Simulation Technology in Engineering Curricula: Opportunities
Rajesh BhaskaranSwanson Director of Engineering Simulation
Mechanical & Aerospace EngineeringCornell University
Introduction
• Simulation is getting information about how something will behave without actually testing it in real life – Involves solving complex mathematical models on the
computer– Simulation technology also provides visualization
capabilities for developing physical insightFSAE Race Car Team AguaClara Team
Introduction
• Technology has advanced rapidly– Lowered barriers to simulation– Simulation skills are in great demand in industry
• However, schools are struggling to embed simulation into core engineering curricula– How to make time for simulation in a crowded
curriculum? – Faculty unfamiliar with industry-standard tools– Lack of appropriate content to integrate tools
into courses– Software is evolving
Introduction
• At Cornell, we have made strides in embedding simulation in the curriculum– Teach students effective use– Enhance learning of
fundamentals• Enabled by Swanson
Engineering Simulation Program– Supports one full-time non-
tenure track faculty
Simulation in Cornell Courses
• ANSYS simulation tools are being used in– 10 Mechanical & Aero courses in solid
mechanics, fluid mechanics, heat transfer and numerical methods
– Undergraduate and graduate courses– Lecture and lab courses
• Broad use enabled by the SimCafe wiki

SimCafe Wiki
• Collection of simulation learning modules available for free at simcafe.org
• Contains over 40 modules from courses, project teams and research
• Used in courses at Cornell and other universities• Used by students for supplementary learning• Vision: Grow this into a central e-learning portal
– Avoid duplication and reinvention
SimCafe Module: Example
• Forced convection in a pipe– Heat Transfer lab– Required course– ~ 120 students
• Students compare experiment & simulation

SimCafe Module: Example
• Students learn simulation through tutorial
• Background presented in lab by TA
• Students successfully performed simulation
SimCafe Learning Framework
• Challenge: Students are not just following a recipe
• Strategy: Provide consistent learning structure that foregrounds critical thinking- Being used in ten diverse courses
• Required steps in each tutorial:– Verification & Validation – Pre-Analysis
• Major aspects of “expert thinking” are embedded in these steps

Opportunity
• Students benefit greatly from integration of simulation into engineering education
• Engineering education is changing rapidly– E-learning– Simulation– SimCafe merges both aspects
• Exciting opportunity: Democratization of simulation• Special instructional support personnel are key enablers
– “Director of Simulation”• Other necessary resources: Software, hardware, IT support• Alumni support is critical to enable engineering colleges to
respond to these trends
