    I have decided to calculate my own Mean radiant temperature from my globe thermometer measurements and use that instead of global radiation. This method also avoids problems I was having with the obstacle file because I dont need them anymore.

    I couldnt attach file. Below is the text as seen with a text editor.
    Its a very simple one. The problem seems to arise from the sun location calculation, which sticks at one value when I add the obstacle file.

    Hello
    After a break on other work I have come back to Rayman and sorry to say im still having the same problems.
    It worked very briefly but without any obstacle file. And one of my locations has a lot of trees which I need to model.
    As soon as I introduced an obstacle file, the output fails every time, even when i try again without obstacle file after a total software restart. Im using 3.1 beta. It seems there is a problem with elevation and azimuth.

    Here is a sample of my input

    Date Time Altitude T_air RH Va RAD CLO Metab

    04.07.18 13:10 270 31.9 37.4 2.09 555 0.39 101.5

    And output.

  • Building obstacle file errorsDatum21.02.2019 16:29
    Thema von andyspeak33 im Forum RayMan

    Hello
    OK now I am trying to create my own obstacle file.
    I am using Rayman 3.1 (which to be honest I am finding incredibly full of bugs. I am constantly having to restart it, should I revert to an older version?)

    The latest bug is this:
    I draw several building shapes. When I try to edit them to put a correct Z value in the top corners, as soon as i close the window (click OK) it changes all negative values to positive, thus moving the building and it also changes the albedo and emissivity to 0 even though i did not try to alter these values

    Thema von andyspeak33 im Forum RayMan

    Hello
    I made an obstacle file using shptoobs tool. For some reason the tool wouldnt work for adding trees, no matter how carefully i follow the instructions.
    Therefore, I add the building obstacle file and add the trees manually.
    The output from this is strange though, with a negative elevation and thus error output of 9999.0 in the key output columns. It seems to work OK with my file without trees though.
    I do not have a topological layer because I also spent many hours tearing my hair out trying to get that to work with no success, but my terrain is all flat anyway.

    Any idea why the output gives negative elevation?

    Also, a bug with the tool - it cant seem to decide whether it prefers , or . for decimal point and keeps telling me to change them all, and also I cannot change the albedo value, it just reverts to 0.3 when i click anywhere else.
