Getting started with Explicit FEA


Getting started with Explicit FEA

Jump start your use of Explicit FEA.

Our getting started series is intended to help you hit the ground running. This getting started with Explicit FEA course:

Getting Started with FEA
  • is intended to be the first resources you should use to grow your knowledge of the explicit analysis process;
  • will help you learn the principles of the explicit solution process and how it differs from an implicit process;
  • introduce you to some of the terminology and jargon that you will hear from users of the Explicit method;
  • give you an awareness of the advantages and disadvantages of the explicit process;
  • provide you with some basics checks you should perform to gain confidence in the results produced by the explicit process;
  • share tips on where to go next to further develop your expertise in this area.

This course is relevant to newcomers and experienced analysts who want to develop their skills with Explicit solvers. The course features examples from well known Explicit code vendors however the methods and techniques discussed in the course are embedded within all major Explicit solvers.
