We shall return to the important question of estimating errors due to the discretization process in Chapter 13 and will show that much more precise methods than those arising from convergence rate considerations are possible today. Indeed automatic mesh refinement processes can be introduced so that the specified accuracy can be achieved (viz. Chapters 8 and 14). Discretization error is not the only error possible in a finite element computation. In addition to obvious mistakes which can occur when introducing data into computers, errors due to round-off are always possible.
The error in displacement being reduced to 1/4 for a halving of the mesh spacing. , as O(h) in the plane stress example, where m = 1. The strain energy, being given by the square of the stresses, will show an error of O(h2(p+1−m) ) or O(h2 ) in the plane stress example. The arguments given here are perhaps ‘heuristic’ from a mathematical viewpoint – they are, however, true21, 22 and correctly give the orders of convergence, which can be expected to be achieved asymptotically as the element size tends to zero and if the exact solution does not contain singularities.
