  1. The first thing to try is to copy the examples to a location where you are certain that there will be no problems with write permissions. (Maybe you had already done that).
  2. It's a pleasure. I sent them to your e-mail address a minute ago through the file-exchange site. The more people use these materials, the better. Warm regards, Martin.

    RSS Values

    Additional observations: when you have two antennas, it is not straightforward to obtain the RSS while taking into account phase differences between the contributions from the two antennas. Network-planning results show RSS based on the contributions from all antennas combined, but it doesn't show an interference pattern. That is because in a general situation, transmitters are far apart and in a complicated environment. To obtain what you are looking for, you can do one of the following: 1. Use a script to manipulate information in the .str file (a detailed output file in ASCII format). 2. If the two antennas are for far apart, use Feko to calculate one combined antenna pattern and use that pattern in WinProp. 3. Perform the entire simulation in Feko if the geometry is not too large in terms of wavelengths.
  4. I sent the tutorials to you a few seconds ago. You should have received an e-mail with a link. Best regards.
  5. The best I can do is copy and paste text from a software-installation expert. "Once you receive an altair license file and tried to use it, however you get a license error 1) You need to ascertain - Is this a standalone (node locked) license file or do you have a server license, To identify if your license file is a server based license or a standalone license, please open the license file in a text editor The difference between a server based license and a node locked license is that in a server based license each feature has a COUNT field. 2) If it is a node locked license, all you need to do is place it in the security folder as you have, in which case, you must check if the Ethernet ID is correct as per below (please delete/uninstall the license manager in this case) also please take care and check for the file extension, i.e. it should be *.dat and not *.dat.dat (this could resolve the issue) Again when you open the license file in a text editor you will see an Ethernet address there in a line that says "ETHERNET = The Ethernet ID is the id of your machine which is exactly 12 hexadecimal numbers. For example D4WRF478F398 Please check your computer’s Ethernet address, by using the almutil -hostid application from the Start > Altair > Tools > Admin tools Menu The listed Host ID should be used to generate the license file. You can also find it by running ipconfig/all in command window and check for physical address under Ethernet adapter local area connection: Alternatively run getmac in command window to find out available Ethernet addresses 3) If it is a server based license, follow the procedure in the attached video to install and use the license manager in the machine whose Ethernet ID is in the license file, 4) If you have a license server running (and if you know the hostname of this license server machine) you need to connect to this server machine by setting an environment variable in your machine, Please set an environment variable to connect to the license server machine as below if using Windows 7 Windows 7 1. Right click on My Computer from the Start menu 2. Choose Properties from the context menu 3. Click Advanced system settings > Advanced tab 4. Click on Environment Variables, 5. Click on new under the system variables section and enter the variable name and value The proper format for a network license location is port@hostname ALTAIR_LICENSE_PATH port@hostname port is the port number. The port number in this command matches with the port number in the TCP_LISTEN_PORT = 6200 line in the altair-serv.cfg file in the licensing folder, changing this port number in the altair-serv.cfg file will allow you to connect using this new port and the environment variables will then need to be set with this new port number. host1 is the host name, this can be the name or the IP address of the servers." Note that there are two different types of licenses, with and without the word "count" in it. The best is to work with a license file without the word "count": just give it the correct name and place it in the correct directory. If your license has the word "count" in it then things get complicated. You'd need to download and install additional software (a license manager) and set up things such that WinProp communicates with it through a "port", even if everything takes place within one machine.
  6. Hi Dujaya, no problem, I have sent them to you. Best regards.
  7. The WinProp Student Edition has a few built-in limitations. Those are listed here: https://altairuniversity.com/feko-student-edition/ One limitation is the number of transmitting antennas. I don't know what might cause the licensing problem. You say it occurs (only?) immediately after system start. Possibly the license server, along with many other programs on the PC, needs time to get loaded and started after you turn on the PC.
  8. I tried it, and it looks like a moving prediction plane is not supported. In WallMan, I was able to combine a real object and a prediction plane into one group and make the group move. However, in ProMan I had the same observation as you had: the prediction on the prediction plane only exists for time step t=0.
  9. No problem. I have sent the tutorials through a file-exchange site. Best regards.
  10. I think the values are practical values, but I don't have a reference. I picked up the values from somebody else's example (presented publicly) and I have used it a few times myself in public examples. It would be wise for you to do an on-line search or literature search for typical values, but if the application is not critical, then these are good values to start with.
  11. In ProMan, under one of the tabs of Project / Edit Project Parameter, you define a prediction plane: a horizontal rectangle at a certain height, by default at z=1.5 m. So you don't need to do anything special in WallMan. To create an additional non-standard prediction plane in WallMan, see the answer at topic 36975:
  12. I think an object is either a wall or a prediction plane but not both. In the attached image, I added a new rectangle to an existing database in WallMan, selected it and edited its properties. The button "Change Type" in the Properties window enables me to choose whether the object will be a regular wall with material properties or a prediction plane. If you want to see results on a particular wall of interest, you could create a prediction plane close to it, e.g. one or a few discretization "pixels" away from it.
  13. I'm attaching an example CADFEKO file in which an anisotropic multi-layer carbon-fiber-reinforced composite material has been defined and has been assigned to an object face. The process starts with defining a few ordinary dielectrics under Construct / Media / Dielectric Medium. Those can then be used to create an anisotropic stack-up of layers under Construct / Media / Anisotropic Layered Dielectric (2D). material.cfx
  14. The .wst files are among the WinProp examples in the installation directory: C:\Program Files \ Altair \ 2019 \ help \ WinProp \ examples. In the 2019 installation they are in 06_Air_Interfaces_aka_Wireless_Standards.zip. In the 2018 installation they are in Standards.zip.
