EMField-funcEmField

funcEmField

Defines an EM field using a block to describe the characteristics of the EM field. funcEmField requires use of a code block.

funcEmField Block Parameters

STFunc (block)

The function that sets the value for a specific field component. The name of the block determines which component. E0,E1,E2 sets the x,y and z components of the electric field and B0,B1,B2 does the same for the magnetic field. See STFunc Block.

Example funcEmField Block

<EmField myExternalField>
  kind = funcEmField
  <STFunc E0>
    kind = expression
    expression = EX_1 * cos(K_PE * x) * H( DRIVE_TIME - t )
  </STFunc>
</EmField>
