5 Use Cases for Abaqus CAE in Multiphysics Simulations

EmailFacebookLinkedInTwitterShare

Simulations that show the effects of multiple environmental factors offer essential insights to product developers. From the early days of simulation, incorporating multiphysics simulations has been a core need for engineers and designers alike. Real-world product performance is often dynamic and nonlinear in nature, with scenarios playing out in unexpected or hard-to-predict ways—at least without the aid of advanced simulation programs. Static, dynamic, thermal, electrical, durability, and other stressors will have compounding effects that are more complex than 1 + […]

4 Applications for FEA Simulation in Life Sciences

EmailFacebookLinkedInTwitterShare

FEA simulations can be applied to life science to improve product design and advance medical research. Computer-aided engineering (CAE) has improved design and development processes in industries as diverse as aerospace, green energy, and high-tech devices. However, nowhere does CAE have a more direct impact on quality of life than in the life sciences. During my time as a graduate student, postdoctoral researcher, and CAE simulation engineer, I have had numerous opportunities to use finite element analysis (FEA) along with […]

Abaqus Convergence Problems: What Do I Do About Negative Eigenvalues?

EmailFacebookLinkedInTwitterShare

My simulation is not solving efficiently and diverges. I have negative eigenvalues in my message file, what does this mean? To answer this question, let us take a brief look at the finite element method. Your model is being turned into a representative stiffness that we call a stiffness matrix. These are the same matrices you studied a long time ago in math class. However, they have the possibility of having millions of entries as your model becomes large! The […]

How Do You Get Your FEA Units Consistent?

EmailFacebookLinkedInTwitterShare

Unit choice and consistency is a topic that’s very near to a lot of engineers’ hearts.  We tend to have strong opinions about other people’s differing opinions on it, and when we find unit mistakes, they can be some of the most spectacular screw-ups in engineering history.  So how do we avoid embarrassing unit mismatches and surprise dimensional analysis?  With handy reference and clever calculator tools: Getting Consistent Units: A Helpful Table Abaqus has no built-in system of units. Therefore, […]

What’s the Difference Between C3D10 and C3D10HS Elements?

EmailFacebookLinkedInTwitterShare

And When Do You Use One Over the Other? The C3D10 and C3D10HS are both 10 node tetrahedral elements in Abaqus with quadratic interpolation of displacement, otherwise colloquially referred to as “2nd order tets”. While the C3D10 is the standard or “vanilla” 2nd order tet element, C3D10HS is marketed as a 2nd order tet element with improved surface stress visualization. To understand how and why C3D10HS is different from C3D10, we need to quickly review how stress is calculated using […]
