Various specializations under the umbrella of the mechanical engineering discipline (such as aeronautical, biomechanical, and automotive industries) commonly use integrated FEM in the design and development of their products. Several modern FEM packages include specific components such as thermal, electromagnetic, fluid, and structural working environments. In a structural simulation, FEM helps tremendously in producing stiffness and strength visualizations and minimizing weight, materials, and costs.<ref name="Engineering Asset Management">{{cite journal|last1=Kiritsis |first1=D. |last2=Eemmanouilidis |first2=Ch. |last3=Koronios |first3=A. |last4=Mathew |first4=J. |date=2009 |title=Engineering Asset Management |journal=Proceedings of the 4th World Congress on Engineering Asset Management (WCEAM) |pages=591–592}}</ref>

FEM allows detailed visualization of where structures bend or twist, indicating the distribution of stresses and displacements. FEM software provides a wide range of simulation options for controlling the complexity of modeling and system analysis. Similarly, the desired level of accuracy required and associated computational time requirements can be managed simultaneously to address most engineering applications. FEM allows entire designs to be constructed, refined, and optimized before the design is manufactured. The mesh is an integral part of the model and must be controlled carefully to give the best results. Generally, the higher the number of elements in a mesh, the more accurate the solution of the discretized problem. However, there is a value at which the results converge, and further mesh refinement does not increase accuracy.<ref>{{Cite web |url=https://coventivecomposites.com/explainers/finite-element-analysis-how-to-create-a-great-model/ |title=Finite Element Analysis: How to create a great model |date=2019-03-18 |website=Coventive Composites |language=en-GB |access-date=2019-04-05 }}{{Dead link|date=May 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
