Simulations of Fish Swimming
Michele Curatolo, Luciano Teresi, Roma Tre University
Email:
We submit two different COMSOL5.2a models which simulate the swimming of a fish, specifically, the carangiform swimming in a virtual aquarium. The flexural motion of the fish is obtained by using a time-dependent field of distortions, meant to represent the action of fish muscles. Both models make use of both the moving mesh technique and the remeshing feature, and require about 10 Gb of RAM, and more than a day to run. The models are not yet solved (to avoid huge file upload), but are ready to run.
The principal differences between the two models are in the geometry and the activation law for the fish muscles. The model Fish_COMSOL_a.mph is more indicated for robotics applications and runs about for 30 hours, while simulation of Fish_COMSOL_b.mph is more indicated for biology studies and runs for about 50 hours.
It is possible to change the final time of simulation so to have shorter run times, or choose coarser mesh (Remark: fish swimming direction may change with a coarser mesh).
UPDATE: We uploaded the files using the new version of COMSOL. We also submit a new file: Fish_COMSOL53_a_light.mph with a coarser mesh to run faster simulations (computation time ~ 4 hours) but do not trust in the final result.

I's so sad that my comsol can not work the fish-download,because the version is 5.2. |

i am impressed by the model,it give me a chance to the mgaic of the simulation skill and arise my interest to devote my time to do this |

Can I use them directly with 5.3? It seems don't work. |

@photoon We uploaded the files also with the version COMSOL 53. They both worked for me. |

The original code worked and it took more than 3 days. After then, it never succeeded due to memory shortage. My computer with 32GB RAM seems not good enough. Anyhow, the code is great. |

This is nice study. Can you upload the Comsol, 5.2 file. |

I tried lighter version and it seems working well with two and half hours. I wonder whether you can also do that for 5.3b |

@photoon You can write me a private email for the file; there is no enough space to upload another model on the web. |

It is amazing research. I have a question. Where is the moving mesh applied? According to your description, both moving mesh and re-mesh technologies are employed. However, I just see the later in solver. |

It is amazing research! But I can't download from this page due to some network issues. Could you please send me the source files? Thank you very much ! |
