Acknowledgements and references

We would like to acknowledge the open-source project FEniCS, with is the basis of turtleFSI.

The numerical schemes in turtleFSI is presented and tested in Slyngstad [1] and Gjertsen [2]. The input problem set up for the TF_cfd, TF_csm, and TF_fsi is taken from the Turek et al. [3] benchmark paper.
