Which table card image to use for multiplication with a constant

IRA_EM_21281

Hello All,

 

 I have RLOAD1 cards defined via the TABLED1 however I would like to multiply this table by a constant before it is called by  the RLOAD1 card.

 

Is this possible?

you can use the DLOAD Scale Factor (S) to do that. Or you can increase your SPCD/DAREA, so that it will multiply your table values.

I dont think the DLOAD S factor will work because my TABLED1 has an x and  y value, each which needs to be multiplied by a different constant.

 

Ie, the columns of X times constant A and column of Y times constant B.

 

I am probably better just multiplying in the constants in excel and then import table as my last option.

Adriano_Koga

usually what people do is to have the TABLED1 as a unit table, and then the SPCD gives the amplitude (multiplier for the Y column of the table).

Or vice-versa.

 

I don't get it why the Scale Factor in DLOAD won't work for your case. The DLOAD Si constants can be adjusted for each of your RLOAD1s separetely.

And the only thing they change is the Amplitude (y-axis) of your table, not the frequency (x-axis)

 

It should work by adding these multipliers 'Si' inside DLOAD

ok, then I had misunderstood you.

 

Si constants is what I need to adjust the y columns.

 

For the x column (which are in rpm) I need to manually convert this to frequency in excel and then import unless there is another option to change the x column?

 

Adriano_Koga

correct. You will need to manually adjust the X values.
