Round 1
Reviewer 1 Report
The article was written clearly without any factual errors. Even the complicated aspects of the model are clearly covered. Congratulations.

Reviewer 2 Report
The authors proposed a new Lagrangian-Eulerian method for simulation of viscoelastic free surface flow. The method is clearly described and the well validated. The proposed method shows capability of reducing computational cost. The reviewer suggests revision of some figures, such as Figure 5, 6, and 10. The lines are overlapping, the authors may want to use symbol to make the results much clearer.

Dear reviewer,
Thank you very much for taking the time to review our manuscript, and thank you for your valuable feedback.
We agree that the Figures 5,6 and 10 could indeed be improved upon to increase the clarity of the comparison. We have therefore updated these figures. Figures 5 and 6 have been updated by adding symbols to display the simulate data, such that they can be distinguished from each other. In Figure 10 we have switched to a different combination of colors as well as dashes and dots such that the simulated and analytic lines can be distinguished more clearly.
We hope that the changes are satisfactory. Thank you again for your feedback.
Best regards,

Reviewer 3 Report
Title: A backwards-tracking Lagrangian-Eulerian method for viscoelastic two-fluid flows
In this paper, a new computational method for simulation of viscoelastic flows is proposed. The method improves the accuracy of the results and reduces the computational cost, both things of capital importance when assessing this kind of engineering procedures. The paper is well structured, and the quality of the presentation is outstanding. In addition, the in my opinion, the methodology proposed for validating the results is adequate and results are impressive. I strongly recommend this paper for publication in Applied Sciences. Only some minor issues should be addressed before publication:
- Please make your conclusions more specific. In conclusion section, the authors should focus only on the main and relevant points. Authors should check for relevant references in the Applied Sciences as these provide continuity for the readers of the Journal.
- I would suggest modifying the lines color in figures 5, 6, 10, 16 and 17. In some cases, especially when lines overlap, it is difficult to identify them. Please, consider using other color sequence instead of black/blue combinations.

Due to your request, we have revised the conclusion section by condensing the text and focusing more on the main points of the paper in a more concise and specific way.
As per your suggestion to check for relevant references in the Applied Sciences journal, we have now added a
reference to the work of Balememans et al. "Sintering of Two Viscoelastic Particles: A Computational Approach", (Applied Sciences 2017).
We hope that the changes are satisfactory. Thank you again for your feedback.
