This webinar on Simcenter Femap discusses how to idealize solid geometry into efficient numerical models that are quick to run and can generate accurate results.

Anyone can take an object, mesh it, apply some boundary conditions and, with a click-of-a-mouse, generate some colors. However, it’s a bit more challenging to transform a mishmash of color into a verified and accurate simulation.

Speed is important; achieving an answer that you can trust often means running the same model dozens of times. So, we will cover how to take a chunk of junk, mesh the impossible, hex what is hexable and tet the rest. Then we’ll discuss element quality and how to make it run quickly.

 Topics we cover:

  • Difficult Geometry is Real Geometry: Geometry Cleanup (removing blends), Mesh Preparation
  • Why is Hexing so Difficult and Why Should We Care – A Nod to Those that just Tet Everything
  • Being Clever with your Geometry Battles – Let’s Step Back and Think about the Analysis Objective
  • Why Do So Many Simulation Engineers Think That Mesh Refinement Makes An Accurate Analysis?
  • Easy Ways to Check Your Mesh Resolution (Normal Modes Analysis) to Determine If It is Good Enough
  • Don’t Fall In Love with 10-Node Tets and If You Do, Use the Iterative Solver
  • Lastly, If It Looks Good, Most Likely It Is Good

What we don't cover:

  • Bias Toward Any One FEA Software Program – This Seminar is for Any and All Simulation Engineers
  • That FEA is for Everybody, as one Chief Engineer told me “many engineers think that they might enjoy simulation…” So, we are not going to sugar coat anything. Getting the “right” answer is hard work and no FEA program created on this wonderful green Earth is going to ensure that you will get the right answer – only through your hard thinking is the way forward.
