HI All,

I declared few global expressions and would like to plot them. When I go to postprocessing mode ->global variables plot and select the global variable I wish to plot, it returns an error message 8032: eeffmg is not a valid global expression (eeffmg is the name of my global expression). But I already declared it as a global expression! What can 'not valid global expression' mean apart from declaring it global variables?

Any tips on how to work around this problem? Did this happen to any of you guys? I attached my model file, please tell me if I should make any changes to it.

Thanx in advance!

Rajesh.

You have to start back tracing why eem... can not be evaluated. First e3 can not be evaluated so term1 is not valid, and so on.

Firstly, Thanx for your reply Danial. I appreciate it.

I declared e3 as a constant. You think it should be declared as a global expression?

Secondly, I think I figured out what the problem is. The variable 'z', which I was using with parametric solver is a user defined global expression and not an expression intrinsically defined in the model. When I simply replaced 'z' with 'nu_emqvw' (declared as frequency in the model) and keeping everything else the same, I could successfully do a global variables plot. Can you think of a way to work around this problem?



Regards,
Rajesh.

Hi

Yes be careful with naming, there are a lot of simple lettres that are used and have speicif significations such as
i, j, p, s, t, T, u, v, w, x, X, y, Y, z, Z ... and many more, and these are also case sensitive.

Have fun Comsoling
