"No solution was found" error with MathCAD 15.0

"No solution was found" error with MathCAD 15.0

Hi Everyone,

 

New MathCAD 15.0 user here having trouble resolving a “no solution was found” issue in the attached file.

I'm trying to solve the equation for "y".  

"x" is the independent variable and is greater than zero.

All the Greek letters are constants that are also greater than zero.

 

From the looks of it, the solution should be some sort of Lambert-W function, and since everything is positive, the solution shouldn't have any imaginary component.

 

Any help would be appreciated!

Mathcads symbolic (muPad) simply isn't capable to solve that equation symbolically.

 

Given specific values for the constants and x Mathcad may be able to find a numeric solution using a solve block or the "root" command.
