Thanks gerbi,

I already did the band object. I have no idea where it goes wrong with my simulation. I give it another try. Many thanks for you help.
 
Engineering news on Phys.org
Double check it. Verify if the band object is big enough to contain all objects during motion.
 
Eddy,

Just to be clear, the band should enclose all the moving objects, but none of the stationary objects. Also, since models with motion use the transient solver, you may (probably will) need mesh operations to get a good mesh for good results (the adaptive mesher only works for static models). What type of phenomena are you trying to simulate? Is the model 2D or 3D?
 
Hi pkelecy,

Thanks for your advice. I am simulating a linear actuator in vertical motion. This is a 3D model simulation. As for mesh, I have set the mesh operation as suggested. But, still no-go for my simulation. Need to figure out what the problem.

Thanks,
Eddy
 
What is the error code ?
 
Hi guys!

I have tried to do the analysis of Magnetic Rotational Actuator, described step by step in Maxwell's example files. I am using Maxwell 14.
I have completed the whole process, but when i try to do the simulation i get:

[error] Failed to load 'Matrix1' solution. (12:24:29 AM Sep 09, 2013)
[error] Failed to evaluate calculation 'Matrix1.L(Current_1,Current_1)'. (12:24:29 AM Sep 09, 2013)
[info] A variation (ang='15deg') has been requested on machine Local Machine (12:24:29 AM Sep 09, 2013)

I first thought that I made the mistake in the process, however, i noticed that there is a file in maxwell's examples that already had this model done by ansoft, and all the parameters were identical to the file i made. I tried to run a solution but i got the same errors. Failed to load matrix1 solution.

Can anybody please help me with this error? I am quite new to maxwell.
 
I tried the same file on the PC with new version of maxwell, and it was working just fine.
So, i guess it might have been a bug in the software.

On the different note, I wish maxwell would give some more info on the errors it gives out, not just, "failed to evaluate calculation". That might actually be useful, but then again,they might not be able to charge an arm and a leg for 3 hours seminar. Their training prices are nuts...
 
Hello,

I have a question about Maxwell 2D Transient. If you choose the Core Loss, Maxwell Core Loss calculated via:

Kh is the hysteresis core loss coefficient,
Kc is the eddy-current core loss coefficient, and
Ke is the excess core loss coefficient.

Obviously then calculated losses due to eddy currents (Kc).

If I am under the Set Eddy Effects, select the same part where I count Core Loss, Shall I then get double losses due to eddy currents

Where do you get these info? I don't think Maxwell do any of those Kh, Kc and Ke.

In Material Properties these coefficients can be entered.

Setting: Set Core Loss and mark eg stator, and mark Defined in Material.

According to this, Maxwell Core Loss calculated as determined coefficients.
 
I see it. This is for steel. I guess you need to Set Eddy Effects in order to have the correct current distribution, but I am not sure.
 
Hi guys,

I am new to here. I am trying to use transient solver for a inductive power transfer simulation. The simulation time and save field was set from 0 to 0.2 ms. The simulation was finished, however only data between 0-0.104 s were saved, the data between 0.105-0.2 ms were shown n/a. Does anyone what might be the reason for this situation? Thanks!

Shuo
 
I think that simulation is not converged. Check the number of finite elements and settings of Solver
 
Thanks, There are 69873 meshes. What can I do with the setting of Solver?
 
hye all

im a new,, i have a some problem in ansoft maxwell 3d,,

1) what mean about this error when I am analyze the program

Maxwell3DDesign1 (Magnetostatic)
[error] There are multiple disconnected solution domains. This is not allowed in magnetostatics. (11:17:49 PM Nov 14, 2013)
[error] Simulation completed with execution error on server: Local Machine. (11:17:49 PM Nov 14, 2013)

