Flow Wizard - How to Set up your Flow Anlaysis:
SolidWorks
Simulation is a versatile software that allows a user to conduct analysis of a
part in a virtual environment. In order
to help the user set up a problem correctly, SolidWorks has a built-in Study
Advisor functionality that guides the user through the process of setting up an
analysis.
Simulation is a large branch that includes
static analysis, thermal analysis, frequency analysis, and also flow. Flow simulation uses computational fluid
dynamics (CFD) to enable the user to run liquid and gas analysis to understand
fluid flow, heat transfer, and forces on component parts. SolidWorks Flow Simulation has the Flow
Wizard functionality, similar to the Study Advisor, to help users set up the flow analysis.
Consider a
simple pipe as shown below. To begin,
let’s select the Flow Simulation tab and select Wizard at the top left.
A pop-up
window should appear for Project Name.
This is where you will be able to enter the project name, comments and
where you can select which configurations you’d like to add to the project
The next tab
allows you to select and set your unit system.
You are able to control the unit of measurement as well as the number of
decimal places shown for each measurement.
The next tab
allows you to choose the analysis type.
This is an important choice. With
regards to the pipe we have modeled, are we interested in fluid flow within the
pipe or are we interested in fluid flow over the pipe? An internal analysis would be considered for
an enclosed flow such as inside the pipe.
An external analysis would apply for an unbounded flow, or blow over an
object. Once you have decided on which
type of analysis you may input additional physical features such as time
dependence, gravity and rotation.
The next tab
allows you to set your working fluid, it may be liquid, gas, compressible,
non-compressible, etc.
SolidWorks Flow
simulation can analyze up to ten fluids of different types provided that you
separate the areas of different fluids from each other.
The next tab
indicates the wall conditions where you can treat them with different roughness
or thermodynamic parameters such as adiabatic.
The next tab
allows you to set the initial conditions of your fluid flow including pressure,
temperature and velocity.
The last tab
allows you to set the result resolution for your flow simulation. This determines the accuracy of the
result. Higher accuracy generally
requires longer runtimes.
The last
step is to complete the wizard which should put you in a good position to start
your flow analysis.
