I'm using the Fields Calculator in Ansys Maxwell 3D and I can find the maximum position at which a fields-quantity occurs (i.e. I get a x, y, z position with respect to the global co-ordinate system). Is there a way in which I can convert this x,y,z vector to a point in the fields calculator that does not require manually creating a point at position (x,y,z)? 

The reason I would like to do this is because the fields calculator allows me to find the maximum field quantity (e.g. B-Field) at a certain point, but it only gives me the magnitude, however I require the x,y,z vectors.

hi mega_kai2, how did you calculate B field, I need to calculate but I can't.

Thanks.

mega_kai2: Use the 'ScalarX', 'ScalarY', and 'ScalarZ' each separately on the max value position to create three calculator expressions for the X, Y, and Z values. Then you can create a new point with these three new calculator expressions.

 

okara: B = u_0*H; Multiply H by mu zero (the permeability of free space, 4*pi*10^-7) in the Field Calculator to compute B. It is pre-programmed under the 'constants' button in the Field Calculator.

Hi Peter Serano,

I want to find the magnetic field (B_vector) around the magnet along with the line. Actually I want to generate this type of graph from ANSYS Maxell. Last couple of months I am trying to find it. Could you please help me?

The first step is to draw a line or spline or some kind of 1D line object that is located in the position where you want to plot the field value. After the geometry has been created, you can right click on 'Results' and then select 'Plot Field Data > Rectangular Plot'. Then in the plot options, select the quantity of interest and select the line object under the 'Geometry' option.

Hi Peter,

I way you said it gives Mag_B vs distance graph. But I need Vector_B vs distance graph. I have found a graph in 3D transient but is vector_B vs time graph. Can you send me any tutorial regarding my issue?

Thank you

@Raju07 - "Vector_B" has a magnitude and phase (real/imag) components. You can only plot scalar values on a plot - so you'll need to use the re(), im(), mag(), or ang() functions to plot your data. The plot that you uploaded is not a vector - it is a 2D plot of scalar values...

[okara]

@Raju07 you first select vector which one you want in calculator and select scalar bx or bz or by and select geometry and integral so your formula is ready. analyse and get results and plot. 

[okara]

@Raju07 your formula will be like this.  (Line(Polyline1), ScalarY(B_Vector))

Thank You, Okara.

Hi

I saw it works for Cartesian coordinates. But how can I plot the radial B or Tangential B (Cylindrical Coordinates)?

There is an option to convert to cylindrical coordinate system, but how to extract r, theta and z component from that vector?

 

Thanks

Raju07 okara Please could you boh guide me how to get a vector plot for B in the B vs distance rectangular plot.
