***Fatal*** GetSurfaceData: Error discovered, program terminates


I was reading similar topics in the forum but I could be able to fix my problem when I use HB_Annual load. It is about **Fatal GetSurfaceData: Error discovered, program terminates. I do not know the cause of the problem

if someone can help me, I would appreciate it.

Other question is: how I can visualize the results of that energy simulation?

Thanks in advance

Hi @albertomorales ,

Can you upload a sample .gh file that recreates this issue? It shouldn’t really be possible to get geometry errors like that with the latest LBT plugin unless you are doing something very wrong in the setup of your model or your Rhino model units do not correspond to the geometry that you are trying to simulate. What are the dimensions of the building that you have there in Rhino model units?

If we determine that this is the result of a bug in the code, I will fix it.

I am using milimiters.

I cannot attach .gh. a message is displayed saying that new users cnnot do it

this is my email albertoalmolda@live.com so you cn contact me

thanks Chris for your help

can the problem be that my hous is 43 mm large jajajaj?

Yep, I’m sure that is the issue.

EnergyPlus has a fixed tolerance of 1 cm (which no one usually knows about until they try to simulate a model like this because the E+ team hasn’t really documented it). But, long story short, any geometry that is smaller than 1 cm cannot be simulated in EnergyPlus.

If you use the latest version of the plugin, you should get an explicit error about this whenever it happens:

Thanks a lot once again
