Hi. I am exploring the potential of Refinery to optimize beam section selections from steel frames. I am using Dynamo and Refinery together with Robot Structural Analysis for this purpose.

The script seems to run fine and the structural analysis too. My issue comes when reading the results in Refinery. The Output results don’t match the values that those Output nodes give in Dynamo. The Dynamo values do match the ones from Robot Structural Analysis. This happens even in really simple cases as the one in the picture attached. (Dynamo gives results in mm and Robot in meters).

Any idea what might be causing this?

Thanks,

Are you on the latest version of Refinery?

FYI @Lilli_Smith

I am running Refinery 0.9.4 and Structural Analysis for Dynamo 2.0.1

I have identified the problem that causes the results to be different.

Apparently, when Refinery starts generating, the load applied multiplies for some reason in Robot, giving different results at different generation times.

I also observed that if I used the geometry as an input, Robot collapsed saying that there were more than one models at the same time and bars were overlapping.
