While the lattice Boltzmann method can handle both laminar and turbulent flows, it would be important to confirm that FluidX3D can accurately model the specific conditions you're interested in.įluidX3D is a GPU-based software, which means it may require a powerful GPU for large-scale, high-fidelity simulations. The paper mentions conducting the simulation with laminar flow. It's also not explicitly stated whether FluidX3D can handle the overset mesh approach mentioned in the paper, or whether it can simulate the air flows in the ventilation pipes. Free surfaces refer to the interface between the air and the water, which can change shape and position as the ship floods. It's not clear from the provided information whether FluidX3D supports simulation of free surfaces, which are important in ship flooding simulations. If you intend to use the simulation for commercial purposes, you may need to seek a different license or use different software【7†source】. The software is described as being free for non-commercial use. However, there are a few considerations to keep in mind: The software supports particles with the immersed-boundary method, a technique used to model fluid-structure interactions, which could be relevant for simulating the interaction between water and the ship's hull【11†source】.įluidX3D provides visualization options, including slice visualization and surface pressure visualization, that could be useful for visualizing the flooding process and pressure distribution【12†source】【13†source】. The software is capable of computing force/torque on objects, which might be useful for simulating the forces acting on the ship as it floods and sinks【8†source】.įluidX3D has added functions for voxelizing moving/rotating geometry, which could be applicable to a sinking ship scenario where the ship's position and orientation change over time【10†source】. Including prism layers would have improved the modeling of the water-wall friction, but this was believed to be of minor importance compared to the flooding dynamics."""īased on the information gathered from the GitHub page of FluidX3D, it appears that this software has a variety of features that could potentially be used for a ship flooding sinking simulation:įluidX3D uses the lattice Boltzmann method (LBM) for computational fluid dynamics (CFD), which is a numerical approach capable of simulating fluid flow and is frequently used for modeling complex fluid dynamics problems like ship flooding【14†source】. Laminar flow was considered a reasonable assumption since the simulation was performed in model scale. The simulation was conducted with laminar flow and without prism layers to reduce computation time. The model was free in all 6 degrees of freedom. Also the ventilation pipes were modelled and calculations included the air flows. Model scale was used, and the results have been converted to full scale for comparison with the other codes. A mesh of about 3 million cells, using an overset mesh approach with a time step of 0.002 s was used. """CFD results for the Case 3 with Star-CCM+ software. In the case of a sinking ship, you have a tiny breach in a large hull, and it's crucial to accurately model the water flowing through that breach while still efficiently simulating the larger-scale behavior of the ship and the surrounding water.ĭoes this program support extension for adaptive mesh refinement (AMR), or unstructured mesh etc? stl and only keep the 16 watertight compartments and do a 'large scale' simulation. Is this suitable for ship sinking simulation? We all have heard of Sinking Simulator which is 2D particle sim, but there isn't a simple one for 3D etc.įor example get a autocad or 3ds max model of Titanic on turbosquid or whatever, export to.
