I have tried it but i cannot plot 1D. The program told me, Unknown function or operator.

- Name: comp1.intop1

- Plot: glob1 (Global)

I dont know how to solve this problem.

Pls let me know what i wrong to do it.

I used comsol version 5.2

thank you ]]>

I would suggest that you contact your COMSOL support team with your questions so they can help you.

I want to see the effect of different winding materials on generator’s performance.

How many multi turn coils would be required? What changes i would need to make to calculate efficiency of generator ?

In this particular example, we are demonstrating how to compute the induced voltage in domains using the line integral of the electric field.

Alternatively, you could apply a Multi-Turn Coil feature to these domains and automatically compute the induced voltage in the windings. If you apply the Multi-Turn Coil feature, the conductivity value will be specified in the settings window of the Multi-Turn Coil feature.

Here is another tutorial model, which uses the Multi-Turn Coil feature: http://www.comsol.com/model/mutual-inductance-and-induced-currents-in-a-multi-turn-coil-12687

]]>I am new to comsol. I was wondering if this model includes the stator winding also as in the materials list I only see air and soft iron. I do not see copper anywhere which is commonly used as winding material.

please let me know how this is included. ]]>

I was reading the model documentation pdf , and took a quick look at the model .mph file . I would say it was really interesting, However I am confused of not adding the Moving Mesh (ALE) physics ! does that effect the results ? since the mesh does not moving ! only the spatial coordinates moves !

I tried to add the moving mesh by my self , but i got stuck with x,y,z and X,Y,Z variables which seems there is a variable looping which COMSOL cant take it ! and when using the Material coordinates X,Y,Z , the mesh also doesn’t move !!

any explanation ! ?

Best Regards ;

]]>if so which part of COMSOL i have to download and one more thing i have to get the transfer function of the dynamos can it possible to get through this software ]]>

Please check out the model in our Model Gallery: http://www.comsol.com/showroom/gallery/2122/

If you log into your COMSOL Access account you can get the documentation for this model, which explains how to simulate it in COMSOL. (If you don’t have an Access account, you can create one for free following the on-screen instructions).

]]>I have some confusion about this model .One thing that confused me is the coil in this model. In the model there is nothing that mention about the coil and there is no boundary condition for the coil too.

Please let know how coil domain is used in this model.

thank you ]]>
