What software allows visualization of 2D equipotential electric field lines?

Click For Summary
The discussion centers on finding software to visualize equipotential electric field lines in two dimensions, particularly for complex structures like Faraday Cages and line charges. One participant suggests that creating a custom utility in Java could be a beneficial learning experience, emphasizing that all conductors are equipotentials and that line charges can be represented by a series of point charges. However, another participant expresses concern that the complexity of the desired features makes developing such an applet challenging. Overall, the conversation highlights the need for software that can handle both simple and complex electrostatic scenarios.

I'm looking for some software that will allow me look at equipotential electric field lines for various structures in two dimensions. Any thoughts?

I remember I ran into a good looking utility when I was researching antenna design, but now I can't find it...

You just want to see equipotentials for electrostatic situations in two dimensions?

That's so easy! Perhaps you'd learn a lot more writing your own utility. It would be quick to write one in Java...

the component that makes this a little more complicated is that I want to be able to introduce Faraday Cages and line charges, etc... not just point charges.
 
That doesn't make it any more complicated -- all conductors are equipotentials, and line charges can be simulated as a finite set of point charges.

that doesn't increase the likelyhood of me being able to write an applet
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
