What is the meaning of the terms in the stiffness matrix?

Hello, world!

Recently I obtained the stiffness matrix and load matrix by 'mphmatrix'. But what is the meaning of each term (i.e., k11, k12..)? The number of the rows in the matrix is much more than I imagined. Thanks.

Best wishes,

Long

The load matrix is also very complex. I cannot find the explaination of it in the manual.
