Plane Frame 3
Step
This problem has 2 planes of symmetry, so we will cut the model in 2 in order
to:
-Reduce the size of the problem
-Reduce model time
-Introduce a blocking of movement of this plate which is only submitted to
pressure load
00 Problem reduction due to symmetry

Meshing adapted to the geometry
To get better accuracy and be efficient (less number of elements), use adapted mesh

Conclusion
-Always prefer linear quad elements to linear triangle elements
-To get superior accuracy for ordinary displacement analysis, use 2nd order
triangle elements
-For stress analysis, linear elements converge more slowly than for simple
displacement analysis
-> When performing stress analysis, always use 2nd order elements
