Re: [Users] Calling ETK from a C++ code

Dear all,

I am a new user and have run some ETK tutorial examples. Before I begin to do some coding and run my own thorns wanted to ask a general question.

Would be in principle possible to call a thorn from a C++ code like doing

etk_calc(a,b);

or

tmp = etk_calc(a,b);

It would involve a compilation of Cactus together with my code.

I am afraid you can not.

Or

there would be a way to avoid this?

To explain briefly the problem: I have an N-body code which brings 2 Black Holes together and when they are very close I want to do a relativistic calculation of the final coalescence.

Does you N-body code produce any information about spacetime metric? You need to initialize the metric for the fully relativistic computation.

I would suggest that your code dump the final binary orbital parameters to a file and then you use them into the thorn TwoPunctures to generate the initial data you need to continue the evolution.
