Getting Started with ANSYS in the Nimbix Cloud
In this article we will show you how to get started using ANSYS in the Nimbix Cloud. ANSYS and Nimbix have deployed the ANSYS software portfolio on the Nimbix cloud platform, offering the highest performance lowest cost cloud solution for ANSYS applications. Nimbix provides unique advantages such as a bare-metal, high performance computing (HPC), fast start-up times, and per-minute billing granularity. We have set up the ANSYS portfolio application environments for you to give you the choice to run the ANSYS application graphical user interface directly in your browser, or in batch mode.
The first step to using the Nimbix Cloud is to create an account. Navigate with browser to https://ansys.jarvice.com. Click Login and when the page refreshes, in the upper right, click Sign Up.
Preparing a License
After you have created your JARVICE account, you will need to contact firstname.lastname@example.org for one-time license set up of Ansys Applications. Once your account has been configured, you will be able to launch Ansys jobs seamlessly.
Each user has a secure data store on the Nimbix Cloud. This is the area where your Nimbix applications will primarily access data, and it is stored persistently between jobs. For further information about data transfer, refer to our JARVICE data transfer guide.
Transferring Data over SFTP using Filezilla
The recommended way to transfer data into the Nimbix Cloud is over SFTP. This is the fastest and most reliable way to transfer data supported by the Nimbix Cloud. First, download the Filezilla Client for your operating system from their website. (Note: Be sure to download the client, not the server).
For SFTP clients, including Filezilla, you will need to configure the connection with the following information:
username: The username with which you login to ansys.jarvice.com.
password: Your API key, which can be found in the settings section accessed in the top right corner of https://ansys.jarvice.com/ once you are logged in. For more questions, see related article Where do I find my JARVICE API Key?
Running Interactive Applications
You can run ANSYS applications in a 3D graphical environment just like you would from your own desktop. The Nimbix Cloud powered by JARVICE 2.0 a powerful remote experience directly in your browser or connecting with a Real VNC client. This is a very useful tool for pre/post processing which eliminates extra data movement back and forth from the cloud. Additionally, you can conduct your simulation work from any location and from any device.
To get started, click the Compute tab and select the ANSYS product you would like to use. You will be presented with options as in the below screen shots.
Once You Confirm your application submission (which shows the actual API call being made to the cloud, you will see a Status message. You will then be directed to your Dashboard.
You will see your job status. Possible Statuses are: Submitted, Processing, Completed, Completed with Error. If you see Completed with Error immediately, it means there may be an issue with your license setup, or input files. Check the output provided in your status email for information on the error.
Click on a Processing job to see details and to connect. You may click the green connect button to use your application directly in the browser. Alternatively, and for better 3D performance, you may use a VNC Client to connect. We recommend Real VNC for the best Ansys experience.
Connecting to Interactive Applications with Real VNC
If you would like a better 3D experience, you may wish to download the Real VNC client. For connection information, expand your job details and press the gray Help button. This will launch a pop up with connection information.
Generally, the connection information is:
password: the password that is set for you job available in the Dashboard.
Shutting Down Interactive Jobs
We recommend that you shut down your application by exiting it from within the environment. You can also terminate your sessions from the portal using the Shutdown button. If your job does not terminate cleanly, you may use the red Abort button. However, this may lead to corruption of your project or data loss. Your job will not terminate if you close the browser or disconnect from your VNC client. You can reconnect and continue your simulation work at a later time. Be sure when your simulation is completed that you have all data written to your /data or My Data folder in the environment before terminating. Finally, be sure not to leave sessions running unnecessarily as this will bill costs to your account.
Running a Batch Job
Launching a batch job is similar to launching an interactive job. However, no green connect button will be displayed while the job is running. To monitor the results of your batch job, press the output button to view the standard output directly from the browser.
Once your data is uploaded (refer to the JARVICE File Transfer Guide), navigate to the Compute tab. Select the Ansys application suite you would like to choose and click a command labeled as Batch.
Each application will present context aware parameters that must be provided to the application for it to properly run. Most ANSYS applications require an Input or Journal file which contain the commands you wish to provide for your particular simulation. Files matching your application’s file input extension will be automatically displayed in the file drop down. To launch the simulation, you will simply need to select your input file and set other relevant parameters, choose the amount of compute scale you require for your run, and submit the task.
Once you have submitted your job and dismissed the Status dialog boxes, you will be directed to your Dashboard. Your task will automatically update from Submitted to Processing once the job starts. If you receive a fast Completed with Error Status, please check your license configuration and/or input or journal files.
A job in the Processing state can be expanded and monitored for convergence. There is a live output which directs the ANSYS standard output to a viewing window as a progress monitor. Jobs that are not converging can be terminated using the Terminate button. Note that if you terminate a running job, only progressive data that has been written as instructed in your input or journal file will be saved.
Once your simulation has completed, you may wish to transfer your results from /data to your local machine. The best way to do this is using Filezilla to download files, the same way they have been uploaded. Please refer to the JARVICE File Transfer Guide for more information.
