	Procedure BIOVOL 
        -----------------

             CHP1 = BIOVOL GEO1 GEO2 CHP2 FLOT1 


	Description :
        ------------

        Calculation of the magnetic field by means of BIOT ET SAVART,
        by integration on elements of any form.

        Contents :
        ----------
 
           GEO1   inductor mesh 
           GEO2   mesh on which the field is calculated
           CHP2   chpoint of the densities of electric current on GEO1
                  (JX JY JZ) can be obtained by calling on COUR3D

        output data :

           CHP1   chpoint of induction on GEO2  (BX BY BZ)
