Welcome to October! We are at full speed ahead in October with many exciting events happening. One of the most important events is the Innovation Conference that we are having on October 13 at the Computer History Museum in Mountain View. You may want to register for the conference here. As Ozen Engineering, we had our first “Western Region Conference” back in 2005 at the same location. Now, after 11 years, we are having it at the same location. This time, we will have a raffle with prizes varying from a brand new Apple watch to free OzenCloud access.
Before the conference, on October 5th, we are having a seminar at our office on “Application Focus: Conduction, Convection, Radiation, and Thermal-Stress”. There is a “lamb barbeque” lunch that follows the seminar which may be why we have quite so many people signed up already :-). You may want to register for this seminar here.
We are also collaborating with Mallett Technology on the East Coast; you may have heard about the latest news. All classes that are listed on our training website are simultaneously being offered in Durham, N.C. The purpose of this initiative is to be able to serve the Mid-Atlantic states.
Please watch out for our next series of seminars on IoT and Additive Manufacturing. We will be discussing the concept of “Digital Twin” if you have not already heard about it which is a great concept when it comes to virtual prototyping and product development enabled by ANSYS Multiphysics Platform.
So, looking forward to serving you in October. Please contact me if I may be of help with your FEA & CFD needs, including mechanical and electrical single or multiphysics. Have a great October!

Fluent Profiles: A Text File as Your UDF
In an advanced software like ANSYS Fluent you often need to specify things in more detail than a constant value. Perhaps you have a radial velocity profile of fully developed flow at an inlet, a time history of mesh motion or an axially varying heat generation. You don’t need to dust off your C++ compiler, though, there is an easier way: profiles.
Say we want to apply the following x displacement over time to a mesh motion:
We can accomplish this with the following text file:
((foil 3 point) (time 0 1 5) (v_z 0 10 10))
Load it into Fluent with the File -> Read -> Profiles menu item and it can be selected like a UDF in the dropdown menu:
It’s that easy.
There are several ways to specify profiles in Fluent but some of the most common are:
A Radial Profile
((<profile_name> radial <n>) (r <r1> <r2> <r3> ... <r_n>) (<field name 1> <f1_1> <f1_2> <f1_3> <f1_n>) (<field name 2> <f2_1> <f2_2> <f2_3> <f2_n>) ... (<field name m> <fm_1> <fm_2> <fm_3> <fm_n>))
An Axial Profile
((<profile_name> axial <n>) (z <z1> <z2> <z3> ... <z_n>) (<field name 1> <f1_1> <f1_2> <f1_3> <f1_n>) (<field name 2> <f2_1> <f2_2> <f2_3> <f2_n>) ... (<field name m> <fm_1> <fm_2> <fm_3> <fm_n>))
A Transient Profile
((<profile_name> transient <n> <periodic? (1/0)>) (time <time1> <time2> <time3> ... <time_n>) (<field name 1> <f1_1> <f1_2> <f1_3> <f1_n>) (<field name 2> <f2_1> <f2_2> <f2_3> <f2_n>) ... (<field name m> <fm_1> <fm_2> <fm_3> <fm_n>))
The above are extremely convenient ways to specify spatially or time varying boundary conditions from analytical or empirical equations. You can easily generate these models with either a text editor or an Excel spreadsheet similar to the the pictured below (save as a tab separated text file)
If you open the Profiles Manager in Fluent, you can write more complex profiles from your solution data, orient profiles to a certain coordinate system and other such operations.
For more information on profiles in Fluent, check out the documentation section at Fluent -> User’s Guide -> Cell Zone and Boundary Conditions -> Profiles. Good luck on making your simulations more accurate!

Antenna Design for Internet of Things (IoT)
By 2020, there will be 26 smart devices for every human being on Earth according to one estimate. IoT will result in an explosion of products with integrated antennas and sensors and world is more connected than ever in IoT age. The number of antennas in our immediate surroundings are increasing every day. ANSYS HFSS offers very advanced features for antenna and wireless designs. Antennas often designed in isolated or ideal conditions. But antenna performance can be very different when mounted on realistic and complex platforms. Antenna radiation distortion, reduced antenna efficiency, antenna to antenna coupling, and multipath fading are just some of the issues caused by the presence of a complex platform with multiple antennas. Using HFSS simulations help engineers to design the antenna and improve integrated antenna performance early in the design cycle within an IoT product.
HFSS is a FEM tool to design and optimize the antenna performance. The new HFSS SBR+ (formerly Savant) shooting and bouncing ray (SBR) electromagnetic field solver can be used to improve integrated antenna performance on electrically large problems such as aircraft, automobile or ship. HFSS SBR takes antenna simulation results from HFSS and provides fast EM analysis of the installed antenna on electrically large platforms.
