Hi all
I have a problem on sldw simulation that must come from me and can't find the trick.
When I use my sizing excels (beam in 2 simple support with point force), when I analyze an HEA600 on 18.5m span with a point force of 5.5T in the center I find ~24.5mm of deflection, result found on the PSL software of the CTICM, I tell myself that the result is quite reliable.
On Solidworks simu, by taking a beam simplification with on one side a fixed connection and on the other a connection according to reference geometry to leave free rotation and translation in the axis of the beam, or even by switching to volumetric, I come across 34mm of deflection with the same data.
Does anyone have any idea where this large gap can come from?
Thank you

Hello @Jwunder
In simulation, it all depends on the parameters and especially if your beam is in single support or with another type of embedment.
In other words, you have to specify "simple supports" and are you in beam or volume mode?
I suggest you post your piece or at least an image of your simulation settings.
Kind regards

Hello
It is not so easy to model a beam on 2 supports under Simulation.
The simplest way to do this is to block the movement of an edge on the first side of the beam (but not the rotation around this edge).
On the other side, it must be said that the edge is on a plane (which allows this edge to get closer to the first one because of the bending of the beam, but blocks vertical displacements).
With these boundary conditions, the FE calculation should coincide with the theory
