Wind analysis

[JamesWeb012]

Would it be possible to add planes for other levels such as terraces or change the plane height for pedestrian wind comfort.

Also if additional pedestrian wind comfort criteria can be added either for rapid or detailed?

Last thing, if it would be possible to import external tab files for local wind data.

Thanks

Thanks for the feedback. We will consider adding features to help with these things.

About the comfort criteria: Are you trying to use comfort criteria from a standard that is currently not supported in Forma? If so, could you share a reference to it and why you want to use it, so that we may consider adding it as an option?

About importing local wind data: There is an option for importing wind roses, but it currently only supports EPW files. If you can get your data as EPW then you will be able to use it for wind analysis, but we will consider supporting other common wind rose formats. What kind of file format do your external tab files use? Could you share a reference to the format or some workflows where you get them and use them in other software?

for the wind rose,  file format is something similar in the following link

the attached file is a tab file with txt extension 

for the criteria it is according to Israeli standards IS5281 ,
