ay be other issues with your geometry, but this is usually the issue people run into.)
Rays will lose energy much more slowly when a room is very reflective, but such conditions only really exist with polished painted concrete. I don't know how many such rooms you've ever been in. I can count them on one hand - and I've been to acoustic reverberation chambers on 3 continents.
Pachyderm works with a ray decimation algorithm. This means that a ray will be traced out to the cutoff time, unless it has lost enough energy that its further contribution to the impulse response is negligible. At this time, the ray is discontinued. So, the more absorption in the room, the less time it will take to run the simulation. So, more realistic absorption coefficients will allow a model to run in a more reasonable amount of time.
Gypsum board/Plasterboard will typically be between 8 and 11 percent at mid and high frequencies, and higher at low frequencies, for example. Concrete, unless polished and painted, is still a little porous, so you can probably make it 3 to 5 percent.
Regarding sources and receivers, adding more receivers adds almost nothing to calculation time (until the every end, when it extrapolates a pressure response, anyway). This is because the receivers are entered into a spatial partition system, which allows it to be done in an optimized way. Adding multiple sources will effectively multiply the calculation time by the number of sources, because the simulation needs to be repeated for each source individually.
Hopefully this helps you figure out how to run simulations with reasonable run times.

ort and export from the images below and also from the HELP file of DB in attachments (Page 71: Importing Geometric Data; Page 78-80: Import 3 - D CAD Data). In their HELP file, they mention about "import geometric data".
However, regarding the input of schedules, loads, constructions and etc., DB normally uses "Component " and "Template" (Page 29: Templates And Components; Page 591: Templates; Page 533: Components). "Templates" are databases of typical generic data, including Activity templates, Construction templates, Glazing templates, Facade templates, HVAC templates, Location Templates, and etc. "Component " are databases of individual data items (e.g. a construction type, material, window pane).
Both "Component " and "Template" are allowed to be imported and exported by using "Import / Export library data" command (.ddf format - DB Database File; Page 734: Import Components/Templates, Export Components/Templates). DB also allows us to build up our own libraries of templates and components (Page 731: Library Management; Page 733: Template Library Management).
In order to import both geometric information and other information related to schedules, loads, constructions and etc. from GH to BD, we supposed the following two ways:
1. GH(HB+GB) --> gbXML (both geometric and "Component " and "Template" information) --> DB
This is the way we most prefer. We did see information related to schedules, loads, constructions encoded in the gbXML file generated by GB, but still do not know the reason why DB did not take this information (I also mentioned this in Q6 within the gh file). We assume this might because the gbXML file we create encodes the schedules based on a different template / schema than the one DB expects. We also post this question to the DB forum for help.
(http://www.designbuilder.co.uk/component/option,com_forum/Itemid,25/page,viewtopic/p,13755/#13755)
2. GH(HB+GB) --> gbXML (geometric information only) + .ddf ("Component " and "Template" information only) --> DB
If the first way doesn't work and DB only takes geometric information from the gbXML, then we might think of the other way - generating the .ddf files from GH(HB+GB) to pass the schedule, load and construction information to DB.
I was wondering if it is feasible for HB and GB to have this function? And what is your suggestion to achieve this?
In addition, we notice that DB can export XML files (not gbXML), so we are trying to figure out if DB also accepts / reads the XML file. If so, we might be able to convert the gbXML (with both geometric and schedule information) to XML. What do you think about that?
Thank you again for all your help!
Best,

l use Rhino 4.0 and corresponding GH version, as a result i could not open your Rhino file.
Hence in your definition as i see,
1) Spring Force-1 -Connection has 11 'inter' components. The inter components do not have any input data and hence 'orange'. What are the inputs for 'inter'?
2) Spring Force - 2 -'Connection'has 1 point component. Rest length & Cut off has 'mass addition' data. This force is also orange, could u throw a light on this please?
3) Pull to surface - both forces has no point input, hence it is orange too. could u throw a light on this too please?
4) There are 2 x Cartesian product components not connected to anything.
I realise that partially it could be because i'm using lower version of Rhino. However, ur input will be highly appreciated.
Kind Regards,

each circle's border, let us say 1.0
3) So, the curve will end up with 5 points, in each point will have a circle, each circle will have a different Radius, but the distance in between the borders of each circle is always the same = 1.0 in this case.
4) The end result list here would be like this to evaluate a curve with these values and find the points on the curve:
List = 1, 5, 11, 19 etc If I use these values to eval a line, I will get the perfect points where I can draw the circles.
…
e now contains (40x3x11=)1320 points with a branch structure of {0-39,0-2} i.e
{0;0}
{0;1}
{0;2}
{1;0}
...
{39;2}
with each branch containing 11 points.
I now want to create lines from the points on line {x;0} to {x;1}, {x;1} to {x;2}, and {x;2} to {x;0}, which will give me a triangular grid on each triangle. How do i do this? I think I need to split the tree 40 times to give me 40 single layered trees but I imagine there's a cleverer way of doing this!
This feel like it should be simple, but I;m having trouble working with the double-layered branch structure. Any help would be greatly appreciated!
Thanks,
Matt…
keep the same number of branches.
The way I'm doing it now has the inconvenience of only working for this particular number of branches, and I would like a more general way. Do I need a script or can I solve it with components, path mapper, etc?
-Also, and this one is probably simple but I can't seem to figure it out: I have a tree structure as in fig B, and I want to pick out certain series of branches from it, for example {1;0} to {2;11}. (PathGen seems to only go from {0;0} to a specified item?) So I want to be able to plug in a choice of numbers, and dispatch those branches into separate trees/cull them somehow. What am I missing? In general, I've failed to find a way to pick out all of the "uppermost" level of branches, eg {3;x}.
Any help greatly appreciated!…
rights to register the "mapwingis.ocx" file.Francesco, would you be patient just a tiny little bit, so that we could try something else? I would be grateful if you could.
1) Close Grasshopper and Rhino2) Run the Revo Uninstaller Pro and uninstall your MapWinGIS application along with removing all the leftovers from the registry.3) Restart your PC, and once it boots again, make sure that you are logged in as an Adminstrator.4) In your Start menu's search box type: "UAC", which will find your User Account Control Settings. Click on it, and a new window will open. Set the bar on the left to "Never notify".5) Turn off your Antivirus, which ever it is.6) Download the 64 bit version of v4.9.4.2 MapWinGIS.7) Right click on downloaded MapWinGIS-only-v4.9.4.2-x64.exe file, and choose "Properties". If there is "Unblock" button click on it, and then click on "OK". If there is no "Unblock" button, just click on "OK".8) Left double click on MapWinGIS-only-v4.9.4.2-x64.exe file and install it to "C:\dev\MapWinGIS" folder. Choose "Full installation" during installation process!9) In your Start menu's search box type: "CMD". Once the "Command prompt" appears do not left click on it! Instead right click on it, and choose "Run as Administrator".10) A command prompt window will open. Type the following command:
"your_regsvr32_folder_path\regsvr32.exe" /u /s c:\dev\mapwingis\mapwingis.ocx
If command does not result in an error message, then type this one afterwards:
"your_regsvr32_folder_path\regsvr32.exe" /s c:\dev\mapwingis\mapwingis.ocx
11) If no error appeared again, then open your Rhino and Grasshopper and check what Gismo_Gismo component prints from its "readMe!" output.If errors appeared, it would be nice if you could post their screenshots.…
