SIMULATION-DRIVEN DESIGN

As we have already examined in our earlier post “Empowering design engineers to perform their own simulation” about the practicality and functionality of Altair SimSolid, we are now going to talk about the accuracy of SimSolid by employing NAFEMS Benchmarking tests.

Ian Symington, Engineering analysis and Simulation expert of NAFEMS, investigated the accuracy of Altair SimSolid through a series of 8 analysis benchmarks, and has thus proven SimSolid to be a very reliable tool. Here are 2 of the aforementioned 8 benchmark tests that have been listed below.

Benchmark 1:

Cantilever Under End Load:

The cantilever has a square cross section and is loaded with a distributed force acting on the end face. The target solution can be obtained from an engineering handbook or using general purpose FEA code. Both the peak deflection and bending stress are defined as the targets of this benchmark.

The target displacement and stress results produced by SimSolid are shown in the table below.

SimSolid – Direction stress acting in a direction parallel to the length of the beam (shown below)

SimSolid – Deformation in the direction of the applied load (shown below)

Benchmark 2:

Pressure Component

The cantilever has a square cross section and is loaded with a distributed force acting on the end face. The target solution can be obtained from an engineering handbook or using general purpose FEA code. Both the peak deflection and bending stress are defined as the targets of this benchmark.

The pipeline is to be analyzed in order to determine if the component is appropriately designed to withstand a 100MPa pressure load. The goal of the benchmark is to predict the peak Von Mises stress in the component.

SimSolid - Contours showing Von Mises Stress is shown below:

The target solution is shown in above image with the target peak stress at 530MPa. The peak Von Mises stress predicted by SimSolid correlates to within 1% of the target solution. The benchmark results produced by SimSolid can be seen in the table below.
