  1. Difference Heat maps with many antennas

    Thanks a lot reinerh, your advise worked very well. I sincerely appreciate your help Best regards Balaji
  2. Difference Heat maps with many antennas

    Hi all, Please advise if there is a way in which I can obtain difference heat maps for more than 1 antenna in the prediction rectangle. for Example, firstly load 4 antennas into the prediction rectangle using Edit --> Combine data --> Max value. Then, subtract this combined heat map with another combined heat map with 4 antennas which were already loaded using Edit --> Subtract --> Value (File, Linear) . So Its basically 4 antennas - 4 antennas. Is it possible in ProMan. Please advise Thanks Have a great day Balaji
  3. Loading many antennas results

    Hi all, The ProMan simulation that am currently working on has close to 30 antennas. It feels tedious and frustrating to do 'Edit--> Combine data --> Max value' manually for each antenna every time I run the simulation. Please help me find out if there is a way where all antennas heat maps can be loaded at one go. Thanks Have a great day Balaji
  4. I got the above dialogue (message) when I did try to compare time variant with non time variant. I needed to compare at time instant t=7 and t=13 for example for my application so current time step of t=0 doesn't work. I used DPM propagation model for my analysis.
  5. In my analysis, I observed that, the time variant and non-time variant simulation results are not exactly identical in the entire prediction area (As we would usually expect). I observe sharp differences especially towards the edges of the prediction area. - I tried to view the 4D prediction to confirm whether the models and transmitters are exactly identical. However, my ProMan hanged responding very very slowly. - I also tried to export results and compare, However the time variant simulation's ASCII file is huge (~700-800 MB). This could be because time variant model is exporting data for all time instances. Please advise if there is a way I can find out the reason for differences am observing between time variant and non time variant (exactly identical to time variant) ProMan simulations. One way to understand this is to find out if we can extract data only for the single time instant and/or if we can 3D view to compare the prediction plane (time variant and non time variant simulations) without ProMan hanging. Your help is highly appreciated. Thanks Balaji
  6. in my analysis I observed that, Time variant and non-time variant simulation results are not exactly identical (as we would usually expect) in the entire prediction area. I see sharp contrasts especially towards the edges of prediction area. I tried to view the prediction in 3D, however time variant 3D view is responding very very slow. I tried to export results and compare, however the time variant ASCII file is very huge (~700-800MB). It could be because time variant model Is exporting data for all time instances which I don't need. Please advise if there is a way I can extract data only for single time instant? Also, please advise if I can 3D view the time variant simulation result without hanging my ProMan. Please advise Thanks Balaji
  7. Superposition of results

    In continuation to the procedure explained above, The Edit window provides multiple options to superimpose the heat maps. for example, heat maps can be added, subtracted, multiplied and combined too with max value, min value and mean value as options within combine dialog.
  8. Compare Time variant results with non time variant

    Dear reinerh, mvogel, my apologies, I stand corrected, in my previous comment above, I mentioned that both time variant and non time variant results look identical visually. However, those are not exactly identical in the entire prediction area. I see sharp contrasts especially towards the edges of prediction area. I tried to view the prediction in 3D, however time variant 3D view is responding very very slow. I tried to export results and compare, however the time variant ASCII file is very huge (~700-800MB). It could be because time variant model Is exporting data for all time instances which I don't need. Please advise if there is a way I can extract data only for single time instant? Also, please advise if I can 3D view the time variant simulation result without hanging my ProMan. Please advise Thanks Balaji
  9. Compare Time variant results with non time variant

    Thanks a lot for your kind responses. I can visually interpret that the time variant and non time variant results are identical. However, I plan on exporting results into ASCII and re-compare. I sincerely appreciate your contribution towards my queries. Thanks Balaji
  10. Reposting in India specific forum. apologies for cross posting Hi all, I intend to compare the ProMan results of time variant simulation to those of the non time variant results for every time step. I want to do this to better understand the time variant simulation results. when I perform, Edit >> Subtract data >> Value (file, linear), I get the following error message. "The currently displayed data contains values at the following time steps 0.0000s, 1.0000s, 2.0000s, 3.0000s, 4.0000s, 5.0000s, 6.0000s, 7.0000s, 8.0000s, 9.0000s, 10.0000s, 11.0000s, 12.0000s, 13.0000s, 14.0000s. The data in the selected file contains values at the time step 0.0000s. Currently time step 1.0000s is displayed! but no matching time step found in selected file! Time steps do not match. No operation possible!" please help me compare the results Thanks Balaji
  11. Mobility Modelling in WinProp

    Hi reinerh, I did try the time variant simulation and It worked as expected. However, when I try to compare the time variant result with that of independent non-time variant simulation results with slightly modified geometry. I get the following error message. "The currently displayed data contains values at the following time steps 0.0000s, 1.0000s, 2.0000s, 3.0000s, 4.0000s, 5.0000s, 6.0000s, 7.0000s, 8.0000s, 9.0000s, 10.0000s, 11.0000s, 12.0000s, 13.0000s, 14.0000s. The data in the selected file contains values at the time step 0.0000s. Currently time step 1.0000s is displayed! but no matching time step found in selected file! Time steps do not match. No operation possible!" . Please advise how to compare time variant results and be certain that the values are accurate. Thanks Balaji

  13. Process reports or Run logs

    Thanks a lot Reinerh, I am able to locate the right settings to obtain run logs. sincerely appreciate your help. Balaji
  14. Process reports or Run logs

    Hi All, Please advise whether we can obtain process reports or run logs for the ProMan propagation runs, WallMan Preprocessing, WallMan Simplification etc., Specifically, am looking to note down the simulation times (start time, end time) and RAM status etc., Thanks a lot Balaji
  15. Mobility Modelling in WinProp

    Thanks a lot reinerh, Though I have not tried your advice yet, I plan on doing it this week. From your response, I learnt that this functionality is existing in WinProp. I shall try it out and will reach out to experts when in doubt. Thanks Balaji
