Unfortunately, you do not have the license necessary to solve multiple variations of a project simultaneously in HFSS
You will need the license feature called "DSO" or Distributed Solve Option. However, you do have the license to solve multiple frequencies simultaneously!! To set this up you need to go to Options -> General options choose the Analysis tab and add your computer to the list for use for the number of cores you have ( I tend to set up 4 machines with each machine using 2 cores of multithreading). You should be able to search "DSO" in the HFSS help to assist with this setup. If you have issues, PM me and I will give more details to the full setup tomorrow when I am at the workstation and can see the interface

Have Fun
Thank you. Given I don't have a DSO license, so I can't analyze multiple variations simultaneously, how can I solve multiple frequencies at the same time, without running into license issues? I set the following settings
and started a simulation. (The local host is the IP given in the screenshot). So I've put this in 4 times, with the aim of using 4 of my 8 cores. I'm not sure if this is actually working or not on multiple cores, but at least it does the analysis. If I set the IP addresses to machines which don't exist, so it aborts as expected, so HFSS does appear to be using this configuration.
However, if the model has different variations to analyze with the Optimetrics, the analysis does not work sequentially (as before), but aborts when starting the Optimetrics with a license error. (The earlier analysis goes without any problems).
Code:
Failed to check out license 'ansoft_distrib_engine'
Rather annoyingly, rather than just abort, it actually locks up HFSS, so the only way to do anything is to kill the process. (I've had other license issues before, and never had it hang, but this particular license issue causes HFSS to hang).
So I'm not sure if the above changes have actually got multiple frequencies working in parallel or not, but they have resulted in the Optimetics analysis failing, rather than just running sequentially.
I'll PM you as suggested.
I need to find out how best to use the license I have, without trying something which results in simulations aborting rather than running sequentially.
