I have user defined Interpolation function defined in Global Definitions but I can move it if necessary. The function name is userfunc1.

When I draw results from study, I can plot temperature for example when I set Expression as "T".

But I need to plot userfunc1(T). When I set Expression as "userfunc1(T)" I get error "Unknown function or operator". When I set Expression as "root.userfunc1(T)" I get the same error.

Any advice how to use user defined function when plotting results?

Hello Michal,

Have you done an "Update solution" (under the Study node) after specifyng the function? That could be the reason.
