I want to extract Mass, Damping and Stiffness matrices. While trying to obtain the torque applied on the body for its certain angular position, I'm having difficulty in solution, probably due to solver setup. http://www.comsol.fr/community/forums/general/thread/20099/

Just make sure that a reputable provider is giving the file copy. Thank you. Contact us about this article Internal error code is 5018. Which one of the tabs I have to change?

The "u" is the mesh displacement of the coupled boundary. Comsol Failed To Evaluate Variable Jacobian Enter your email address below and we will send you a link to where you can set a new one. In one of the subdomains only the heat transfer equation is solved, not the navier stokes equation. I'll look into whether is is the same as extracting the residual matrix from the solution.

When you know the cause, you'll find the solution.

Trouble shooting Comsol Error Failed To Evaluate Variable Jacobian needs the same process. Also don't forget to consider getting a great anti-virus because there are times wherein this error is caused by specific viruses. I have the same problem. Passcodes are often given out for trials.

Philip is exactly right, at least it solved my problem.
