Hello,
Do you know how to get numpy and scipy to work from within abaqus?
Thank you in advance,

Interesting question. Let me add another question wrt Abaqus. I know that you can export element matrices in MatrixMarket (*.mtx) format. How about system matrices ?
Nils
You can generate matrices representing the following model features: stiffness mass viscous damping structural damping, and loads In Abaqus 6.7 use the following option to generate the stiffness matrix, etc. *MATRIX GENERATE, STIFFNESS *MATRIX GENERATE, MASS *MATRIX GENERATE, VISCOUS DAMPING *MATRIX GENERATE, STRUCTURAL DAMPING *MATRIX GENERATE, LOAD For details see section 10.3.1 of Abaqus Analysis User's Manual Volume II: Analysis Generated matrices are output to a text file. The assembled sparse matrix operator data are written to the text file as a series of comma-separated lists. Each row in the file represents a single matrix entry; a row is written with the following elements 1. Row node label 2. Degree of freedom for row node 3. Column node label 4. Degree of freedom for column node 5. Matrix entry For load matrices, which represent right-hand side vector data, each row in the text file is written with the following elements: 1. Node label 2. Right-hand side vector entry. Nils
