WKB model in nested grids ERROR [gino rivano]

Hi all,

I’m trying to run a croco simulation with a nested configuration using the WKB
wave model, but I can’t run both simultaneous (AGRIF and WKB model). The
simulation compile perfectly.
The problem seems to start in the child wave computation:

 Maximum grid stiffness ratios:   rx0 =0.2286000333  rx1 =  3.0506158540

 GET_INITIAL -- Processing data for time =   6027.     record =   1
 GET_BULK   -- Read fields for bulk formula   for time =    6027.    
 GET_BULK   -- Read fields for bulk formula   for time =    6027.    

 WKB: started child wave computation.

 At line 362 of file AGRIF_FILES/modbcfunction.F90
 Fortran runtime error: Attempting to allocate already allocated variable 
 'parray2'
 Program aborted. Backtrace:

 At line 362 of file AGRIF_FILES/modbcfunction.F90

 'parray2'

attached file contain simulation details

I’ll really appreciate your help. Thanks in advance,
Gino
