rural ray tracing question and issue
Hello, My main target is to perform a ray tracing simulation that would account for diffraction and reflection from terrain with a 3D ray tracing simulation. Ground means only terrain, no obstacles like buildings for the moment. This triggers two questions: is it true that SRT does NOT account for diffraction from terrain,…

winprop trajectory heights reference definitions
Hello, I have a trajectory and I wanted to specify it above mean sea level, or independent from the terrain. Switching choice from this menu has no effect and the trajectory is systematically interpreted above ground. What could be the reason? I use v.2026. Thanks, Nicolo'

complex far field source in winprop
Hello, Simulating the propagation of a phased array antenna into a rural environment, I imported the far field from Feko to Winprop Proman. I see that Proman discards information concerning the far field phase. In other words, it retains only the magnitude out of the complex Feko far field data. I could retrive this…

is it possible to show an overlayed map in winprop 2D viewer?
So far one has to go to 3D to see an overlayed map (tiff, or bmp of the area under study). Can this be done simply in the 2D viewer as well?

Problem Generating Vertical Radiation Pattern from .AVA/.AHA Files in Aman
Following the training manual, I am trying to create an antenna radiation pattern from the .ava and .aha files in Aman. As shown in the attached screenshots (I have included both the imported radiation patterns and the patterns generated by the software), the horizontal pattern matches the imported data correctly; however,…

FEKO .ffe antenna pattern import into WinProp - incorrect power results compared to omnidirectional
Hi, I'm trying to import a 2x2 patch antenna pattern from FEKO (POSTFEKO v2025.1) into WinProp (ProMan) as a .ffe file, but the results are incorrect. Situation: In FEKO/POSTFEKO, the main beam is pointing in the Z-axis direction (upward), with a Total Gain of about 13-17 dBi I exported the far field as a 3D_pattern .ffe…

Can I simulate the band at 7 GHz in WinProp - workaround for FR1/FR2 validation error?
Hello, I am running coverage simulations in WinProp / ProMan for a master's thesis on multi-band cellular planning. My current scenario includes three bands working correctly: LTE B8 (950 MHz), LTE B1 (2160 MHz), and NR n77 (3525 MHz). I now want to add a fourth band at 7 GHz, corresponding to the IMT-2030 candidate range…

Missing dll in my installation?
Hello, it looks like my install is missing DBInterface.dll and .lib. I'm using the WinProp API for a large project but I cannot build it due to a linker issuse with those files. I cannot find them anywhere in my installation. Any help is greatly appreciated

Issue generating .mct (Class Definitions) after GeoTIFF conversion in WallMan - Altair Feko 2026
I am seeking assistance regarding a bottleneck in my WinProp workflow. When setting up a new project in ProMan and selecting Rural and Suburban Scenarios (Pixel databases), the interface requires three mandatory files: Topography, Clutter (Pixel database), and Class Definitions (.mct). While I can successfully convert the…

Is a there a way for me to export Z coordinates from a database?
I previously exported X and Y coordinates along with RF Power from a simulation I ran, but I need to export the Z aswell for all X, Y points in the database. I don't mean Z as in my defined solution height, I want the height at every point (height of buildings, vegetation…). Thank you, Carlos

The ground reflection of winprop
Ground reflections in WinProp are very confusing to me. How can ground-reflected paths be obtained in Indoor and Urban scenarios? For example, when I define a horizontal plane, only the direct path appears. Horizontal planes seem to behave differently from the vertical faces of buildings—do they not participate in the…

Winprop question，can Aman convert the phase of the antenna pattern?
I experimented with the converting 2*2D antenna pattern to 3D antenna pattern in Aman, however, I found that the 2D antenna pattern only contains angle and magnitude information, without phase. Does the result of 3D antenna pattern have phase? Can Aman convert the phase of the antenna pattern, or do all the antenna pattern…

Unmatch result in long distance
I build a model of an omnidirectional antenna at 915MHz in a 800m length and arched dome tunnel. The simulation results align with those in papers within the Line-of-Sight (LOS) region, but significant discrepancies arise over longer distances: my simulation results do not exhibit a periodic null points, it's too smooth.…

Load antenna pattern in Proman from WinPropCLI
Hi, I am trying to run a particular Proman project with different Tx antenna patterns using WinPropCLI. A simple code to run the project and save the results worked with: WinPropCLI.exe -F "C:\Users\Documents\indoor_winprop_test.net" -A --results-pro "C:\Users\Documents\Results\Run". But it did not work when I tried to…