2) i need to use the permanent magnet in my project,, so to assign material what is the name for the permanent magnet i need to select? then, how to assign boundary, excitation, parameter for this material,,

hope anybody can help me to solve my problem,, :( tq all

im also attach my project picture

Hello

"Multiple disconnected domains" means that you need to create a region (Draw->Region). This operation creates a space where your experiment will take place.
You need to assign a permeant magnet.. well.. there are multiple materials. This is up to you to select one of them depending on design (yes, NdFe30 is one of them).
The only thing you need to select for permeant magnet is polarisation of magnet (after you select a material go into its properties - you'll find there XYZ components of magnitute that describes polarisation of magnet).
 
ok tq so much bro gerbi,, now i have solve the problem,, tq
 
hello all

i still have a new error about 3d coil,, i don't know how to setup excitation/boundary for current or else,, so what need i do for this part ( 3d coil )

this is my error when I am try to setup excitation

Maxwell3DDesign1 (Magnetostatic)
[error] Verify conduction path 'Path1': For any conduction path that has current density excitation(s) specified, current density terminal(s) should also be specified and vice versa. (11:44:05 PM Nov 17, 2013)

pls help me,, tq all :)
 
hi i need to design a transformer with carbon nano tube wires instead of copper wires..can anyone say how can i do using ansoft maxwell
 
ansoft maxwell 2d

hello,
I am designing a switched reluctance motor with double layered winding using ansoft maxwell 2d.Can anyone help me with connecting an isolated supply in between each phase windings in the circuit editor part.
Thanks.
 
Help Required

I want to design a linear generator with square shape;
Based on previous work i have found that finite element analysis of tubular (circular shape) is done in cylindrical (2D RZ plane). But when the shape is square in what coordinate system we can do finite element analysis. Please help me regarding this.
 
[Error] Failed to evaluate calculatoin Matrix1.L(...)

Hey guys,
by solving a parametricSetup, the error
[error] Failed to evaluate calculation 'Matrix1.L(Current_0,Current_0)'
appears in the Message Manager.

I am using Maxwell 16 and simulating a model with two flat coils.

Using Maxwell on a different computer doesn't solve my problem. Though, the licenses are being distributed by a central server.

The problem occures whenever i copy a model in the Project Manager and add it to the same and/or different opened project to use the same settings but alter the number of turns of the flat coils.

On my way to find the error, i discovered that the problem occures whenever i run the original simulation to check the first parameter steps and use clean stop. After the completed abortion, the copy of that model always happens to have the Error mentioned above.

By a non-aborted model, the problem hasnt accured, so far!

Since i am going to use many altered copies of one orginal one, i want to reinsure the problem will not appear troughout all the copies.

Does anyone has had the same problem and can confirm my suggested error´s source?

I appreciate your help.
 
Hi,

I don`t know if I`m in the right section to explain my problem..
First of all, I would like to visualize eddy currents. So I create 2 solids (coil and solid looks like a `U` compose od ferrite) in solidwoks and I imported them in MAXWELL 3D.

When I decided to apply a current on a surface in the coil, I had an error when I created a surface... The operation is in the tutorial is : Modeler»Surface»section..

I attached 2 pictures to show my problem..

Thank`s

Hi everyone,
I want to plot cos waveform in maxwell. can anyone give me the formula. Thanks
 
sorry, I am new here, , how to display the value of the flux Intensity of each point from a position to another position?

if you want to plot it; just draw a line in air gap and follow

thanks , but after I tried it, the value (mag_B Tesla) was too high , there are any another setting to do to get precision value??

based on my knowledge there is another method; that is using calculator but for getting this you go through maxwell guide that has complete how to use calculator explanation

I want to see how my B field changes with changing Ampere with respect to the coordinate.
Therefore i use an rectangular plot along a non-model line to see the change of my B field.
Is there a way to calculate my B field with respect to my coordinate and several Ampere values?
Since i don't have the time to set an ParametricSetup up for all Ampere combinations with all the other changing geometrical components, i am glad for any hint.
