Hello dynamo users, I ran through the AU example of a water retention structure, which essentially creates a cylinder geometry then ports that into dynamo as analytical panels. [image] So I decided to throw some supports on and then try add some loads from within dynamo, but ran into the problem…

Hi Arthur, Here is the code for applying a trapezoidal load. Note: in this example I provided a loop because for this particular example I ALWAYS provided a height, which was split into 10 robot elements, then the UDL force at each start/end point was calculated in a spreadsheet and passed into dy…

Which AU example? Might be able to tag the author if we knew which parts you were working off.

Hi Jacob, Thanks for your reply. The class was from Emmanuel Weyermanns “Optimizing Structural Analysis with Dynamo”. ( https://www.autodesk.com/autodesk-university/class/Optimizing-Structural-Analysis-Dynamo-2015 ) The example goes through geometry creation in Dynamo, which is then pushed to Robo…

So far, I did indeed venture down the path of using a python script node which calls the Robot API to create trapezoidal loads (keeping it 2D at the moment instead of moving ahead with panels). The problem now is that I can no longer use the structural analysis for dynamo package (as it does not ha…

Thanks Jonathan! Your thesis is very comprehensive - It’s great that you found a way to work with the custom type and keep using the Structural Analysis for Dynamo package nodes. Excited to dig into your work, will update everyone with how it goes :slight_smile:

Good morning, Could you share with us your code using the ROBOT API for trapezoidal loads? Thanks

Hi Arthur, I did manage to get the trapezoidal loads working - I’m away from my computer atm and will hunt for the code when I can. From memory I used python code node and the robot API. Just a heads up, the add in nodes (I.e. calculate/solve and get results) do not work with loads like this (not …

Hi acam, Thanks a lot for your answer. Yes I would be really interested in both your python code for the load (when you can) and in any helpful guide to use the Robot API. Let me know whenever you find something Thanks again for sharing! Arthur

Hi @acam694 Do you think it is possible to amend the codes you have provided to apply moving load in RSA? Thanks.
