Test electrostatic solution: meshing and accuracy

In this article (the sixth in the online course Electric and magnetic field calculations with finite-element methods), we’ll make several calculations to understand the effect of element size on solution accuracy. To expand our technique toolbox, we’ll automate steps in the analysis procedure.

We’ll continue with the solution discussed in the previous two articles. The best way [...]

Test electrostatic solution: calculating and analyzing fields

In this fifth section of the online course Electric and magnetic field calculations with finite-element methods, we’ll use the mesh file discussed in the previous section to build a field solution. To get started, run EStat from the TriComp program launcher. Click the “1″ tool and choose the Mesh file COAXIALCYLINDERS.MOU. The program determines the defined [...]

To mesh or not to mesh

The process of mesh generation represents a significant fraction of the effort in building a finite-element solution. Many people have an aversion to the very idea of mesh generation, possibly from encountering quirky and unreliable old programs. Some producers of finite-element software may capitalize on this sentiment by claiming that their program does not require meshes. [...]

Test electrostatic solution: building the mesh

This article is the forth in the online course, Electric and magnetic field calculations with finite-element methods. In the previous article, we followed a prepared example without going into the detail of how the input files were prepared and how the mesh parameters were chosen. Now, we’re ready to build an example from scratch and learn [...]

First 2D electrostatic solution

This article is the third in the online course, Electric and magnetic field calculations with finite-element methods. In this section, we’ll run through the steps of a solution and analysis of a 2D electrostatic problem without going into detail. The goal is a quick demo of the capabilities of EStat. Subsequent articles will cover details of [...]
