I am an experienced mechanical engineer with more than 5 years of working experience in mechanical design and manufacturing. My expertise are fluid mechanics, thermodynamics, finite element modelling/analysis, thermal plant design, product design, machine design and 3D CAD modeling with Solidworks, AutoCAD, Siemens NX and CATIA. I have successfully carried out so many projects in the fields mechanical engineering and design: 1. Thermodynamics, fluid mechanics, statics and dynamics calculations. 2. Creating 3D models of parts (or/and assemblies) from hand sketches, pictures, diagrams or DWG files. 3. Preparing production drawings of parts/assemblies 4. All kinds of CAD conversions. 5. FEA of parts and assemblies in ANSYS and NX FEMAP, 6. 3D presentations and animations of parts and assemblies.
