The well know finite element analysis proverb is "Garbage In Garbage Out" there are many many finite element software are entering into the market day by day and there are well established software like Ansys, Nastran, Abacus, etc are also available weather if meshing is done with some parameters and if without changing the mesh parameters and boundary conditions solved in different different analysis software will the results varies due to the mathematical formulations within the software or the result remains same weather anyone has done such experiments kindly share. If any suggestion is asked for FE analysis software selection everyone will say this is best that is best finally will land into confusion but anyone has good experience in that one particular software will recommend that software only I feel for a skilled analyst instead of software he use, can produce the best result do you agree with this
Example- Application in a Hydraulic pump driven by a piezoelectric actuator for use in automotive applications
Detailing a Design into the System-Level Model
- Finite element analysis is useful for designing.
- To find a design that offered the required utility (eg. minimum bending volume, maximum delivery chamber volume, and minimum stiffness,) requires unique tools developed in-house.
- Design of Experiments methods is required to identify the optimal design.

Dear Dr.Krishnan Umachandran
Thanks for the reply my doubt is if the mesh and boundary conditions are same will the analysis results varies from software to software because usually many suggest for one particular analysis should go for the particular software only though other software also have features for analyzing the problem will not be recommendend
Softwares are only tools the skill is in the hands of the Techie. May be iterations using interactive database editing allows users to edit model data simplifies the task of making changes.
I completely agree with Krishnan that softwares are only tools the skill is in the hands of the Techie.

Dear Dr Krishnan Umachandran, Dr.Kamal Eddin Bani-Hani & Dr.Mahfuz Judeh
Thanks for reply
As Dr Krishnan Umachandran listed above various list of software tools with there specializations will there be any difference in mathematical formulations within the software tool can be responsible for obtaining best result in spite of skill of techie
