About the Autodesk CFD process

00:04

Autodesk CFD provides fluid flow and thermal simulation tools that enable you to

00:09

intelligently predict how liquids and gasses will perform in a device or system.

00:14

By using computational fluid dynamics analysis

00:17

to understand these forces and interactions.

00:20

You can make better design decisions that

00:22

reduce energy consumption and improve efficiency.

00:25

The auto

00:26

desk CFD process is made up of five steps.

00:30

These five steps are explained and demonstrated in the CFD,

00:33

Quickstart which you can access from the CFD help pages

00:37

or from within CFD itself on the start learn tab of the ribbon

00:42

step, one begins with AC AD model and at least one flow part also called a fluid part.

00:48

There are several ways to create a flow part in auto

00:50

disk CFD.

00:52

You can create one using geometry in AC AD program.

00:56

You can build volumes that cap the openings so

00:59

that Autodesk CFD creates the flow part automatically.

01:03

Thus making the volume watertight.

01:05

You can use the fluid volume creation tool in auto

01:08

desk fusion

01:09

or you can use the void fill tool in Autodesk

01:12

CFD.

01:14

Once you have AC AD model and at least one

01:16

fluid part built the second step of the process is

01:19

to set up the model by specifying what you know

01:21

about the physical characteristics of the device or system.

01:25

This step includes assigning the materials,

01:29

setting the boundary conditions

01:32

and defining the mesh.

01:35

Now, with the model fully described,

01:37

the third step is to run the simulation which

01:40

operates in a series of small steps called iterations.

01:44

When the results stop changing, the simulation is finished.

01:49

The fourth step is to visualize the results.

01:52

The program offers a robust set of tools that show

01:55

you how the flow and heat move within your model.

01:58

These tools include vectors,

02:01

traces

02:02

plots,

02:03

color shading and value outputs

02:06

iso surfaces

02:07

and more.

02:09

After you have visualized and extracted results,

02:12

the fifth and final step is to iterate and compare other design alternatives.

02:17

Use the decision center to compare your

02:19

results and make informed design decisions.

02:23

Now that you understand the five steps of the auto desk CFD process,

02:27

you are ready to begin learning about some of the ways you can interact with models.
