      Try a Google search for Thermal Electric transient Ansys. nI was able to find a good thread discussion on Researchgate.net that covers this analysis type in Workbench.nAs far as your unable to solve any analysis:Sometimes a file or process gets locked after a crash. Try a reboot, then see if a simple cube model solves. Further, try moving your project to another drive/folder and see if it solves OK. n

      Thanks I will look into that article again.nAs for the error, I tried using a simple block before, run on another computer with 2020 R2, create a brand new workbench project and it doesn't work now. I will try to see if changing drives do the trick. Thank you!n

      If the failure occurs on any computer, you may want to see if another user can run successfully.nIn some cases, problems with the Windows user profile or user environment variables cause issues for a given user.n

      I only have one user on my laptop, and the other one I tried was my institute's VM. I will see if I can try this on another computer.n

      Answering my own question, for those with the same problem, try turning off distributed and it might work out.n

      Non-distributed Ansys solver (SMP or Shared Memory Parallel) uses a single Ansys.exe process. Distributed Ansys solver (DMP or Distributed Memory Parallel) launches multiple Ansys.exe(s), the number depends on the # of cores requested. We have had reports of the Distributed solver failing at academic and government sites. The problem was traced to a blocking anti-virus program that was preventing Distributed Ansys from running. It may be worth having your IT department look into the issue.
