Introduction to Fluid Dynamics Engineer Role (FMK)

Agastiya RV, Sr. Application Engineer - Simulation Mar 24th, 2023

If you are a SOLIDWORKS user and want to run a Computational Fluid Dynamics (CFD)
validation on platform, look no further! Introducing Fluid Dynamics Engineer role aka FMK.

A simulation role for engineers who perform routine fluid flow and conjugate heat transfer
calculations to guide design improvements, while exploring innovative design concepts.

With a CAD & PLM-embedded CFD approach, FMK enables users to quickly explore 100s of
designs while concurrently improving product performance based on criteria such as
optimal flow distribution, efficient thermal management, minimal pressure losses, flow
uniformity, reduced recirculation etc. FMK leverages industry standard RANS based finite
volume Computational Fluid Dynamics technology with an integrated and fully guided user
experience tailored for Designers to perform end-to-end product design efficiently on a
single collaborative environment of 3DEXPERIENCE platform.

Let’s have a look in addressing a T-Junction pipe with fluids entering at two different

A MODSIM (Modelling and Simulation) approach is used to address the above challenge.

Using the Collaborative designer for SOLIDWORKS Role, save the CAD on platform.

Once, we click on save, the CAD file will be uploaded and saved on Platform in selected
Collaborative space. Once, the CAD files is saved, the user can launch FMK role through
compass and select Fluid Scenario Creation app. This will launch the CFD Solver on Platform
and give a simulation title.

Setup of a simulation study in FMK

History Tree: Provides the user with all the information that is available and modified during
the analysis.

Action Bar: The action bar is the main command bar, commands that are specific to your
app are organized in sections in this bar.

Assistant Panel: The Assistant is a panel that displays a set of actions that you can perform,
in roughly the order presented, to complete a simulation.

1. Defining Fluid region:

The first step is to define the fluid physics and region along with the fluid material
properties. Since we are using the temperature in the fluids, enable thermal effects and
solid physics. The cube indicates the fluid regions and openings can be used to setup the
boundary conditions. Also, user has to define whether it’s a steady state or transient

2. Defining Boundary Conditions:

The fluid enters the tube at two different locations with two different velocities and at
different temperatures while exiting through the same outlet.

3. Mesh
FMK solver utilizes Body Fitted Mesh.

4. Solve

Solver provides the option to execute the simulation in both local i.e., computer and cloud
computation. The solver can utilize cores like 16, 36, 72 and 144. But by default, the user
can make use of upto 16 cores without any additional costs.

5. Results

Once the analysis is completed, the user can obtain several results like Pressure, Velocity,
Temperature, etc., in the form of contours and XY plots (Graphs).
