Plotting function/tabular boundary conditions 2

[BethMech]

Hi,

I am trying to load a gearbox shaft realistically using a function which varies the pressure load with angle (Y) in cylindrical co-ordinates. I have calculated the function required which has the form, Pmag*cos(2{Y}). I have not got the magnitude of force expected so would like to plot my function (which has been read in as a table).

The help section 2.6.15.4 says this can be done using the 'Plot Information' dialogue box. I cannot find this anywhere!

I am using ANSYS ED if that makes any difference. Thanks for your help.

Try plotting the function using:

*VPLOT, ParX, ParY, Y2, Y3,.....

where ParX/Y are your table parameter columns e.g if your table parameter is called "function" and the X and Y values are in columns 1 and 2, respectively use:

*VPLOT,function(1,1),function(1,2)

Don't forget that the table parameter has a zeroth column, column(1,0), in case you need to plot that.

*vplot is your command of choice.

This gives a nice overview on all the plotting options.

Thanks both for the replies.

I have had a go with VPLOT but am unable to tell what format the table takes. I have loaded my function as a table, and it comes up in a list when choosing to apply pressure with a table value. Can I actually see this table, so I know which columns to plot?

The function is of the Y variable only (which I am hoping is theta in a local cylindrical co-ordinate system), so I would like to plot function value against Y.

Thanks again.

Hi,
you can see the tzble via "Parameters -> Array Parameters -> Define/Edit -> Edit".
In fact, when you defined your function, you first saved it to a function file and then imported it into a table.
