Solving Navier-Stokes by Finite Element

Submitted by Student123 on Sun, 05/15/2011 - 17:18

Hello

I want to solve a system of partial differential equations (Navier-Stokes with continuity and momentum equations in one-dimension) using a finite element routine. I have several questions:

1. How to couple the two equations (continuity and momentum) into a single system with a single solution.

2. Apart from time, I have two unknowns: volumetric flow rate (Q) and pressure (p). Should I consider these as two degrees of freedom on each node in the domain.

sweep mesh of a dome in ANSYS

Submitted by tunl on Sat, 05/14/2011 - 01:20

I am dealing with a partial sphere dome in ANSYS, I created the volume by extruding half of an arch area along the axis at the dome center. I am using SOLID65 elements. The problem I am facing now is how to properly sweep mesh the whole volume ( actually, there are four 90 degree partial sphere together after the extrude of the area), because if I simply sweep the volume, the elements around the top center of the sphere will cause element shape warning in the static analysis.

Dose anyone have any idea about how to deal with the mesh around the center?

Instrumented Indentation, It's More Than Hardness

As the validity of Instrumented Indentation continues to expand throughout all materials research, many throughout the community are still unclear as to what exactly can be achieved. Although advances in technology will continue to grow the list of capabilities of Instrumented Indentation, we will review a list of what can be expected as of now. But first lets quickly review how Instrumented Indentation works.
