_BOUNDARY" is available.

An 'empty' BC would be something analogous to the one in OpenFoam, which basically does nothing (please refer: what does the empty boundary condition mean?.)
I require this because I have changed the boundary conditions at the inlet by modifying the SU2 restart file, and hence in order for it to affect the solution, I need to impose an 'empty' BC at the inlet.

Thanks for your input! I'll take a look at integration_structure.cpp.

Referring to the thread that you linked here, I rather think that 'empty' refers to something like a symmetry BC (a 'no fluxes'-BC). In the SU2 solver's residual formulation (the residuals being the integrated fluxes at the test volume surfaces) this actually translates into 'doing nothing'.

But I'm still not so sure what your idea exactly is, so maybe you should move this question to an own thread.
(My main problem with your question is that keeping prescribed values at the boundaries is something totally different than 'doing nothing' .)
