Graduate Certificate in Computer-Aided Mechanical Engineering

Many engineers today are required to routinely solve complex problems in fluid mechanics, heat and mass transfer, structural mechanics, vibrations, and acoustics, using computational tools such as solid modelers, computer-aided design and computer-aided manufacturing (CAD/CAM) systems, system simulators, and finite element simulation. The proficiency in using such systems enables engineers to model complex engineering design and to analyze problems competently and efficiently. 

The graduate certificate program in computer-aided mechanical engineering is designed specifically to: 

  • train engineers to become professionally certified in the computer-aided mechanical engineering field without formally pursuing a graduate degree. 
  • provide a set of integrated courses on the fundamentals of finite element analysis and CAD/CAM, and 
  • enable students completing the certificate program to understand the theoretical foundations of modeling and analysis of various mechanical components and to conduct performance analysis. 

The program's emphasis will be on fundamentals of analysis and design, which will be supplemented by learning commercially available computer codes such as ProEngineer, Ansys, StarCD, Patran, and Abaqus. 

What are the requirements to complete the graduate certificate program? 

To earn a graduate certificate you must complete 12 credit hours of graduate coursework, equivalent to four graduate courses, and obtain at least a "B" average over all courses applicable towards the certificate. The minimum grade acceptable is "C". Courses with a grade of "C-" or less must be retaken to count towards the certificate. All requirements for the certificate must be completed within three years of admission. 

Specialty Areas 

There are two specialty areas for the certificate program. You may select one of the two following specialties: 

  • Computations of Mechanical Systems 
  • Computations of Fluid and Thermal Systems 

Required and Elective Courses 

There are two required and two elective courses for each specialty area. 

The required courses for both specialties are:

  1. ME 551 Finite Element Analysis
  2. ME 546 CAD/CAM: Theory and Applications

Computations of Mechanical Systems specialty area 

Select two electives from the following:

  • ME 550 Advanced Stress Analysis
  • ME 552 Advanced Applications of the Finite Element Method
  • ME 561 Optimum Design: Theory and Practice
  • ME 563 Mechanical Vibrations
  • ME 569 Mechanical Behavior of Materials
  • ME 558 Composite Materials
  • ME 597 Advanced Mechanical Engineering Projects I

Computations of Fluid and Thermal Systems specialty area. 

Select two electives from the following:

  • ME 505 Intermediate Heat Transfer
  • ME 509 Intermediate Fluid Mechanics
  • ME 525 Combustion
  • ME 552 Advanced Applications of the Finite Element Method
  • ME 581 Numerical Heat Transfer and Fluid Flow
  • ME 597 Advanced Mechanical Engineering Projects I
  • ME 614 Computational Fluid Dynamics

Will any of these four courses count toward a graduate degree? 

Yes! All four courses may be used toward the requirements for a graduate degree in mechanical engineering, if you wish to pursue a formal degree program. 

What are the requirements for admission to the certificate program? 

You must have a bachelor's degree with a minimum GPA of 3.0 on a 4.0 scale and in an area of study, which provides the necessary mathematical preparation for an engineering degree. Applicants with non-engineering degrees, including mathematics, physical sciences, and engineering technology, may be required to take undergraduate mechanical engineering courses before admission to the program. Appropriate work experience also will be taken into account in making decisions about admission. Students will be required to submit a statement of purpose and three letters of recommendation. 

I have completed a few graduate courses in the past. Can I use the credits toward the certificate program? 

If you have already earned credits for one or more of the equivalent courses from another institution or another certificate program, you may request to transfer up to a maximum of three credits of these courses toward this certificate. A maximum of 6 equivalent credit hours taken prior to admission to the certificate program, including 3 credit hours taken from another institution, may be counted towards the certificate. The rest of the courses must be completed at IUPUI within a three-year period from the time of admission. Any waivers or substitutions require approval. No undergraduate courses can be applied to this certificate program. 

How do I apply for admission to the certificate program? 

To apply for admission, contact Valerie Lim Diemer, Coordinator for Graduate Engineering Programs by telephone at (317) 278-4961 or by email:  wvlim@iupui.edu
