Before you start, here's some important information you need to know. </p> <p> </p> <p>In order to run XF:</p> <p>XF can now only run on a windows OS. If you are on a Mac, you can dual boot with windows 10 that is not activated—this still works. The lack of activation gives you minimal contraints, and will not hinder your ability to run XF. Otherwise, you can use a queen bee machine. Note that there are two ways to run XF itself (once you are on a windows machine). You can run via OSC on Oakly--This has a floating license and you will not need to use the USB Key-- or you can use the USB key. Unfortunately, at the moment, we only have one USB key, and it may be best to get an account through OSC. </p> <p> </p> <p>2 methods: </p> <p> </p> <p>1.) If you are not using Oakly— you need the USB key to run</p> <p> </p> <p>2.) Log in to Oakly — you do not need the USB key to run</p> <p> </p> <p>------</p> <p>for method 1:</p> <p> XFdtd you can just click on the icon</p> <p>Will pop up with “need to find a valid license”</p> <p>click “ok” and insert the USB key and hit “retry"</p> <p> </p> <p>For method 2: </p> <p>Log in to Oakly — To log into Oakly follow the steps between </p> <p> </p> <p> ssh in </p> <p>put “module load XFdtd” in command line— this gets you access to the libraries</p> <p>then put “XFdtd” to load it</p> <p> </p> <p>————</p> <p> </p> <p>Note: you must have drivers installed to use usb key. Once you plug it in the first time, it will tell you what to install.</p> <p>Note: The genetic algorithm will change the geometry of the detector and XF will check the gain values with those given geometries. </p> <p> </p> <p>After XF is loaded:</p> <p>Components are listed on the left. Each are different for different simulations. </p> <p>To put in geometry on antenna, click on “parts”. </p> <p>click “create new”</p> <p>choose a type of geometry. </p> <p>Note that you can also go to “file” and import and you can import cad files. </p> <p> </p> <p>“Create simulation”— save the project, and give it a name. Then, click “create simulation”. This stores all of the geometry and settings of the simulation. Now you could, if you wanted to, browse all of the different types of simulations. </p> <p> </p> <p>How to actually run the simulations:</p> <p>In this example, Carl setup a planar sensor with a point sensor inside the sphere, and two more sensors on each side of the sphere. Now, you load the simulation and hit the play button at the bottom. Note that this should take 20 or 30 minutes for it to actually simulate. When it is done, you can actually re-click the play button and it will show you the visual simulation. It will automatically write this out when running the simulations. You either now need to parse that, or be able to view the data in XF itself. </p> <p> </p> <p>You can click “file” ad export data. Additionally, you can export the image. Note that this can give you a “smith chart”; this is that gain measurement you’re looking for. If you had a far field/zone sensor, then you could get a far field gain— which is this smith chart. To get the smith chart, you hover over the sensor, and right click. This should give you the option of a smith chart if you had the correct sensor. Note that all of this data and information is on the right hand side under “results” this will pull up all of the sensors, which you can right click to gather the actual individual data on.  </p> <p> </p> <p>Note: the far zone sensor puts sensors completely symmetrical around the object. Ie if we have a sphere, we will have a larger sphere outside of our conducting sphere/antenna.</p></td> </tr> </tbody> </table> </p><p> </p> Encoding: HTML ELCode plain Suppress Email notification
