Hello everyone,

I have been trying to implement a 4th-order Runge-Kutta fluid solver for an FSI simulation using fsiFoam on foam-extend 4.0. However, I run into a compilation error while trying to compile the fluid solver. I am pretty new to C++ programming and I'm not really sure what I am missing.

I have attached the log file of the compilation as well as the .C file. The error is located on line 4.

Thank you
