[SM v3.5a] Rotation constraints in structural module. With complements

Ivar KJELBERG, CSEM sa
Last updated: April 30, 2010

3 reviews

There are different boundary constraints in COMSOL structural, but in 2D/3D structural (smpn, smsld ...) there are no angular variables predefined, hence no easy way, as in the Euler beam modules,...

[SM 3.5a] 3D Euler Beam Properties Calculations

Ivar KJELBERG, CSEM sa
Last updated: April 30, 2010

5 reviews

3D Euler Beam based FEM models calculate quickly and are very usefull for design otimisation and conctual design phases. In COMSOL, as most FEM codes, 3D Euler Beams require the input of quite...

A MatLAB-based tool for handling Tessellated Free Shape Objects with a Morphing Mesh Procedure

Salvatore Gerbino, University of Molise, IT, Pasquale Franciosa, University of Naples Federico II, IT (pasquale.franciosa@unina.it)
Last updated: February 8, 2010

2 reviews

Description: This is a fully MatLAB-based tool, called ProMESH, allowing to handle tessellated models (in .STL ASCII file format). Open imported tessellated model may be thickened. Geometry shape...

Local Drug Delivery by Infusion through a Multi-hole Sprinkler – 3D Model for a Prototype Bioartificial Pancreas Device

Peter Buchwald, University of Miami
Last updated: December 8, 2009

8 reviews

This is a fully scaled 3D model built to explore the feasibility of localized drug delivery by infusion through a central sprinkler with multiple, non-axial-symmetric holes into a rodent prototype...

[AC/DC V3.5a] Maxwell Stress Tensor "pitfall" example

Ivar KJELBERG, CSEM sa
Last updated: October 8, 2009

8 reviews

The Maxwell Stress Tensor is handy to use to calculate forces on magnets, but the method is very very sensitive to meshing symmetry. This example show the effect of surrounding a square magnet by a...

Various Mode Heat Transfer

AJ Baker, University of Tennessee, Knoxville
Last updated: July 7, 2009

10 reviews

Consider an array of heated tubes submerged in a vessel with fluid flowing past them. Neglecting end effects, the flowfield can be assumed 2-D in planes with normals parallel to the tube axes....

Plane Stress in a Plate With a Hole

AJ Baker, University of Tennessee, Knoxville
Last updated: July 7, 2009

7 reviews

The plane stress analysis of a square plate with a hole at the center subjected to tension is performed using COMSOL Multiphysics. Objectives of this simulation: 1. Evaluate the use of COMSOL...

Vibration of an L-Shaped Membrane

AJ Baker, University of Tennessee, Knoxville
Last updated: July 7, 2009

4 reviews

FEA normal mode vibration analysis of the L-shaped membrane for edge displacement BCs fixed at zero displacement. Objectives of this simulation: 1. Set-up a GWSh eigenmode analysis of...

Flow in a Step-Wall Diffuser

AJ Baker, University of Tennessee, Knoxville
Last updated: July 7, 2009

2 reviews

This example comes from the textbook "The Computational Engineering Sciences" by A.J. Baker. Objectives of this problem: 1. Set-up COMSOL for GWSh solutions for the benchmark Navier-Stokes...
