Ansys 2020 R1 Slow on the vdi but fine on physical computers in a lab

    • jpickens


      I am the IT tech for Mechanical Engineering for Bradley University. I have installed 2020 R1 on both my in person labs and also on the Universities VDI system. I have been receiving complaints from students that the VDI version is very slow. I had a student come in and he created a simulation in fluent that we ran on both the vdi and in my lab on a physical machine. Running the same simulation in both places the vdi simulation is taking between 1 hour 30 min to a little over 2 hours. The same simulation on the lab machine (Physical Computer) takes under 1 minute to run. We have ran resource monitors and tried changing multiple options including GPU accelerators. Nothing appears to be making it better or worse. I have worked with other techs and the head vdi admin looking at everything from both ends. I built a new app stack and only installed 2020R1 on it to verify that it was not conflicting with other apps in the app stack. Watching the resource monitor the cpu was around 30-35% and the memory never got over 50% and the gpu was between 2%-7%. I also worked with networking and Information Security to verify that i was not having any firewall issues or networking issues. Any help here would be greatly appreciated.
