I want different units to set different elastic modulus. What should I do？Thanks！
Hi,
the code assumes consistent units of all parameters, so you can use any mutually consistent units you want, but all quantities must be defined in those units.

I directly set the modulus of elasticity in matrix form, but the result of the element stiffness matrix is incorrect. What is the problem? Or how can I interpolate the stiffness matrix externally and then input it into sfepy to calculate the overall stiffness matrix.
Sorry, there is something wrong with my initial statement. What I mean is that different grid cells have different elastic moduli.

I see, have a look at [1],[2]. If you only have a few regions that have different material parameters, you can use the second example shown in [3].
Cheers, r.
