3.9. Support for the Remote Solve Manager (RSM) in Fluent (with Fluent Meshing) Systems

You can run Workbench parametric studies with the Remote Solve Manager (RSM) when using the Geometry and the Fluent (with Fluent Meshing) component systems. For more information about RSM in general, see Remote Solve Manager User's Guide.

RSM Host on Linux

When the Geometry component system is connected to a Fluent (with Fluent Meshing) component system, and the geometry type is set to *.scdoc, you can run a parametric study on both Windows and Linux. Since ANSYS SpaceClaim Direct Modeler files (*.scdoc) CAD geometry files are not supported on Linux, Fluent internally creates a compatible .pmdb file at the same location to be used for the parametric study, irrespective of whether the RSM host's operating system is Linux or Windows. These generated .pmdb files are used only when the RSM host's operating system is Linux. If the RSM host's operating system is Windows, these .pmdb files are still generated, however, they are not explicitly used.

RSM and Parameterization

When running a parametric study, if the geometry type is set to *.scdoc, you should make sure that the Pre-RSM Foreground Update option is set to Geometry in the Parameter Set's Properties panel.

Additionally, when the Geometry component system is connected to a Fluent (with Fluent Meshing) component system (as is required when performing a parametric analysis using Fluent Meshing, you are able to specify two values of processors such that the proper number of processors can be utilized in their respective environments.

  • The Number of Parallel Processors field (when RSM is set as the update method) is used to start Fluent Meshing on an RSM cluster. Otherwise, (if you are not using RSM) then it is used to start Fluent Meshing locally.

  • The Number of Cores for Pre-RSM Foreground Update field is used to start Fluent Meshing locally, when the Pre-RSM Foreground Update option is set to Geometry.

    Note:  The Number of Cores for Pre-RSM Foreground Update field is available even when RSM is not set to be the current update method. If the update method is not set to RSM, then the value of the field is never used. This is so you can first set up the individual cell properties prior to changing the update method. When you later change the update method to RSM, you will then not have to revisit this property. The default value is set to 1 such that it will be used to start Fluent Meshing locally when the Mesh cell gets refreshed as a part of Pre-RSM Foreground Update option.

For example, when the Number of Parallel Processors is set to 32 and the Number of Cores for Pre-RSM Foreground Update is set to 4, Fluent Meshing will be launched with 4 cores when launched locally to execute the meshing workflow until the surface mesh generation task. On an RSM cluster, Fluent Meshing will be launched with 32 cores to execute the remaining tasks in the meshing workflow to generate the volume mesh.
