hi
how i can model a plate with the Sin(pi*x/a)*Sin(pi*y/b) load function.?

1. First you should define the function as follows (the function name is "current" that you can change it according to your case)
! The equation is: "1000*((sin(100*{PI}*{TIME})^2)^(0.5))"
*DEL,current
*DEL,_FNCNAME
*DEL,_FNCMTID
*DEL,_FNCCSYS
*SET,_FNCNAME,'current'
*SET,_FNCCSYS,0
*DIM,%_FNCNAME%,TABLE,6,12,3,,,,%_FNCCSYS%
! Begin of equation: {TIME}
*SET,%_FNCNAME%(0,0,1), 0.0, -999
*SET,%_FNCNAME%(2,0,1), 0.0
*SET,%_FNCNAME%(3,0,1), 0.0
*SET,%_FNCNAME%(4,0,1), 0.0
*SET,%_FNCNAME%(5,0,1), 0.0
*SET,%_FNCNAME%(6,0,1), 0.0
*SET,%_FNCNAME%(0,1,1), 1.0, 99, 0, 1, 1, 0, 0
*SET,%_FNCNAME%(0,2,1), 0

*SET,%_FNCNAME%(0,10,1), 0
*SET,%_FNCNAME%(0,11,1), 0
*SET,%_FNCNAME%(0,12,1), 0
! End of equation: {TIME}

2. Then you should apply the load on nodes:
FLST,2,1,1,ORDE,1
FITEM,2,429
/GO
F,P51X,AMPS,%current%
! %current% is in fact the sinusoidal load that defined as a table
