Hi Mike,

To resume the problem, what I want to do is to load a table on ANSYS
with my HGEN time dependent values (Calculated with another code) and
apply them as a loads. Since I calculated those values with a very fine
mesh It could be interesting to use a broader time stepping for my
ANSYS solution (although my table will have much more information) in
order to reduce my computational time.
