Yap it's back now,

Thanks,

hamia;

Thanks for developing this great plug-in.

I have a few questions regarding the thermal analysis component.

In viper component, I can see that direct and diffuse solar energy are available in outputs. Is there anyway to extract the transmitted/absorbed solar energy into the zone?   

Does the one of the Viper inputs, “People”(number of people/m2), take consideration into occupancy difference throughout the day? If so, is it possible to see what the different percentages are? Better yet, is it possible to customize the percentage on hourly basis?  

When would DIVA 2.0 be publicly available? I can't wait to see it.

Thanks.

Hello. I've been looking forward to run DIVA in my computer, but when I drag the DIVA.rhp file to Rhino I get the message that I should get the latest release of Rhino. Nevertheless I run SR8 in Rhino4 with any problems. I have successfully installed all the other components (Radiance, Daysim, etc). I managed to install also the GH components. Could someone help me? Thanks.

Yes, that solved the problem. Thanks.

Hi Jon,

Is there a way to add a slider in the viper component (like the one in DIVA). It can help when running parametric simulations using Galapagos.

Thank you.

Thank you so much.
It worked.

Hi Jeff,

I have an educational version of Rhino SR9 (12-Aug-2010), and I get an error saying I need a newer version. When I click 'check for updates' the webpage states that I have the newest version.

Please advice,

Thank you very much,

Itai

I just installed DIVA for Rhino 1.901. When I open up rhino I don't have the DIVA toolbar, and I can't find it anywhere. Also, when I run any of the DIVA commands, for example, "Metrics" I get a rhino script error: Microsoft VBScript runtime error, Type mismatch: 'info', Line: 41, Char: 16. Any advice? I have Rhino SR9.

Hi Luc,

did you tried this?

Best,

Martin.

Martin,

Yes, those are the instructions that I followed.

Strange, because then you should see the toolbar and so on.

Did you had an error while you were installing DIVA?

Hi Luc ,

you should manually  installed DIVA .DIVA.rhp is located at C:/DIVA folder .

hi everyone, im new in diva so i cant found the problem

from the tutorials i attached the surfaces to the viper component but when i attach to the quick graph nothing occur

grasshopper doesnt give any error

can you help? 

Actually, Viper doesn't depend on the DIVA for Rhino toolbar.  Sacha -- I'm sending you a message so we can troubleshoot.

Brilliant plugin...congratulations! Just the wind analysis is missing ;) DIVA TESTS

Where did it goes wrong? :-)

Hi Thomas,

Check the range of values being produced by the component for solar irradiation and the domain L0 and L1 of the false-color component. If it is at the default of 1, then everything is going to be topped out at blue, try something like 1500.

Hi Ignacio,

could you - or anybody else - be so kind and provide us with a gh-file to get started with DIVA? Especially how to achieve a shadow diagram with overlay of several sunpositions (see 3 posts before, from Igancios DIVA test) would be extremely helpful. Thanks a lot.

Hi everyone,

I'm trying to make the thermal analysis of a Metaball structure.

I modeled it with Grasshopper as a series of patches that follow the curve of the metaball and that work as ext. walls and planar surfaces on top as roofs and one under everything as a slab, all the structure is one single zone...

The issue is that when i run the Viper simulation it responds with an error message: "Geo can't be exported because it contains at least one non-planar surface".

So i checked with the "planar" command but none of the geometry figured out to be non-planar!

Can you please help me?

Thanks in advance,

Hi Stefano,

I'm not sure a single-zone thermal model is the right way to analyze your Metaball structure.  Even if there were no internal partitions, the model would want to be divided into multiple convex zones, which, unfortunately, Viper cannot do.

The non-planarity warning is a separate issue.  In principle, it shouldn't happen if your surfaces are planar. If you post the definition I can take a look.

Jon

Hi Jon,

Thanks again for helping me!

I sent you the Ghs definition attached to this comment: i was trying to find out the problem and i simplified a little bit the shape, but it persist.

I really can't find any issue and Viper worked always perfectly.

I hope you will do!

Thanks again,

Hi, 

Is there anyway that we can calculate Mean Radiant Temperature (MRT) by VIPER?

Thanks a lot

M NICK -- Add the following line to the output control file:

Output:Variable,*,Zone Mean Radiant Temperature,hourly; !- Nickname=MRT [C]

Assuming you have the latest version of DIVA, the output control file will be here: C:\DIVA\Thermal\Grasshopper\IDF_Components\v2.005\02_output_control.idf

After saving the file, the next Viper component you drop on the Grasshopper canvas should have MRT as an option in the Settings form under the Output Tab.

-Jon

Hi everybody,
I just got started with Diva, making the 'default' tutorial.

1. I set up the scene

2. When I press the 'Metrics' button to start the calculation I always get a runtime error>>

________

Source: Runtime error in Microsoft VBScript

Error: Index outside valid range: '[number: 1]' 

Line: 95

Char: 13

Code:

________

I run Rhino 5 Evaluation x64 (I used the file from the 64 bit folder to install DIVA)

Anyone knows, what I do wrong?

