How to run ANSYS on UCI's HPC

Get Started

1) Request an account

2) Review HPC linux tutorials, HowTo's and documentation

Give the tutorials a serious try if you have no experience with Linux. Go for it!

PLEASE read the HowTo's specifically anything about queues

3) Download and install:

a. X2GO(access cluster) - the is the preferred client

b. WinSCP(file drop)

4) (host name)

Inside X2GO

1) First type ‘q’ (Private queues specify here ‘queue name’)

2) qrsh –q ‘queue name’ –pe openmp ‘# of cores’ (allows you to reserve cores on a queue)

a. qrsh – q ‘queue name’ –pe mpi ‘# of cores’ (WARNING: always tries to take all cores no matter #of cores you type. If max cores not typed it will error out)

3) qstat | grep ‘queue name’ (Find out who is using a queue via username)

4) module load ansys

5) fluent

6) qstat –u ‘username’ (see job number and etc.)

7) qdel ‘job number’ (make sure your job is deleted when done so others can access)

8) exit


Please make sure to:

1. Check the HPC Status Page before contacting support to see if the issue has been documented?

2. If the issue is not documented, then read this.

3. Finally email support at

FYI: Be specific in emails!
