I want to calculate the ultimate strength of ship bottom panel. I need to impose initial imperfection, which has a complex shape (overall buckling mode+thin horse mode). I calculated deflection values at the panel but I could not impose these values to the FE model.

Dear Hamid,
Yes, It has been solved. I have imposed initial deflectios by APDL. You may generate a table containing initial deflection values or read the values from an external ".csv" file. Than you can write a script similar to the below one. INITTP15 is a table containing initial imperfection values.
*DO,I,0,50,1
*DO,J,0,50,1
NSEL,S,LOC,Z,0,0
NSEL,R,LOC,Y,(5*B-I*B/10),(5*B-I*B/10)
NSEL,R,LOC,X,(J*A/50),(J*A/50)
D,ALL,UZ,INITTP15(I+1,J+1)
