This past week I’ve been experimenting with solving magnetic field problems. Here is my first result. Two wires are in the center of the figure with current flowing in opposite directions. The solution variable is the magnetic vector potential, A, and is shown in the color gradient. The arrows are the magnetic field, B, which is post processed from the solution. In turns out this post processing is similar to finding the vector impedance field used in noise analysis.

Mulling over the importance of 3d simulation.  I’m by no means a meshing expert.  Looking for third party tools to create tetrahedral meshes.  As of now gmsh seems to look promising.

What are the most important features in a semiconductor device simulation software?

Is it accuracy, number of models, advanced models, 3d? What about ease of use, scripting capability, extensibility? Anything to be said for licensing models or price?
