brcast()

subroutine brcast

(

integer, intent(in)

lvol

)

Broadcasts Beltrami fields, profiles, . . .

broadcasting

• The construction of the Beltrami fields is distributed on separate cpus.
• All "local" information needs to be broadcast so that the "global" force vector,

  \begin{eqnarray} {\bf F}_i \equiv [[p+B^2/2]]_i = (p+B^2/2)_{v,i} - (p+B^2/2)_{v-1,i} \end{eqnarray}

  can be constructed, and so that restart and output files can be saved to file.

Parameters

[in]

lvol

index of nested volume
