Good evening, I did a simulation this time with a 120x60x5 mm tube, I have a 27 mm arrow instead of 37 mm with the 100x50x3 tube. In fact, I just gained only 10mm less on the boom. I wonder if it is not necessary to change the profile.

Ok, I understand better. I took the hypothesis of a localized force on the upper edge of the vertical rectangular tube by imagining that it is the maximum effort, door closed. When a leaf is open, there will also be forces along the X axis. I have not tested. I would have to test with a larger...

So I modified the mesh by taking the max element size to 10 mm. Indeed, the distribution of the effort is not the same, but I find a Displacement magnitude at 37 mm. Did I miss something? I discover Freecad on this domain. I don't really understand the difference between Displacement Magnitude...

Hello, no problem. I am attachiHelng the simulation files on Freecad with also a UPE of 100x55x3 mm. I did the test with a single upright embedded 40 cm in the concrete and a force of 1500 N located on the edge of the upright. This value may be excessive, but I wanted to take into account the...

Hello, thank you.

I am passionate about mechanics and recently I started to get interested in freecad software. I live in the Hauts de France.

Hi all In order to make a metal preframe for a French window as an entrance door, I began to estimate the possibility of building it in rectangular steel tubes of 100 x 50 x 3 mm, laid independently of the walls that could not accept such a load because it was timber framed. The preframe will...
