Cloud computing is becoming more and more popular with the recent changes in the work environment, and Ansys Cloud solution is no exception. While running a Fluent simulation on the Ansys Cloud is now a more familiar task among CFD users since its introduction around a year ago, there are still some cases that might be challenging and need more attention. One of these cases is performing a Fluent simulation using a UDF.
The first thing users might notice when launching an Ansys Cloud Fluent job through the ACT extension is that the UDF files won’t be uploaded, which is why they might see their cases are failing if they don’t pay extra attention. In order to avoid this issue, users must follow one of the options below.
The first and most commonly used method to launch a Fluent job with a UDF is via the CLI (Command Line Interface). With this method, the .c and all other files in the working directory will be uploaded to the Cloud. Then UDF will then be compiled on the Cloud.
Since the Cloud computers already have compilers installed, one doesn’t need to anything special. The local directory should have .c file, case file with UDF plugged-in, and a journal file. As a side note, Ansys Fluent 19.3 and higher supports expressions that can be used to define boundary conditions instead of UDF. Starting with Ansys Fluent 2020R2, the C compiler is built-in with the software. Please refer to the product documentation.
We highly recommend that the user should have the required compiler installed locally to compile, hook, and test the routine before submitting it to the cloud.
If you have not used CLI to submit a Fluent job to the clouds, please read the article below:
In short, you have to open a command prompt (cmd.exe) and navigate to your working folder. This folder should contain all the Fluent input files needed for the run: journal file, case file, etc. Once you login using ansyscloudcli command, you are ready to submit your job on the cloud.
Below is a common example for the commands to run Fluent on the cloud:
> AnsysCloudCLI runFluent -j <job name> [--jou <journal>] -q <queue> [-n <num nodes>] [-m <max cores>] -v <solver version>
-j: job name
-q: name of the queue
(run: ansyscloudcli getQueues, to get a list of all queues. Queue name is case sensitive)
-i: name of the input file for the solver
--jou: journal to execute (if set, -i is not used)
-n: number of nodes
-m: (optional) max number of cores. Useful if you want to make a run with 4 cores on a computer with 16 cores
-v: target solver version
The second method is to compile the UDF locally and upload all files to a virtual desktop infrastructure (VDI) session. Then the compiled UDF can be used with Fluent through the VDI session. Note that the UDF can’t be compiled on a VDI session with versions 2020R2 and earlier.
Lastly, with 2021R1 Fluent has a built in Clang compiler which will allow you to compile a UDF in a VDI session. However, the Clang compiler still won’t allow you to submit a Fluent job with a UDF through the ACT.

Engineering simulation has long been constrained by fixed computing resources available on a desktop or cluster. Today, however, cloud computing can deliver the on-demand, high performance computing (HPC) capacity required for faster high-fidelity results offering greater performance insight, all from the comfort of your home.
Ansys Cloud delivers the speed, power and compute capacity of cloud computing directly to your desktop — when and where you need it. You can run larger, more complex and more accurate simulations to gain more insight into your product — or you can evaluate more design variations to find the optimal design without long hardware/software procurement and deployment delays.

Sometimes if you look hard enough, you find what you need. Ever since people started talking about running large simulation models in the “cloud” our engineers here at PADT have been looking for a good solution. We even offered our own service, and although it was fast and easy to use, we could not make it big enough. Then along comes Nimbix. And they nailed it.
First we asked, are they running on real HPC hardware, not souped up web servers with virtual machines on them? Yes. We found bare metal hardware striped down to fighting weight that is optimized for running simulation.
Then we asked, Is it easy to use or do I have to jump through hoops to just get a job running? Indeed it was easy and powerful. We just wanted to submit jobs and found that the JARVICE™ interface does so much more to configure, setup, submit, and monitor even the most complex parallel solves.
OK, this looked good, but the real test is do we have access to whole machines or is this just a timesharing system with a great interface? Turns out it is not. It is true cloud-based high-performance computing.
We think we found what we were looking for, but we have been burned before. So we did what any simulation engineer would do, we pounded on it with massive ANSYS FLUENT, Mechanical, and HFSS runs. We knew it was real when we were monitoring a CFD run on a mobile phone from a coffee shop in-between customer visits.
We liked it so much that we asked if we could partner with them to offer it to our customers. And that is where we are today with this press release.
PADT is proud to announce that we are able to provide our customers with on-demand HPC resources that are fast, easy to use, and cost-effective. If you are a simulation user who needs to run large jobs, access surge capacity, or just solve faster, Nimbix is the answer. And PADT is here to help determine the right configuration and guide you through the process.
Please read the press release below for more details on what we are doing.

Most Demanding Workflows Offered by PADT in Partnership with Nimbix
Nimbix Cloud Provides Access to ANSYS Applications Through Cloud Supercomputing, Removing the Requirement of Expensive Infrastructure and Hardware
TEMPE, Ariz., July 26, 2018 ─ Understanding the need for easy, affordable and reliable access to supercomputing capabilities, PADT has partnered with Nimbix to provide High-Performance Computing (HPC) in the cloud. The Nimbix Cloud is the industry’s first true Software-as-a-Service (SaaS) supercomputing cloud and will provide PADT’s customers with on-demand, mobile access to more than 15 ANSYS applications without needing expensive hardware and complex infrastructure to support it. Current ANSYS applications available with Nimbix are listed here.
“As long-time simulation users, PADT has always wanted to leverage the cloud for running ANSYS models, but no one could support it before Nimbix,” said Bob Calvin, manager, Simulation Solutions, PADT. “The Nimbix Cloud gives our customers a flexible way to run large models from anywhere and accommodate surge capacity when it is needed.”
The Nimbix Cloud is powered by the JARVICE™ platform, which Nimbix purpose-built from the ground-up to accommodate the most demanding workflows by providing superior performance, capabilities, and ease of use. PADT customers can manage start-up, execution, completion and notifications on full-featured ANSYS applications in the cloud, and send their data from any device including desktop, tablet and smartphones.
“With its global recognition as a provider of numerical simulation and product development, PADT is the ideal partner to leverage the JARVICE platform internally and as an offering to its customers,” said Chuck Kelly, senior vice president, Sales, Nimbix. “Nimbix high-performance computing in the cloud provides a competitive advantage by allowing users to more easily solve complex design problems and then send the data anywhere to turn results into actionable insights.”
“We use Nimbix frequently at PADT because of its reliability and performance when running ANSYS software in the cloud,” said Manoj Mahendran, lead application engineer, PADT. “The platform has allowed us to easily check and submit simulation test results off-site and on-the-go, providing more flexibility to our simulation teams.”
Nimbix Cloud is available today, and PADT invites customers to learn more about the challenges, tools, and mindset needed to run simulation in the cloud, and how the Nimbix platform can be an effective solution, in a webinar on August 8, 2018.
