Results of the analysis are not equal between 2D and 3D mesh

I created an object of size 10 x 0.1 x 0.5 meters (Figure 1). One side of the object is completely fixed to the other side of the object, a force of 1000 N (Figure 2). The analysis in Figure 3.

Figure 1

Figure 2

Figure 3

 

I want to check the results of the analysis on the example of 2D model. I drew a rectangle 10 x 0.1 meters. Next, apply a force to one side and fixed the other side. Set "Thickness" = 0.5 m in the "Element Definition" (Figure 4). The results are shown in Figure 5.

Figure 4

Figure 5

 

Why the analytical results of the two different? What did I do wrong?

Hi DenPopov,

 

Very good presentation! You covered just about all of the questions that could be asked. :-)

 

I think the problem is that your 2D model appears to be in the XZ plane. The software needs it to be in the YZ plane. In fact, I'm surprised you were even able to get results! I have seen instances where one node with a nonzero X coordinate stops the analysis.

 

So either rotate the lines into the YZ plane, or start the modeling over again.
