Entering an expression that requires an integral

I need to be able to enter an expression that contains a number of variables. One of which is the integral of the term that will be entered in. For example: the expression might be a+b*y, but 'a' is actually the integral of 'adot' which is what is entered as another expression. How would I go about doing this?

Stated another way, I need to be able to enter an expression into comsol, then have comsol integrate the expression before using the integrated value in another expression.

adot would be the derivative wrt psuedotime.

Thanks in advance.
