It looks like the reason why the measure fails to load is that, somewhere in the measure, the programmer put a parentheses into the name of the input variable (very bad coding practice if you ask me) and Grasshopper seems to be complaining that it cannot support parentheses in component inputs. I would say you have two options to get where you need to:
- Edit the measure .rb file in a text editor and remove the parentheses.
- Add a few lines of code to the OpenStudio Component right after these lines in the component in order to set the coefficients:
And you will replace the
your_velocity_coefficient part of the code with the actual coefficient that you want to set.
