Mesh Definition and 224 Threads

These two methods seem like they can be applied to the same situations, and I don't really know when I should apply one over the other. I've only just learned the methods so I'm not very familiar with either though. I'd appreciate any help from general guidelines to specific examples.

Homework Statement Using mesh analysis work out the currents flow through each of the three meshes. From these current values calculate the voltage of node A, and node B with respect to the ground node. Find equivalents of sub circuits A-G, B-G, A-B by applying Thevenin's theory. Then...

hello, while doing the mesh analysis what do you substract to what to get the current that is in the middle of two loops what is the rule to get i1 - i2 or i2 - i1 it depends on what ? thanks in advance for the help :smile:

Hello! I'm trying to find some information about my problem but it doesn't seem very easy. 1 - I have a convex polyhedron defined as the intersection of several half-planes. 2- Now I would like to obtain a triangularization of the polyhedron surface in the best way. Can anyone indicate me...

I'm having trouble finding a suitable material to keep critters from nesting under our solar panels. Galvanized steel mesh oxidizes quickly because being attached to the solar modules, and plastic mesh just isn't strong enough and looks unsightly. I need a steel or metal mesh that will not...

I have a question for the enlightened minds. In physics class we found our debrouille (sp?) wavelength, we found that an average human gives a ridiculously small wavelength. H/p. Now what happens when you do this to an electric current in an exposed wire? (6.626E(-34) m2 kg /...

Homework Statement Find the mesh currents i1, i2 and i3 Homework Equations The Attempt at a Solution I did it this way KVL at i1: 12 + 1i2 + 1i1 - 1I2 + 10 = 0 KVL at i2: 10 + 1i2 - 1i1 + 1i2 + 1i2 - 1i3 = 0 KVL at i3: 1i3 - 1i2 + 1i3 + 12 = 0 I was wondering...

My circuit analysis professor showed us a method of nodal/mesh analysis today that allows us to write the matrix equations for either nodal/mesh analysis just by inspection of the circuit. Is anyone familiar with this method or ever heard of it? The circuits that he used this technique...

I'm quite confused by mesh analysis. I understand that the idea is basically to apply KVL to each mesh. For example, if you have a loop that contains, say, a 3ohm and 2ohm resistor, and that's it, what is the correct KVL equation? Is it simply 0=3I+2I? As another example, check out this...

Hello , I am a 4th year ME ,I have as an Final year project to do a dynamic mesh analysis for the blades of a wind turbine ! unfortunately , i don't know how to start since it is the first time I work with the Dynamic mesh . I practiced ont he Fluent softwares when I took the CFd course, so i...

Homework Statement http://img266.imageshack.us/img266/7097/screenshot01sm8.jpg If I use mesh analysis, can I assume that Ix in the lower right mesh will be my mesh defined current (the only current through that mesh)?

Hi I need to find Vab in the following circuit using Mesh Currents...Ive tried this a million times, I understand the method...but I am definitely doing something wrong. Whould I Simplify the top loop?...if its possible. I've been doing it as 3 loops, but i don't know what to use as a voltage...

Are there any practitioners here who could recommend something along the lines of openfoam for doing moving mesh? I've had no joy in using it but then this probably serves to illustrate my limitations more than anything

So here is what the problem states: Use both nodal analysis and mesh analysis to find Vo in the circuit below. http://synthdriven.com/images/deletable/EEN201-05.jpg My confusion: I'm okay with the nodal analysis, I'm just a bit confused with the mesh analysis... I'm confused as to...

I'm trying to get the equations for this exercise but they're giving me some troubles...I think this could also be done with node voltage,but I've tried with the mesh method.Those are my equations: Eq.1: -13 + 4xI1 + 6xI1 + 2.5xI2 + 7.5xI2=0 Eq. 2: 2.5xI2 + 7.5xI2 + 2xI3 + 8xI3 + 0.8vo=0...

This is a question from a review for our midterm coming up soon. I don't understand what I am doing wrong and need some guidance. It would be rather tedious for you (the reader) to view an ASCII circuit, so here is a http://static.flickr.com/46/118451767_63645eb724_b.jpg"of my work...

Hi Guys! well! i have made my all efforts in solving this circuit please help me. WHat technique should i use? Super mesh? or what? Plz help me

I need help with the following mesh problem. Doing the source conversion screws me up. I really need to get this problem correct and would like to check my answer with somebody who is more competant than myself at mesh analysis. Please help asap Thanks in advance

AN ADVICE: "If you are not familiarized with mesh generation, don't keep on reading, you will not understand nothing and I will not make you to waste your time." Sorry if it is not the appropiate forum for posting my problem. I'm currently programming an elliptic mesh generator in Matlab...
