Hey all!
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.
Leave your questions here!
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?
Hi Niels!
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?
Dear Amir,
The errors you are getting seem to be because beaver wasn’t able to locate the karamba.gha file in your machine.
Try moving the Beaver.gha and its .dll dependencies inside the karamba folder.
Also make sure that beaver is being loaded after karamba is loaded.
If you’re able to run the BeaverGetLicense from the rhino command line it is most likely not a license issue.
Hello Renan,
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.
Thanks again ,
Amir
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:

Hi Amir,
Would you be able to add how you resolved this issue? I’m also running on Mac and receiving the same error messages.
Thanks for any help!
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?
Steve Carney
Dear Steve,
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.
Could we recategorize this topic so it is in the Beaver category?
