Physics Set-Up

Define New Material

In the problem specification, a density and viscosity are defined for the fluid flow that do not match those of air or water. A new material must be defined with the properties that we wish to have. Select Material Assignments. In the Material drop down menu, choose Create New. Name the new material “blood” by replacing the bold text at the top of the panel. In the Liquid Properties menu, add Density and Viscosity, then assign them values 1060 [kg m^-3] and 0.0015 [Pa s], respectively.

Boundary Conditions / Forces

First, the inlet must be defined using the Fluid Flow Conditions. In the Add drop down menu by Fluid Flow Conditions, select Inlet. Then, select the largest circular face as the Location and input the Velocity magnitude as 1.5 m/s.

In the same Add menu, define an Outlet for the remaining two circular faces with a Gauge static pressure of 0 Pa.

Next a Wall condition must be added to all surfaces that are not already defined. Wall can be found in the same Add menu as the previous conditions. AIM will automatically assign the Location as every face that doesn't already have a constraint on it.

Return to the Physics panel and press Solve Physics.
