Varying load describtion???

Varying load describtion???

(OP)
Hi Dude,

Is there any one who have never seen anything like that???

That give me a sinusoidal load using:
TIME,360
and
DELTIM,6

But How this matrix can be explained????

Many thanks to give me pieces of information or to help me locating it in the help file.

RE: Varying load describtion???

Hi,
I fear your question can not be answered: this is an internal ANSYS notation for building equations. The fact that it writes coefficients into a table has nothing to do with how YOU input values into a "meaningful" table (I mean, meaningful for you).
For example, I use a rotodynamics program that uses a similar manner to store equations of time-varying excitation functions: one coefficient is, for example, a code by which the program chooses the "type" of the function (0=constant, 1=linear, 2=polynomial, 3=sinusoidal, 4=exponential, etc...), other coefficients depend upon the type, and so on "in chain", so the resulting matrix is absolutely unreadable by the user (well, in this particular case it is, if you use the manual and a LOT of time and patience; but why would you do that ???).

Regards
