If you turn on the TV or browse the internet these days, automation is a familiar topic. From smart homes to learning thermostats, the drive to save time and effort by automating repeated tasks is everywhere. We use words like ‘smart’ to indicate that our devices are no longer one-size-fits-all but instead adapt and can be programmed to better suit our needs and behaviors. So, too, should be the case with our engineering software! That is why we have spent over a year to add scripting, a broadly applicable interface for automation and customization of modeling, to the ANSYS SpaceClaim geometry modeling environment.
In a previous blog post, we introduced SpaceClaim scripting and how it can automate repetitive or tedious tasks. With ANSYS 18.1, we’ve taken it a step further and made it easier to share and use SpaceClaim scripts outside of the editing environment. By publishing scripts to dedicated buttons in the user interface or calling them from within a Workbench script, you can now use the power of scripting in more places than ever before. Furthermore, we have extended the interaction with scripts to allow for user input of selections and values during execution. Let’s take a closer look at these improvements. Continue reading
Pipe exist everywhere. There are a wide range of applications involving pipes. For daily life, pipes are used in the water line for our house, the air conditioner of the car we are driving, and in the gas station where the gasoline and diesel are transported. Industry-wise, a lot of pipes are used for processing, gas and liquid transmission, transmission as well as extensively in power plants. power plants.
From a structural analysis point of view, a pipe is a slender structure with a tubular cross section that could be very long along the length direction. A beam can also have tubular structure, but most beams or columns are used for strength purposes. The dominant function of the pipe is used for transporting fluids and gases. The liquid/gas transporting could be hot, under high pressure, and also be viscous. We want to use a minimum pipe thickness to save material while still satisfying the temperature and pressure requirements. Continue reading
My friend, a fellow Romanian, just told me a funny story. She just relocated to the U.S. and was asking her dentist “When will I have the root channel treatment?”. The dentist kindly replied “Did you mean root canal, my dear?”
Human kindness is a beautiful thing. As a software developer, I often wish that computer programs would be equally technically kind. Most of them are not. Many times, when a user mistypes a command, applications crash. Continue reading
ANSYS Fluent 18 has advanced erosion fluid dynamics modeling by adding three industry-standard models to the previous default model.
Erosion wear is the loss of material due to repeated impact of solid particles on a surface and causes major economic losses across diverse industries such as oil and gas, hydraulic transportation, and chemical processes. Erosion severely damages flow passages, valves and pipe fittings, leading to higher replacement costs as well as the loss of valuable production time. For example, some oil and gas fittings can fail after just 30 minutes of operation due to high erosion rates! Engineers need to quickly evaluate the erosion on dozens of design variations to find ways of stretching the part’s lifespan in order to reduce costs and maximize process up-time.
For over 40 years, ANSYS training has been a reliable partner for engineers to increase their productive use of ANSYS software. With tight deadlines and demanding product design requirements moving CAE engineers into the spotlight, engineers are feeling the pressure to deliver accurate predictions of product performance in a timely manner, often times before a product is even built.
Project and product success ultimately hinges on the preparedness of the engineering team to perform the simulations necessary to support key engineering decisions. In an environment of evolving demands it is becoming a high priority for engineers to keep their skills current. Successful engineers therefore focus on learning more in order to stay on top and to move ahead. Continue reading
We just held our eighth ANSYS in ACTION session. This one featured HPC on the Cloud and showed the audience how engineers without local HPC resources can access ANSYS and HPC in the cloud.
For those of you new to the series, ANSYS in ACTION is a webinar series where we show you how easy it is to solve common applications and address common challenges engineers face using ANSYS software in just 20 minutes on Thursdays at 1 pm ET. We skip the marketing and the background information and get right to the demo. Continue reading
If you’re an engineer who has dealt with large simulation models, you know there’s often a trade-off between accuracy and solution time. Submodeling is a technique you can use to reduce solution time without sacrificing accuracy of results.
A common strategy you can use to look at the overall behavior of an assembly or complex part of a large model is to simplify the model during preparation by removing small details, like fillets and holes. Simplifying models in this way can have a significant impact on run times. This simplification, while not excessively affecting overall model stiffness, may result in lower resolution of localized stresses. What you need, then, is a mechanism that allows you to “zoom in” on these details to examine behavior around specific areas.
Over the past year and a half, our team has been creating a large number of technical ANSYS videos that focus on a variety of areas. From ANSYS Electronics to ANSYS CFX, ANSYS Fluent to ANSYS Mechanical, ANSYS SCADE, and even ANSYS Student tips for those just getting started in the art of engineering simulation.
Today, I’d like to share a few of the examples you’ll find before I send you off to explore on your own. Continue reading
Being a CAE analyst for almost 20 years has been an interesting journey. Looking back to see the huge development in computer power and the development of the simulation software, in terms of supported physics, features and ease of use, is very pleasing. The turnaround time for a typical simulation has been reduced from months to days. However, there is one part of the process that has not changed, and not gotten the same speed up; namely reporting. Continue reading
In 2013, I wrote a blog showing ANSYS users how to make MATLAB apps for ANSYS Fluent. Just as a quick reminder, a friend of mine, who is also an ANSYS Fluent and Mechanical APDL user has a Windows Matlab code programming a Linux Fluent session. She had just updated her hardware. Everything is moved to Linux. She also needed to integrate a Mechanical APDL session.
She was asking me: “Why, can’t I port my MATLAB® code running on the platform of my choice and be able to also connect to Mechanical APDL?” She challenged me to to create a less than 20 lines code example. Back in 2013, my example was for ANSYS 16.0. Here is my update for ANSYS 17.0. Continue reading
