! Postprocessor plot of acoustic pressure
! along the path between the nodes N_RES1, N_RES2 at the frequency FRES
! N_RES1, N_RES2, FRES - should be determined earlier
/POST1
/COLOR,CURVE,WHIT,1,6 ! graph color -- white (black after invertion)
/COLOR,GRID,WHIT, ! grid color -- white (black after invertion)
/PLOPTS,TITLE,OFF ! no graph title
/PLOPT,FRAME,OFF ! no frame
/AXLAB,X,Y   ! label for X-axis
/AXLAB,Y,Re PRES  ! label for Y-axis
/XRANG 
/DSCALE,,OFF ! Remove displacement scaling (scale displacements by 0)

! Read results for real part at the frequency FRES
