A finite element model reports reactions summing to \( 47.9 \) kN against an applied load of \( 48.0 \) kN. This indicates

  • A.Equilibrium is satisfied to within rounding
  • B.A serious error in the model
  • C.That the mesh is too coarse
  • D.That the material properties are wrong

Answer: A

Agreement to about two parts in a thousand is consistent with numerical rounding and reporting precision. A discrepancy of a few per cent or more would instead point to a misapplied load, an unintended restraint or a units error.
