How to simulate for a series of antenna.azimuth angles in api
Hello, I was trying to simulate with the api of WinPro. When it comes to define the antenna, I wonder if there is a way to input a vector so that multiple angles can be simulated at once. I noticed the variable WinPropAntenna.Azimuth is defined as a double and there's no exmple of it being a vector in the handbook. Thanks…

Can the beams of an antenna at a fixed position be modified during time variant simulation in Winprop?
Hi, I'm trying to do a time variant simulation in WinProp but I only found an example of moving the antenna through a trajactory. I think it's more practical that the antanna site is at a fixed position while the pattern is changing, or rotating. I wonder if there is a method to do so in Proman? Or actually Aman? I also…

WinProp-WallMan
Hello, Where can I find/download the collection of indoor databases/files (Campus.idb, Small.idb, ...) that I can use while I try to learn WinProp and WallMan? These are referenced in the Altair WinProp 2023 Example Guide (08/18/2023) page 14. -Katherine

Settings of the IRT database in WallMan for the V2X
Dear Sir/Madam, I am using your WinProp software, version 2023.1.2, for my research project titled "Analysis of Vehicle-to-Vehicle and Vehicle-to-Infrastructure Communication in an Urban Environment." The area for which I am defining communication is approximately 270 x 270 meters. The main communication occurs within a…

Altair WinProp: What are the wave propagation models supported for urban scenarios?
This article provides a summary of the wave propagation models supported in WinProp for urban scenarios. An urban scenario is typically a built-up area, which could be a whole city, but also a suburban or residential part, a campus, factory, or similar environments. Each building or vegetation object is described by a…

ProMan Propagationsimulation Bandwidth availability
Hello, How can I specify how much bandwidth I have available in a propagation simulation in ProMan? I can set the frequency on which the antenna transmits under the antenna parameters. However, I am missing a parameter for how much bandwidth I can transmit with for my task. Or is this only included in the network…

How to get the correct bistatic RCS file to import Winprop
Hi all, When using winprop to test RIS boost to indoor wifi signal, I need to import the bistatic RCS file into winprop. I built the RIS on the XOZ surface in FEKO according to the angle relationship in the winprop manual (Fig. 1), but the results obtained (Fig. 3) did not agree with the theoretical values; So I used the…

Bistatic RCS of RIS
Hi all I built a RIS with 0 ° incidence and 45 ° exit. I need to get his bistatic RCS file. However, when I did the calculations in FEKO, the results I got were different from the theoretical results. As can be seen from Figure 1, there is a strong RCS at 0°, which is far from the theory. Is there anything I need to set up…

Map error while doing vector map based rural simulation through the API
Hello, We ran into another problem when doing vector DB based rural simulations through the API. After setting the WinProp_Scenario to "WINPROP_SCENARIO_INDOOR" as per Reiner's recommendation (we do this for all vector DB based rural models now, RRT, IRT, SBR, one slope), using the WinProp_Predict_Points() and a .tdv…

The enhancement of RIS to indoor WIFI signal was tested in Winprop
Hi all, As mentioned in the title, I have recently been working on the prediction of the auxiliary channel power of the RIS in the indoor environment. I've tried to simulate RIS using the Consider RCS information from Altair's Proman. But it doesn't work well, so how do I import my RIS into Proman or Wallman?
