Multiple Surfaces_DA Analysis_Mesh results problem

Hi all,

I am doing DA analysis regarding multiple surfaces but the mesh results turned out to be that " Length of the results [X] is not equal to the number of mesh faces [Y]". I tried to flatten the mesh list and join them together. But it still had the same problem.

Can anyone help?

Thanks very much in advance!!!

Attached the gh… The 3dm. file is too big I will try to compress it and upload later.

attached .3dm file


Does the analysis generate any results?

Hi Mostapha,

I attached my partial .3dm. (The parts of interest have been placed into ‘window’, ‘non-glazing’ and ‘testing level’. Could you help me a quick check?

Thanks in advance!!!

Hi Mostapha,

I used another computer to do the simulation again with the same files feed, but the error message was different now. There is no output for DLA but with the warning: index out of range 0. I am really confused now.

Could you tell me what’s going wrong?


Your components are very old. Update to the new version and let us know if that fixes it.


Hi Chris,

Thanks for help! I just come back from the National Labor Holiday. I will let you know if it works well!
