The simulation of non-Newtonian water flow impact on the rigid barrier in Abaqus- Smooth Particle Hydrodynamic has been investigated. The water is modeled as a three-dimensional solid part with noe-Newtonian behavior. You can see a figure of the assembled parts below
A non-Newtonian fluid is a fluid that does not follow Newton’s law of viscosity, that is, it has variable viscosity dependent on stress. In particular, the viscosity of non-Newtonian fluids can change when subjected to force. In this example, the Us-Up equation of state and definition of the non-Newtonian model in edit input is selected to consider water behavior. The dynamic explicit step is appropriate for this type of analysis because of the SPH method of water. The proper interactions and boundary conditions are used. The mesh should be fine to have many nodes that represent the water behavior
After the simulation, all results such as water wave, pressure, barrier force, velocity, and others are available. You can see some figures for the results below
