We are getting many emails with some bug reports and doubts regarding the use of Beaver.
In order to avoid duplicate questions, we are opening up this discussion for future users.

Beaver is currently free! Please read carefully the installation in our food4rhino page.
I’m currently looking at the SLS verification checks in Beaver 1.0.0.7.
Could you explain where the load combinations 1.8G + 1.54Qc are exactly coming from, the factors?
If I understand correctly, the instantaneous deflections are calculated in the characteristic load combination with additional creep calculated with kdef and omega_2 factors to get the final deflection. Are also different load combination/cases like characteristic, frequent, and quasi-permanent taken into account?
And for the limit values, how are they connected and can I change this to my local Annex values somewhere?
your understanding is correct about the quasi-permanent load combinations you’ll find it at the 2.2.3 section at Eurocode 5. So in principle if you apply the same factors to each load case you shall get the final deflections for the quasi-permanent situations.
Characteristic combinations are also calculated, but not frequent ones as they are less critical to the design.
The limit values and factors can be set at the “settings” beaver component to match local regulations. It is available in the latest version in food4rhino, please make sure to upgrade yours.
Hello team,
I am trying to run Beaver on Mac. Is it compatible with Mac?! As I try to install ‘BeaverLicense.rhi’, with ‘.macrhi’ format but once I dragged the file it freezes.
However, I can see a component in GH ‘GetBeaverLicense’. Does it mean that .rhi file is installed?!
As I haven’t receive the licence yet from you can’t tell.
Also I get the errors in the image attached, no matter how many time I reinstalled it. Are the errors showing up because of License problem?
Thank you so much for your response. It is working now, however when I open the example file I get the error:
Solution exception:Object reference not set to an instance of an object.
in the red component. You can see that in the picture attached.
Amir,
I’ve had similar difficulties getting things to run. I solved it today with help from Renan. All the steps I used were as follows:
After installing the plugin via package manager get a license code from Renan and upload it to your online Rhino license account.
Close Rhino.
There is a beaverlicense.rhi file that comes with the install but you need to find it and run separately by double-clicking. Or download it from the food4rhino beaver page and do the same.
Open Rhino (I’m using 7 at the moment but will try it on 8 soon). It seems to then find the license OK. Run KarambaGetLicense and open GH. All my red nodes have now gone.
I have a Karamba/Beaver model which runs fine with several primary load cases. But I’m struggling to see the combinations that Beaver has put together. How to output a list? And how to use the ULS combinator generator?
I have several wind load cases on a structure which need to be treated separately. Is this possible to do?

All the load cases generated can be viewed if you connect a value lists to the TimberFrameView component.
The algorithm will automatically add deadloads together, make all possible combinations of imposed loads and treats windloads and snow loads separetely.
The ViewValueResults should also give you a pretty good idea of which load case is being calculated and which coefficients where used for calculating the member utilization factor.
I’m making first attempts to model joints in Beaver. Is any documentation available? I found the paper presented at the WCTT 2020 and it is most helpful but anything else would be good.
However, I’m having a basic problem with placing connection nodes on to the grasshopper canvas. I get the following error message.
