Dear Sir/Madam,
I am handling structure mechanics problem. I want to extract Mass, Damping and Stiffness matrices. I have started with stationary (static) problem (for simplicity). My problem is solution given by MATLAB with comsol does not match with the solution given by extracted matrix operation (I followed the steps given by "Livelink for MATLAB" user guide version 4.3b example given on page 141-142 of Chapter 4).
I have attached my m-code.
What do I expect: Can you please tell me why my U and U1 (in m file) does not match ? What I am doing wrong? I would also like to ask that why do i get stiffness matrix with very high condition number ?
I am new to comsol as well as structural Mechanics problem.
With Regards,
Harsh.