Cheers,

Thomas

Thomas,

We would need more information to troubleshoot - Did you already specify a locations, nodes, and material before you clicked the metrics button?  Did you go through the instructions on in the tutorial or use and of the instructional videos? Check out the www.diva4rhino.com site for the tutorial. If you are still getting the error with the DIVA toolbar in rhino I recommend posting a comment in the DIVA for rhino section of the diva4rhino site as this part of the plugin does not use grasshopper, maybe with a screenshot and uploading your model.

Hope that helps,

Jeff

Jon, 

I'm also trying to look at MRT as an output from Viper/E+. I've tried editing the IDF file listed below but found that I was unable to load the Viper component in GH after making the suggested adjustments. I know how to generate the MRT output separate from Viper but it would be nice to parametrically output MRT through Viper. Any thoughts as to why I'm getting a load component error after adding the MRT field to the output file listed below? Thanks

Output:Variable,*,Zone Mean Radiant Temperature,hourly; !- Nickname=MRT [C]

hello, diva i was searching for tutorial but there are very few.. can u send me some links where i can get them.

thank you! 

You can find some great tutorials and user guides here: http://diva4rhino.com/user-guide/getting-started/video-tutorials

thanks!

Hi,

I have a problem with the geometry. It comes as a curved wall to the input on the Diva material component and exits as a simplified straight wall after this component.

Any advise or help?

Cheers!

The component is crudely meshing a nurb surface. Try meshing the curved surface to the desired resolution and then pass the mesh to the component.

Hello. Is it possible to use a translucent glass material in a daylight analysis using Grasshopper? The specific problem I have is that I would like to model a translucent skylight and use grasshopper/diva to test angle variations of shading fins above this skylight on interior illumination levels. As there is no translucent material in the gh diva material component, is it possible to assign a custom material in rhino and then include it in the model which is analyzed when the gh daylight analysis is run? or another way to do it?

thanks

Adam

Adam- instructions for creating a custom radiance material for the grasshopper component are here.

Thanks Jeff. I would like to use the GenericTranslucentPanel_20 material, but this material is not shown in the gh material component even though it is in the material.rad file and accessible in the rhino diva menu. Not sure why it is that I can't get to it in gh. I see in the material.rad file that "The model requires the following two files have been added to a directory included in your RAYPATH variable (c:\daysim\lib or C:\Radiance\lib): rang.cal & Translucent20.dat" I'm not sure if this could be the problem because I only see "rang" in my Daysim\lib and I don't see "Translucent20" in either folder.. Any thoughts on this? I found that someone else had similar problem not seeing the translucent material in the gh menu.. here.. Not sure if they resolved it..

thanks

Adam

Hi Adam,

Hi Jeff. I just reinstalled diva - version 2.1.1.1, but the grasshopper version is still being shown as 2.0.0.7, not 2.0.0.8.  Is 2.0.0.8 included as the DIVA.ForGrasshopper.gha in the C:\DIVA folder? I copied this into my gh components folder, but I'm still seeing 2.0.0.7 as the component version, not sure why..

Adam -- 2.0.0.7 is correct.  I think Jeff got a little ahead of himself.  :)

Hi everyone, I was wondering if Shaderade has been incorporated in the latest Diva versions?

I have found a similar question asked on November 2012 without a clear answer. Could you please inform me with anything related to the Shaderade component?

Hello Jeff Niemasz Awesome Plugin, but I've a little problem that the thermal analysis takes longer time than it should. It always stops at Initializing simulation for about 20 minutes. There's any way to make take less time. the shading element consists of like 12 planar surfaces, so as mush as i guess no modeling problem. Let me add when I only test one planar surface it runs quicker

Thanks in advance

Hello every one, I've a little problem concerning Thermal simulation, when I add the surrounding context as a berp beside the facade elements as  a shade it runs the thermal simulation twice, giving me two results of everything. Any clue what might be the problem!!

@Israa El-Maghraby

Try Flatten the ground before Connecting to shades

@ Mohamed hegazy, Thanks in a million I will try that now (Y)

Hello all,

I'm quite new at grasshopper and DIVA.

I am trying some irradiation simulations for my thesis on a simple geometry and I am getting some really strange results. The north oriented surface of the roof  is getting higher results than the south one (for city at north hemisphere). Can anyone guess the reason, or did anyone face this problem in the past? what do you think I should change?

Attached you may find the .gh file and the climate data file.

Thank you for your time.

Hello, 

Is there a way to automate the annual glare analysis in Grasshopper?

Thanks,

Thomas

Hi, I'm new to Diva in grasshopper and now working on some simulations about illuminance. 

When I press button and run it, I saw the message saying, "Starting raytrace on 4 grids...

generating octree

octree complete

starting raytrace"  and didn't work.

What is happening in Diva?

Does anyone help me?

Thanks.
