  1. Hi, in order to check the license situation please try first to run the same project in the ProMan GUI version. Alternatively to the WinPropCLI.exe you might use under Windows also the command line interface, see chapter 6.1.2 of the user manual. Best regards
  2. The syntax of the Cells.txt with the unit_impulses SNIR is: Point coordinates x y z followed by the sets of antenna_number carrier_number Signal_level[dBm] SNIR [dB] for each received cell the last set identifies the serving cell. In the Cells.txt with the unit_impulses RSRQ/RSRP it is in principle the same: Point coordinates x y z followed by the sets of antenna_number carrier_number RSRP [dBm] RSRQ [dB] for each received cell the last set identifies the serving cell. Alternatively you can export all the computed network planning results in ASCII files (see check box under the Network tab). Then you will get the RSRP and RSRQ maps which can be loaded in ProMan via the result tree also as ASCII .txt files.
  3. Hi, the observed differences are probably related to the activated filter settings in ProMan. Please disable the filters under Settings => Global settings, both on the Display tab (first line): and under the Computation tab and then try again:
  4. Hi, for the 2020 release the corresponding material sheet is in Example-A03-Database_Materials.zip which is located under: C:\Program Files\Altair\2020\help\winprop\examples\ExampleGuide_models for the 2019 release the corresponding material sheet is in 05_Database_Materials.zip which is located under: C:\Program Files\Altair\2019\help\winprop\examples\
  5. Hello, the wave propagation (radio coverage) results computed in ProMan (using e.g. RunPRO button) are saved in the defined folder under the Propagation tab. If you change the folder name under the Propagation tab before rerunning the simulation with other settings the old results will be still available and not overwritten. So the previous results can be loaded and displayed in ProMan via File => Open Result.
  6. Hi, for providing the antenna pattern to the WinProp API functions please use the following code as shown in the API example projects, then it should work: WinProp_Pattern WinPropPattern; WinProp_Structure_Init_Pattern(&WinPropPattern); /* Definition of antenna pattern. */ WinPropPattern.Mode = PATTERN_MODE_FILE; // Load pattern from file WinPropPattern.Filename = API_DATA_FOLDER "antennas/Antenna.apb"; // Pattern file (including extension) /* Then assign the defined pattern to the Tx antenna */ WinPropAntenna.Pattern = &WinPropPattern; // Use pattern defined above
  7. Hello, in WallMan you can see under Edit => Materials how many objects are assigned per material layer. Under Settings => Local settings you can activate the options "Fill objects" and "Colorize materials" then you will clearly see in the 3D view which materials are used.
  8. Hello Balaji, a short introduction how to use components is given in the ProMan user manual chapter 6.1.7. Generally we recommend to place the TRX (better use TRX instead of Tx & Rx) and the antennas first. Then place the splitters in the next step. And finally connect all the components using cables. The TRX have one input and one output port, you need to select the output por for the cablingt. The splitters have one input port and 2 (or 3) exit ports, so you need to select for the first cable (or the first two cables in case of 1:3 splitter) which exit port shall be used. Best regards, Reiner
  9. Hi, please have a look on the attached WinProp API document which is included in the 2019.2 installation. If WinProp_Predict(see page 35) is called with DataRaysOut structure the ray properties are also computed and returned in the structure WinProp_Ray (see page 224). This includes the complex fieldstrength vectors, however not yet the transmission matrix. This means so far the transmission matrix cannot be written in the .str file via the WinProp API, but you might use the complex fieldstrength vectors instead.

    By default the power superposition is considered in ProMan for the superposition of the individual rays (representing the mean signal level), but also the coherent suerposition (considering the phases) can be activated, which then represents the fast fading (probably the pattern you are expecting). Similar process can be applied for the superposition of the results from two transmitters: Either the power values of the two transmitters can be added, which represents then the expected mean signal level considering both transmitters Or the phases for the superposition can be considered, which would assume that both transmitting antennas are synchronized. In this case the rays from both transmitters can be superposed based on the fieldstrength and phase values given in the .str files (one .str file per transmitter). The .str files can be also generated using the WinProp API.
  11. Hi, using 2019.2 and defining the time instance in the attribute TimeInstance of the class WinProp_Additional we are getting different results for different time instances, i.e. when loading the results in ProMan GUI, both the object and the related shadowing area is moving. Please find attached a corresponding ProMan GUI project with a simple moving box, where the same results can be achieved by using the WinProp API. I was adaping the APIExampleCPPIndoorPropagation and setting the time instance to 0s and 1s. TestSimpleMovingBox_2019-12-09_09-38.zip

    Hello, depending on the option selected under the ray tracing settings either the power contributions of the individual rays are added or the phase is considered (coherent superposition): Results from different transmitters can be also combined in ProMan by loading the first result (.fpp file) and then superpose the second result file .fpp via Edit => Add Data. Please have a look in the WinProp user manual.

    5G set up

    Hello, please use the attached .wst file for the definition of 5G TDD network planning projects in ProMan for frequency range FR2. 5G TDD n257 100MHz.wst
  14. Hello, ProMan can be started with additional arguments passed in the command line in order to load and execute existing projects automatically. The first required parameter, which has to be passed to the command line is the path and the name of the ProMan project file to be loaded. Afterwards the prediction mode has to be specified. Please have a look for further details in the WinProp user manual. The alternative way would be using WinProp via API which is also included in the installation, e.g. under C:\Program Files\Altair\2019_2\feko\api\winprop. Please have a look in the corresponding WinProp API documentation.
  15. Hi, often the files on the C drive are protected, so you should either install the WinProp API package on the D drive or run Visual Studio as administrator.
