HDF5: A Useful Enhancement for MSC Nastran and Patran

Product Marketing — Mon, 29 Oct 2018 21:53:05 +0000

Let’s face it, as FEA engineers we’ve all been in that situation where the finite element model has been prepared, boundary conditions have been checked and the model has been solved, but then it comes time to investigate the results. It’s not unusual on a large project to produce different outputs for different purposes: an ...

Patran Fields

Ken Walker — Fri, 17 Jun 2016 17:00:25 +0000

Fields in Patran are used whenever you need to define variable (non-constant) data. Applications include material properties, element properties, or load variations as a function of time, frequency, or spatial position. Fields are also helpful to map results between dissimilar meshes. Practical uses are briefly described below.

Global Adaptive Meshing In Marc

Product Marketing — Thu, 05 May 2016 03:18:44 +0000

Adaptive meshing is a simulation technique used to automatically remesh parts of a finite element model during the solution phase, based on certain criteria set at the start of the analysis. Adaptive meshing can be broadly classified into two types – global remeshing and local adaptivity. Global adaptive meshing is extremely useful for cases where ...

Piezoelectric Simulations With Marc

Product Marketing — Fri, 08 Apr 2016 04:18:30 +0000

Piezoelectric sensor-actuator technology is often used in high-tech industries like medical, mechanical, automotive engineering and semiconductor markets. Applications of piezo-based ultrasonic sensors range from fuel injectors, flow-rate metering, ultrasonic welding, and high-resolution material testing to medical diagnostics. A piezoelectric finite element analysis involves computation of coupled stress and electric field in certain crystalline materials. In ...

Multi-Scale Simulations With Marc and Digimat

Product Marketing — Thu, 07 Apr 2016 15:30:19 +0000

Composite materials of various types (unidirectional composites, short fiber reinforced plastics, nano-composites, ceramics, etc.) exhibit highly nonlinear, anisotropic, strain-rate and temperature dependent properties in mechanical, thermal and electrical fields. They often exhibit enhanced performance with respect to density as compared to traditional structural materials. However, simulating composite structures is complicated, and usually requires a micro-mechanical, ...
