EMAT simulation simple

Please login with a confirmed email address before reporting spam

Dears,

I'm new to COMSOL. I am trying to do a very simple simulation of an EMAT transducer
The modules I use are:
Magnetic Fields, No Current,
Magnetic FIeld,
Solid Mechanis,

I have some questions.

1) My solid mechanics results are not being made, when I plot some result (example solid.sz) my white graph, I do not understand this.

Another question

2) I want to use a function as a substitute for a variable,

Example: I have a function of current [A] (tone burst signal) created, I loaded the data by a .txt file from the interpolation function, I gave the name t_burts, I defined it as a = local variable:

Name Expression unit Description
t_ burst    t_brust (t) A current

I tried replacing this in the module of mf -> Multi-turn coil in the field of coil current I=t_burst(t)[A]

But the calculations are not being made, and the results are not shown my graph was green.

Regards,
Natalie
