Dear group, thanks for your time to review this email.
I have queation about the ways to get derivative of stiffness matrix with density. Currently,I have the stiffness matrix A an density vector v. If I know the constructing process of cell matrix in code,how should I calculate the derivative of stiffness matrix with density? A is a 4131*4131 matrix,v is 1024*1 vector. After derivative calculation the result is a 4131*4131*1024 matrix and a Jacobin matrix,if I am wrong ,please provide your suggestions. Is there any similar examples written in tutorial in dealii? Could you please provide any hint or suggestions? This program is based on cook_membrance.cc https://www.dealii.org/current/doxygen/code-gallery/Quasi_static_Finite_strain_Compressible_Elasticity/cook_membrane.cc Through the program the detail of cell matrix with density can be seen.
