The Ansys Innovation Space website recently experienced a database corruption issue. While service has been restored there appears to have been some data loss from November 13. We are still investigating and apologize for any issues our users may have as a result.
Cornell SimCafe Structures
This SimCafe Structures Learning Track was developed by Dr. Rajesh Bhaskaran at Cornell University in partnership with Ansys. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. The following courses show how to solve structural problems using Ansys Mechanical. These tutorial-based courses follow the same high-level steps; starting with pre-analysis and ending with verification and validation. The successful completion of these simulation courses will provide a thorough understanding of how to set up a Structural simulation using Ansys Mechanical.
