    Hello,
    I am using an electromagnetic simulation software called Ansys Maxwell for simulations of magnetic field of a permanent magnet. In that I have drawn a cylinder, assigned the material AlNiCo5 to it. I have assigned a regoin to this geometry and then analysed this solution. But it still gave me this error:
    Solenoid3D (C:/Documents and Settings/FABLAB/My Documents/Ansoft/)
    Maxwell3DDesign1 (Magnetostatic)

    [error] Process 'hnl3d' terminated abnormally. It may have run out of memory or could have been killed by the user. (3:19:06 PM Jul 09, 2013)
    [error] Simulation completed with execution error on server: Local Machine. (3:19:07 PM Jul 09, 2013)

    does any one have any idea why this happens?
    I would really appreciate your help.

    It would appear that you ran out of memory (And I am not being smart, here.)
    As you run successive passes, the information generated increases and can increase beyond your systems resources.

    I have tried reducing the number of passes but still it gives the same error. My PC has 3GB RAM which i think should be sufficient generally.

    Generally, yes. But what you're running can be a memory hog. A complex series can run up 15 gigs, easily.
    I have not used quite the same thing, but something similar. An average first pass was nearly 5 gigs. Second pass upped it to 7 gigs; third pass, 11 gigs and so on.
    I only ran these simulations on University equipment.
    If you have access to a machine with heavy memory- You might try grabbing an external harddrive and trying it out on that.

    This is only a post on an error given by software and I could be quite wrong and when it comes to troubleshooting software- it's best to just start out already bald.
    But if you've got only 3 gigs of RAM, I'd consider it a safe bet that you may need more than that depending on what sims you're running (Also take into account that the program will not get the full allotment of RAM you have in any case.)

    Hello everyone,

    i want to to calculate my B field with respect to the x coordinate and Ampere along a non-model line within my model, which contains of two solenoids.
    Using a ParametricSetup to explore the inductances for several position tolerances, i now like to see how my B- field changes in the different relative positions by
    changing the Ampere value along the non-model line.
    Any other values stay constant.

    Does anyone know, if that is possible using the field calculator?
