Error form radiationAnalysis when running Ladybug on Rhino Compute

archicoder · December 21, 2020, 9:43am

Hi all!

I am checking if Ladybug is running with Rhino Compute.
For now, I am running Rhino Compute only on my local machine and I am using it with the example from http://www.github.com/mostaphaRoudsari/hydra_1/tree/master/Radiation_Analysis

The problem occurs with the radiationAnalysis but the rest of the components in that definition seem to work.

I get an error:

I did also ask on the ladybug forum but nobody have responded until now

Can anybody help me with that?

Hey @archicoder, this bug should be fixed in the current Rhino 7.2 release candidate (direct download).

The error above is caused by the plug-in calling scriptcontext.doc.ModelUnitSystem, which in turn tries to get the model units from the current Rhino doc. Compute is designed to be stateless, so there is no current doc, hence the NullReferenceException! In Rhino 7.2, these calls will return sensible defaults. See https://github.com/mcneel/compute.rhino3d/issues/117.

Awesome!

Thank you @will for solving that issue and for a good description of the problem.

I hope you have a lovely rest during Christmas!
Happy holidays!

Hi @will.
Bad news
I got back to it after Christmas, but with Rhino 7.2.20343.11011 I still get an error.

Looks like a different error to me – that’s good news in my book! I’ll see if I can track this one down…

Ah, I hadn’t realised that this example uses the legacy Ladybug. Unfortunately this version of Ladybug has references to Rhino’s ActiveDoc which doesn’t exist in the context of Compute (it’s supposed to be stateless, so there is no “open” Rhino document).

Can you try recreating the same workflow using the new version of Ladybug (v1.x.x)? I had a go and it seems to produce comparable results and it runs without errors in Compute. I’m no expert though!
