predefined equations in solve block

[FK_10732959]

Hi, in my sheet i have a set of equations with multiple variables which i have calculated ( around 40 equations). Now I have to solve these equations by equating them to zero in the solve block. I assigned these equations to variables and equated these variables to zero in the solve block. but unfortunately, is not working in the solve block. So now every time i change any parameters in my sheet i have to manually copy all 40 equations to the solve block and equate them to zero in the constraints.

Is there a simpler way to do this?

Thanks

Hi,  Can you share an example of what's happening? Thanks GeoffD

Assigning the equations (I guess you just mean an expression, not really an equation) to a VARIABLE will work with the symbolics engine, but not in a numeric solve block.

So I would suggest defining FUNCTIONS in all variables instead.

For further help you would have to provide more information, best attach your worksheet.
