B6- Eureka Court, Beside BATA, Behind Chermas, Ameerpet, Hyderabad, AP, IndiaPh.55615442, 55625442, 55635442, 56565442, 56645442, 55775442, 55325597, 23755770, 23755774.
ANSYSis a complex software to teach/ learn, as it involves lot of FEA/ Structural/ Thermal Engineering/ Mathematics subject to a higher levels and so, Engineerswith specialization in Structural, Thermal, CADCAMCAE, Engineering designs canunderstand easily the techniques and methods involved in modeling, meshing,loads, constraints, DOFs, Solution methods, getting results, reviewing results,validating results etc. Moreover the beauty of FEA lies in idealizing the real-time
model as an appropriate mathematical model. One can get a reasonable grip onthis subject, with specialized masters degrees.and ofcourse only if you do it fromIITs, NITs and a few Group-1 Colleges/ Universities.
But, we see many B.E Mechanical, Civil Engineers, excelling in the field of CAE.You could also do thisif you have lots of determination to excel in this field, andstudy FEA books and Engineering books as Theory of Plates & Shells, Theory ofElasticity, Theory of Dynamics of Structures, Solid Mechanics, Thermal Stressesand Engineering, Design Optimization techniques, Modeling of Mechanical andStructural Systems etc.
With this course, we are giving a sincere try that gives you a gentle push to reachyour goal of becoming a CAE Engineer. So with this push, we hope that you get
the required acceleration by self-study, thoughts and applications in due course oftime.
The course targets to make an Engineer, know the Basics of various analysesavailable in ANSYS, Modeling and Meshing techniques etc. This course makes youwork on around 18 modeling examples, 13 meshing examples, 45 Structuralproblems, 18Thermal problems, 1design optimization problem and some specialproblems dealt as exams.
The duration would be usually 3- 4 hours a day for 4 to 5 weeks as below.
