RSM: Fluids Tutorial

This tutorial will introduce you to submitting ANSYS Fluids jobs in Rescale through the ANSYS Remote Solve Manager (RSM).

Note: Remote Solve Manager (RSM) is supported only on versions 17.X and 18.1

This tutorial presents an example using ANSYS Fluent. All of this is done without having to leave the Workbench environment.

You can apply the instructions of these tutorials to your own Fluent model, or if you would like you can use the example files for each method. Click on the “Import Job Setup” button to clone the job hosting the file. Click “Save” on the job to have a copy of the file in your Rescale cloud files.

Note: Remote Solver Manager (RSM) is supported only on versions 17.X and 18.1

Currently, to link the RSM tool to the Rescale cloud platform, you will need to setup a Rescale Desktop session.

You can find a guide on how to set up a desktop session here.

Using ANSYS Workbench – Fluent component system

This tutorial will introduce you to submitting jobs from ANSYS Workbench directly to the Rescale platform for a Fluent component system.

To obtain the Workbench project file (.wbpz) used in this tutorial, click on the link below and clone the job hosting the file. Next, click “Save” on the job to have a copy of this file in your Rescale cloud files.

Import Job Setup

Launch a Remote Desktop on Rescale

For this example, please setup a custom Windows Desktop, and attach ANSYS Fluids version 18.0 and the job that you have cloned above (Fluent Submission from RSM), and launch the desktop.

Start Fluids Desktop

RSM Submission

On the desktop, launch ANSYS Workbench through the shortcut found on the Desktop.

Start Workbench
Next, go to File > Restore Archive to import the workbench file that you attached previously. The fluent_rsm_project.wbpz file can be found in the attached_jobs folder found on the Desktop.

Upon restoring the project, you will be asked where you would like to save the project. Save this project outside of the ” Desktops > attached__jobs > jobid-jobname > input” directory such as in the “This PC > Documents” folder.

Set up your workflow like how you would normally do so on Workbench. The example is a 3D model of two fluids mixing in a T-junction pipe. Make sure all pre-processing cells are complete (green check marks). Right click on the Solution cell of the Fluent module and select “Properties”. The properties panel will pop up on the right pane. Under the “Solution Process” section, change the Update Option to “Submit to Remote Solve Manager”, “RSM Queue” to the required core type, “Job Name” to what you want the Rescale job to be called, “Execution Mode” to “Parallel”, and “Number of Processes” to the number of cores you would like to run on.

RSM Fluent properties

Next, right click on the module that requires update and click “Update”, or simply click “Update project” if you set up the RSM properties for the entire project schematic. If you have not already done so, ANSYS, will ask you to save the Workbench project before allowing you to submit solvers.

You can monitor the submission to RSM on the “Job Monitor” tab on the bottom right hand corner of Workbench. Alternatively, you can now log on to the Rescale platform to find a new job on your dashboard.

Fluent RSM Submitted

Once the job has been completed, you will see the screen below. The job (and files) are also saved on the Rescale platform keeping all your jobs/files organized and contained.

Fluent RSM Completed

The Results cell may be in a “Refresh Required” state. To fully load all results and be up to date across the entire Fluent component system, simply right click on the “Results” cell and hit update.
