Ozen Engineering Newsletter – April 2016

Message from your Channel Partner 


metinIt is April already, time to file taxes if you have not already done so! For us, it is also the start of a new quarter along with ANSYS certification. As I may have mentioned this in the past, it is very important for an engineering software company like ANSYS to have quality control for the simulation software products. I have been in this industry for almost 35 years and I have observed that ANSYS has the best quality control among the competition.

What does quality control mean for the end user? It means that we can rely on our FEA & CFD results (provided that boundary conditions are accurate) because ANSYS software tools have been verified and validated. One of the reasons why ANSYS has moved to the #1 position in this industry is the fact that ANSYS has the best quality control. As part of the quality control procedures at ANSYS, the channel partners need to go through a “certification” process with every new release! This certification is done for not only technical but also for sales personnel. So, starting in April through the end of June, we will also be going through “certification” to be able to service our clients, provide them with best support, and give them the most accurate information about ANSYS software products. So, welcome to April, please rest assure that ANSYS is the best engineering simulation software in the market and that we are doing our best to serve you in the most efficient way possible. Please let me know if/how I can be of help with ANSYS software. Have a great April!

What’s New at Ozen Engineering?  

Join Us for Java!

At Ozen Engineering, we love coffee. From a cup of Turkish coffee to a foamy cappuccino, we enjoy it all! In order to brew that perfect cup, we purchased a Jura Impressa C9 One Touch Coffee Center. For those of you that have visited Ozen Engineering for a three-day course, you know that a shot of espresso gives that extra boost to focus and stay alert during those complex simulations. Not a coffee lover? Don’t worry. We also have Persian tea for you tea lovers out there.

At Ozen Engineering, we are known for our superior ANSYS software training led by our experienced engineers. We have engineers traveling from all over to attend our vast array of course selections, including training in ANSYS HFSS/ANSYS Mechanical/ANSYS CFX. Please visit for our current training schedule.

The next time you visit us at Ozen Engineering for a training, Lunch & Learn, or meeting, please don’t be shy and ask us for a cup of java.

Force Based Submodeling 

CanOzcan_VesikalikEven with today’s increased computing power and optimized software, submodeling is a powerful technique to perform analysis on detailed regions of assemblies. Recent versions of ANSYS Mechanical software have easy to use implementation for submodeling, where one can perform cut boundary interpolations all in Workbench environment, without the need of writing good old APDL code.
Submodeling in ANSYS Mechanical (and APDL) is based on interpolation displacements from global level to submodel level at cut boundaries. This approach comes with the assumption that the stiffness of the submodel region does not differ much in stiffness from the global model. This assumption holds most of the time. However, there are cases where one would like to apply structural loads from global model, rather than the displacements. This is especially a requirement when the stiffness of the model is reduced in the modeled sub region. The technique can be also called “Force Based Submodeling”. Below is a naïve implementation of force based submodeling for solid-to-solid case.

Can Pic 1

Need: We would like to apply the force being carried by supports in a submodel, rather than performing a displacement based submodel. The design of the support is changed such that it will invalidate global displacement results. Therefore we propose a way to extract reaction forces at cut boundaries rather than displacements in classical submodeling sense.


  1. Perform global analysis with coarse mesh
  2. Generate a submodel(a.k.a. initial submodel) analysis, with exact same geometry of global analysis with coarse mesh. This will allow one to get reaction forces where cut-boundary displacements are applied
  3. Extract reaction forces on cut-boundary faces
    1. Can extract reaction forces on whole surfaces and apply them as remote forces with deformable boundary option
    2. Can extract reaction forces on each node and apply in final submodel by ensuring same mesh on cut-boundaries between initial submodel and final submodel
  4. Generate a submodel (a.k.a. final submodel) with updated support design
  5. Apply reaction forces calculated from initial submodel
  6. Solve for final submodel and post-process

Example Case#1

I have built a simple model to test the above mentioned concept:

Set 1





Fig. Boundary conditions (a) Global model (b) Initial submodel

When I compare the stress at fixed support surface I get identical Von Mises stress distribution.

Set 2

An APDL code is developed to extract nodal reaction forces from the initial sub model as follows:

The text file generated by APDL code based on “initial submodel”, is then manually copied to solver directory of the “final submodel”. This process can be automized by saving the file to “user files” directory instead.

The content of the reaction force text file is then read into “final submodel” by the following APDL code:

Comparing the stresses and displacements there is perfect match between global, initial and final submodel models.
