[Getdp] FW: how to get coordinates of potential vector

Thnaks,

Actually I am doing an axi-symmetric computation. The problem is that
the result of the magnetic energy is not correct using the integral (r
AJ) over the conductor whereas integrating the magnetic energy density
works over the entire domain.

I am going to post more details to explain the problem.

Best,

Frederic-

Hi Frederic,

the function X[] accepts no arguments. It just delivers the actual x-coordinate
during the integration.
But GetDP can handle axi-symmetry directly by applying VolAxi and/or SurAxi as 
Jacobian-type. See for example:
https://geuz.org/trac/getdp/wiki/TorusCurrent
or
https://geuz.org/trac/getdp/wiki/RadiativeHeatTransfer

Cheers
Michael

Hi,

I am trying to compute the magnetic energy using the axi-symmetry of the
problem and the following formula: integralOverConductor of (pi*X*A*J),
where X is the coordinate of A and the radius in the axi-symmetric
problem (Y corresponds to the axis of symmetry), A potential vector, and
J the density of current in the conductor. I need to get the coordinate
X of A. Here is what I tried to do:

 {Name EMagAJ; Value{Integral {[(2.*Pi/2.)*X[{A}]*{A}*{Je}]; In
magneticSolutionDomain; Jacobian jacobianVolumeRegion; Integration
basicIntegration;}}}

which gives the following error message:

Error   : './methodForMagnetostaticProblem.pro', line 190 : Wrong number
of arguments for Function 'X' (1 instead of 0)


Best,

Frederic
