I have a structure ( i.e. a crane ). I split the structure in a certain number of simple elements ( shaft or beam ). For each element i can build a local stiffness matrix of 12x12 element. Then i need to assembly this little matrixes in the big structure matrix. Dimension of the structure matrix is equale to: ( number of nodes x 6 ). nodes are cross point between elements. Each element matrix has a specifical location in the big matrix. How i can assembly the big structure matrix, starting by the single element matrix ? What i want to input is only the dimension of the structure matrix and the data of each single element matrix. The big structure matrix should be calculated by Mathematica. Thanks in adavance for help and sorry for my very bad english Regards, Francesco
