Retrieving Output Files with Distributed Compute Services (DCS)

    • temayer17

      I have been having trouble configuring my DCS jobs to properly retrieve the output files I need.

      I am running Ansys Fluent simulations, where the result I need are stored in report.out files within Fluent's executing directory (dp0/FLU/Fluent). However trying to configure my DCS jobs to find and retrieve this file has been confusing and frustrating due to a lack of good or consistent documentation.

      Some of the user manuals say I just have to add the filename to the "Configuration Workflow", but that never successfully finds any of the files. I suspect this is because they are within the Fluent working directory but I don't know for sure. Other manuals say I need to run the "SYS/COPY" command as a part of my Fluent workflow, but as far as I can tell there isn't any way to run ADPL commands within fluent. Neither, can I find any alternative way to run commands or functions after the end of a simulation in fluent to accomplish this task.

      If anyone has experience dealing with Fluent and DCS, please tell me how to solve this problem; it is incredibly frustrating and I have no way to even approach debugging this.

      Try RSM, instead of DCS

      Hi The reason why DCS cannot fetch your files is probably because they have disappeared. The Workbench update for a design update is not saved by default. There are two workaround to this:
      [A] you tell Fluent to save the output files to a safe certain location where DCS can fetch them. This is then a Fluent scripting question. I cannot answer that.
      [B] you force a Project Save at the end of the Design Point update. To do this, you need modify the Workbench Journal input file that is used for the update. Go to:Design Point Service > Projects > [your project] > Configurations > Configuration.1. Edit "wbjn_Workbench_Project". At the bottom of the file, add "Save()". In this way, you save the project and its files. The Design Point Service can pick up the files.
      I hope this helps!
