Thank you Dr. Wolfgang Bangerth, I have successfully applied boundary conditions at the extreme node of 1-D bar but not able to impose it on intermediate points. I have following doubts- 1. How to check boundary ids and assign boundary values corresponding to any intermediate node? 2. In the solution file (vtk), 4 points can be seen instead of 3 for 2 elements. Why is it so? 3. How to alter the output parameters/variables given in the solution file?
