Hello, When attempting to run a CFD simulation in Hyperworks Virtual Wind Tunnel 2019.2, the run almost immediately fails with the following dialog message: Timer stopped because of "JOB_UNKNOWN_STAGE". When looking at the file directory for the run, the only file generated is the AnalysisHistory.info file, which reads: # -------------- Virtual Wind Tunnel Analysis History Information ------------ # This file contains the history information of virtual wind tunnel analysis # NOTE: DO NOT DELETE THIS FILE IF HISTORY TO BE LOADED IN FUTURE Client = Inspire 2019 19.2 11125 Name = Full_Vehicle_CFD_Model_v11_run5 WorkingDir = /home/thavema/Documents/HW/2019/vwt/Full_Vehicle_CFD_Model_v11_run5_9-8-2020_18-36-22 ModelName = Full_Vehicle_CFD_Model_v11 GroupId = 1 StartTime = 9/8/2020 18:36:29 CompletionTime = 9/8/2020 18:36:35 ElapsedTime = 00:00:02 Status = 6 PercentComplete = 100.000000 #END RUN HISTORY --------------- I was thinking that this might be an issue of not enough computing power because it is a large model. Has anyone run into this issue before? Thank you so much for your help!
UltraFluidX, NanoFluidX, Accusolve and Radioss all require a Linux operating system to utilise a GPU or Intel Phi co-processor (UltraFluidX and NanoFluidX only solve on Linux). Has anyone had experience of successfully setting up a Linux operating system to run concurrently with Windows? Altair support advise that Windows is used for pre and post processing, whilst Linux is used to run the solvers. My experience of the last 25 years is with Windows based FEA, Cosmos, Abaqus and Ansys - they all run on Windows. I don't have any experience using Linux and would be grateful if anyone could advise a basic setup to run Linux (I have Centos 7) concurrently or sequentially with Windows 10 and/or Windows Server 2012 R2. My first foray with Linux Centos didn't go well.. Current hardware is a Dell R730 server, 2 x e5-2695 CPU, 384GB RAM + 2 x Tesla K40 or 2 x Intel Phi 7220, plus HP Z840 2 x e5-2643 CPU, 256GB RAM + 2 x Tesla K40. I am thinking to dual boot Windows and Linux on the HP Z840 or install Linux, then create a virtual environment for Windows on Linux. Create studies in Windows and then solve in Linux? applying the same idea to the Dell Server. Has anyone successfully run UltraFluidX and/or NanoFluidX on similar hardware? Cheers, Neil
