with my contact pair problem with electric current and structural physics module while i am simulating it runs for about
Solution time: 4745 s. (1 hour, 19 minutes, 5 seconds)
went for 23 iterations and give the error of as follows Undefined value found. - Detail: Undefined value found in the equation residual vector.

anyone help me on this issue to get output and to reduce the simulation time .
herewith i am attaching my convergence plot

Try using 'plot while solving' with the plot updated for every iteration. That may give an idea about what is going wrong.

Thanks Henrik Sönnerlind I am a beginner to comsol, can you tell me where i will find this plot while solving option and what is the function of this ? Thanks in advance.
