Mecway
{{Short description|Finite element analysis software}}
Mecway is a finite-element analysis (FEA) application for Windows. which focuses on mechanical and thermal simulation.Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table 2-5 For thermal simulation, it allows convection, radiation boundary conditions, and temperature dependent thermal properties.Machado 2020 https://doi.org/10.1590/1679-78255662 Structural (mechanical) analysis capabilities are linear static, non-linear static, multi-body contact, dynamic, composite materials, modal analysis and buckling.Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table 2-4Loudspeaker Modelling and Design: A Practical Introduction, Geoff Hill, ISBN 9780815361329 p283 There is also acoustic modal analysis.
Mecway imports STEP files and meshes generated by Netgen and Gmsh and DXF.Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table 2-7Loudspeaker Modelling and Design: A Practical Introduction, Geoff Hill, ISBN 9780815361329 p288
It is low cost or free but limited to 1000 nodes.Loudspeaker Modelling and Design: A Practical Introduction, Geoff Hill, ISBN 9780815361329 p xxxviiiRugdeo http://researchspace.ukzn.ac.za/handle/10413/14827
Usage
The procedure to build a model involves selecting global properties such as "dynamic response axisymmetric", importing or creating the geometry, defining one or more components and material properties for each, applying loads and constraints, and finally solving.Loudspeaker Modelling and Design: A Practical Introduction, Geoff Hill, ISBN 9780815361329 p288-293 A mesh can be created by defining nodes by their coordinates then clicking those node to create elements connecting them, as well as subdividing a coarse mesh by different amounts in each direction.Loudspeaker Modelling and Design: A Practical Introduction, Geoff Hill, ISBN 9780815361329 p294-297Loudspeaker Modelling and Design: A Practical Introduction, Geoff Hill, ISBN 9780815361329 p301 After solving, a deformed view, animation, and exporting to a CSV file are available.Loudspeaker Modelling and Design: A Practical Introduction, Geoff Hill, ISBN 9780815361329 p115

Benchmarks
For a thin shell wall in pure bending, Mecway's deflection and stress were found to have 2% and 6% deviation from the reference solution respectively, compared to 0.02% and 0.2% for ANSYS.Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table E-6Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table E-8
For an axisymmetric pressure vessel, the axial stress reported by Mecway had 0.2% deviation from the reference solution, compared to 0.03% for ANSYS.Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table E-10Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table E-14
For a thick-walled spherical pressure vessel, Mecway's radial and hoop stress at the internal surface were both found to have 1% deviation from the reference solution, compared to 0.05-0.1% for ANSYS.Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table E-16Rugdeo http://researchspace.ukzn.ac.za/handle/10413/14827 Table E-20
