Connection type: Radiation

[dynapack]

Great work!

I have played around but have difficulties to Run the model when choosing Connection type: Radiation. Can you help me here?

Thanks in advance// -:)

Can you provide the model input that's failing? You can click "copy model" and paste it into this issue

Hi!

Great with fast response! It’s very easy, it is your simple example model where I just added one radiation connection between the existing nods. After that push the button and wait, but the graph just plot new dots at time 0 and then nothing more happens. If I change the simulation time the graph update just the time axis.

Sounds like you're not running a model that represents a reasonable situation. Here is an example model (also not representing reality) that works with radiation.

Feel free to reopen this if you are making a model that represents a real situation and there is a bug with radiation.

Thanks! It works.
