Hourly Values do not matchup with results file

radiation
#1

I am using Dynamo to run DC grid-based daylight recipe with the type set to 1 (radiation). The calculation runs fine but the query is the numbers i see in the .ill do not match-up with the numbers i see in dynamo for a specific hour.

For one point at one hour i get the following numbers in the various .ill files:
Direct…scene - 3.7296284840000002+03
scene - 9.7137786480000012+03
Sun…scene - 2.8946860830000012+03
Total…scene - 9.7137786480000012+03

while in the Dynamo environment for the same point i am getting the follow:
Total:

Direct:

Would be good to know what happens between when dynamo reads the .ill files and then reports the results.

Thank you in advance

Thanks @mostapha.

so if my understanding is correct: the node in dynamo picks up on the value in Total…scene, divides it by 179 and then that is the w/m2.

i am doing a bit of digging into the python code - cant seem to find where that calculation takes place. This is more for me getting familiar with the honeybee+ code.
