Method for Simulating Fluids Interacting with Submerged Porous Materials

A computer-implemented method for generating one or more visual representations of a porous medium submerged in a fluid, the computer-implemented method comprising:

• defining a field comprising fluid parameter values for the fluid, the fluid parameter values comprising fluid velocity values and pore pressures;
• defining a plurality of objects comprising the porous medium at locations within the field;
• and
• determining a first set of motion parameter values for the fluid based at least in part on the field, the first set of motion parameter values simulating fluid motion and determined using a grid-based solver based on representations of buoyancy forces and representations of drag forces;
• determining a second set of motion parameter values for the plurality of objects based at least in part on the field, the second set of motion parameter values simulating motion of objects of the plurality of objects and determined using a particle-based solver different from the grid-based solver based on the representations of the buoyancy forces and the representations of the drag forces;
• and
• iteratively coupling the plurality of objects to the fluid based on the first set of motion parameter values and the second set of motion parameter values.
