As of 2020R1, this exact configuration requires beta features to be turned on. More information here: https://ansysproducthelpqa.win.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/fluent_beta_doc/ch22s04.html?q=pmdb%20rsm. Fluent Meshing requires a .pmdb file when running on Linux, and the .pmdb files will be generated automatically for each design point when beta features is on. If using a Windows cluster, please see the following information. 1. Performing a Pre-Remote Solve Manager Geometry Update https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/wb2_help/wb2h_rsm_prersmupdate.html?q=%22pre%20rsm%20foreground%20update%22 This will run through the design points sequentially (or in parallel if licensing permits it). For each DP, the Geometry will be updated locally, then on the cluster the mesh will be created and Fluent will run. Here, setting Retain Partial Update = Geometry isn’t needed, but you may want to retain the geometries for each DP. 2. Performing and Retaining Partial (Geometry-Only) Updates https://ansyshelp.ansys.com/account/secured?returnurl=/Views/Secured/corp/v201/en/wb2_help/wb2h_partialdpupdates.html?q=%22retain%20partial%20update%22 This method will only generate the Geometry for each DP. Then you can move the project with the saved geometries to the cluster to update the mesh and run Fluent.
