Hello
I am working on the efficiency of light carried by a light pipe system. I made a design for it. How many lux will the light in the outside be carried into the room? I’m wondering about this.
I was able to run its design and Grid Based Simulation while using the old version. Then I downloaded the new version. I adapted the gridbased circuit to my own model from the samples in the ladybug-tools-1-4-0 file I downloaded. But “1. Solution exception:Attempted to divide by zero.” Gives a fault. I added the Model JSONSchema file located here Releases · ladybug-tools/honeybee-schema · GitHub to the Update HBJSON component as the file path and made it “true”. But I think something is missing that I couldn’t get updated information.
I am attaching the file and I have two questions.
Where do I make mistakes in the circuit I prepared with new components “1. Solution exception:Attempted to divide by zero” gives this error? Is the circuit correct?
Which of the illuminance values in the EPW file should I consider moved indoors? Which of the values direct_normal_ill, diffuse_horizontal_ill or global_horizontal_ill does the software use when calculating?
I would be glad if you help me. Thank you. newgridbased3.gh (609.3 KB)
Your model is definitely not set up correctly as you are connecting multiple duplicate copies of the same geometry to one model but the error was caused by an edge-case bug in the planarization of your curved window. I just pushed a fix for this planarization case:
If you run the LB Versioner and restart Rhino, you’ll at least be able to simulate this curved geometry correctly.
@chris thank you very much.
I understood the problem, figured out it and got results. Thank you for your help.
But I have a new question. I want to set up the model with Face, not RoomSolid, and set up the grid on the wall surface, not on the floor. For this, I defined the required values for GenPts and SensorGrid. But where can I get the mesh connection required for the Heatmap?
Hello again.
I have one more question. When I run “True” “False” again “True” without making any changes to the PITGrid circuit in my model, I get different light distribution results. Why is this happening?
