Initializing HFSS


Logging In To Mosaic Linux (for UNC-Charlotte Students only)

UNC-Charlotte students have access to Ansys HFSS on the Mosaic Linux servers.  If you are off-campus, please note that you will first need to sign in to the university VPN, and install FastX, which will allow you to remotely log in to one of the Linux servers.  As I write this tutorial, there are eight available servers, which are listed at the top of this page.  For the purposes of the tutorial, we will be using engr-lcs1.uncc.edu, but feel free to adapt the process to sign into one of the others if you wish. Run FastX. If there is an option labeled lxs-lcs1.mosaic.uncc.edu, double click it. Otherwise, click the + symbol in the upper right corner of the window, choose SSH, and fill in the information shown below, then click Save.

(For UNC-Charlotte students only) Enter your Mosaic password. Once you've done this, you should get something that looks like this:

Click the + symbol in the upper right corner of the window.  Double-click the MATE (VirtualGL) option. This should open a window in which you have a virtual Linux desktop.

Running HFSS

Once you are on a Linux server, open a new terminal (either by clicking the black rectangle on the top menu bar, or by right-clicking on the desktop and choosing Open in Terminal) and enter the following case-sensitive command:
            Hfss

If this is your first time running the program, it will ask you to specify folders in which to save project files.
Once the program opens, click the tab marked HFSS, as shown below:

This should open a new HFSS project.  The main HFSS interface is shown below.

Setting up HFSS: Before you can use HFSS for the first time, there are a couple of items which should be configured for optimal performance.  The configuration outlined here is specific to the UNC-Charlotte computing infrastructure.
    1. On the Tools menu, select Options => HPC and Analysis Options..., click Edit, set the number of cores to 8, and click OK.
    2. In the open window (HPC and Analysis Options), click the Options tab, and ensure that the HPC License option is set to Pool (the default is Pack).
            Your configuration of HFSS should now be complete.
