Large Scale Modeling Techniques
Finite Element models continue to grow in size and analyzing a large number of components in an assembly is becoming easy. Multiple CPU machines are common-place and, with the ability to mesh…
Modeling Bolted Joints & Understanding Load Transfer
Understanding how structural parts interact and transfer load through mechanically fastened joints has long been a critical aspect of design. Even with the development of integrally machined parts, additive manufacturing, friction…
Performing Finite Element Analysis Outside the Box
An FEA consulting customer recently asked if CAE Associates could perform a structural analysis of the response of human bone that has undergone a transplant procedure. Before giving a definitive answer, we quickly went through…
Modal Submodeling
Submodeling is an important technique in finite element analyses that allows us to get a more accurate answer in a local region of a larger model. Often computational and time limitations prevent us from…
Accelerating Simulation Run Time with GPUs
As engineers, we're constantly faced with technical problems that require us to push the limits of what was previously thought to be possible. The continued development of simulation tools like FEA…
High Performance Computing for FEA and CFD Analysis
A common question our FEA and CFD analysis customers ask us is “What hardware should I buy?” Purchasing a new high-performance computing (HPC) capable machine can be an intimidating process and lead to paralysis…
Fluid-Structure Interaction
Studying the interaction between fluids and structures is becoming increasingly important in today’s design world. The reasons for this are simple. How can you fully understand what’s happening in a…
Finite Element Analysis workflow
Below I will give you the FEA workflow with short descriptions what to do in each step. FEA Workflow 1: Geometry This is the part that is the most obvious.…
Dealing With Incompressibility
If you have ever tried to model the structural behavior of an elastomer using finite element analysis as part of your FEA consulting projects, you may have experienced the painful process of…
5 steps of FEA results verification
Whatever we design life will verify it at the end… but I would rather know if my design has a fighting chance before any major collapse occurs! This is why…
