Can anyone please help to write the above equation

Y=X0*(1+sin*(w*t))

where

w=2*pi*f (rad/s), t=argument(s)

I have tried with analytical function after defining w in variables and all other constants in parameters.

when I tried to plot it shows following errors:

syntax error in expression
Expression: ()[1/s]
Sub Expression: ()[1/s]
Position 1

Y=X0*(1+sin*(w*t))

try following
Y=X0*(1+sin(w*t))
Y=X0*(1+sin*(w*t)) try following Y=X0*(1+sin(w*t))

Hi

could it be a naming conflict ?
In which physics are you working ?

COMSOL uses many internal variables, that you are often allowed to reuse but then you change the behaviour of your physics.

most single letter names are usedwitrh special menaings i.e. solid displacements such as r,s,t, u,v,w, x,y,z, ...
also in upper cases i.e. "Solid" R,X,Y,Z to differentiate the Frames ...

Good luck
