Hi,
Is there an overlapping section in the MPI part ?
Otherwise, please check :
- declaration type of all the variables (consistency
Hi,
Is there an overlapping section in the MPI part ?
Otherwise, please check :
- declaration type of all the variables (consistency)
- correct initialization of the array "wave" (to zero)
- maybe use temporary variables like
real size1,size2,factor
size1 = dx+dy
size2 = dhx+dhy
factor = dt*size
