genCumulativeSkyMtx error

old forum
1

I think i have connected “path” to “_epwfile” of genCumulativeSkyMtx in a right way (set one file path>.EPW file), it still contained a warning of “Download failed!!! You need GenDayMtx.exe to use this component. Please check your internet connection, and try again!” There’s no problem with the internet connection, is there something wrong with “GenDayMtx.exe” ?

Thanks in advance for your help.

Hi Chen,

You need to include the LB-Ladybug component. This is the “brain” of the whole other components.

Hi Chen,

In some cases the firewall doesn’t let the component to download the file.

If Abraham’s suggestion didn’t solve the problem download the attached file and copy it to c:\ladybug and you should be fine.

Hi guys,

me too I have the same problem…I copied gendaymtx.exe in c:/ladybug but it doesn’t work… But it is necessary a web connection! Because I’m working on windows by virtualbox and there I have some probelm with the wireless!!

I have intalled the latest version of ladybug…but the cumulativeskymtx seems to be older (version 0.0.57 and not 0.0.58)

Hi Davide, Did using the newer version of gencumulativesly solved the issue for you? -Mostapha

Hi Mostapha,

I have the same problem too and I am using VER 0.0.58. in the genSkyMtx_Fixed file. The following steps are what I did:

  1. Update Radiance: installed radiance-4.3.a

  2. Download the gendaymtx (21kb) and copy it to c:\ladybug and c:\radiance\bin

  3. Update cumulative SkyMtx component in Grasshopper

However, I still have the same problem, could you check which steps I missed or did wrong? Thank you.

Hui Ling,

You may need to also copy gendaymtx.exe to C:\Users\YOURUSERNAME\AppData\Roaming\Ladybug if you are not an administrator on your computer or you don’t have access to run exe’s from the C:\ drive.

Hi Hanif, Try this:

If you are experiencing any issues with downloading gendaymtx, OpenStudio libraries and other Ladybug and Honeybee files, you can download all the files from this link as a .zip file and manually extract it to Ladybug folder: (https://app.box.com/s/bh9sbpgajdtmmystv3n4).

You can find ladybug default folder by checking the output of Ladybug_Ladybug component. It should be c:\ladybug or C:\Users%USERNAME%\AppData\Roaming\Ladybug depending on your user permissions.

Hi Mostapha…I tried this but still Gencum cant find .mtx file !

thank for your consideration

Hi Hanif,

Did you try to re-run your file after copying the files? In case Abraham’s file runs fine on your system then you are probably making a mistake in setting up your file. Can you upload your file and send a screen capture of the error?

Hi Hanif, Thank you for the image. It is because how you have set up the user folder which has white spaces and '. You need to manually set workingDir_ to a valid address. Try to create c:\ladybug folder and then use a panel to set workingDir_ to c:\ladybug. It should work fine then.

16

Hi mostapha …could you tell me how can i use a panel to set workingDir?! the edit note of panel is off for me! I created c:ladybug folder and extract template files but it works just for Abraham’s file and when i rewrite def it doesn’t work ! thank you

Hanif,

Hard to say Yana,

Attached a working file with the EPW link you used.

This file has more updated components than those that you are using according to your picture.
