Hello!

It's a great tool you built there! I'd like to use it for some kind of topology optimisation.

Thanks!

Is there an "idiomatic" way to set the material parameters of individual nodes?

The material parameters can be given in general by a function of space and time, and are evaluated in the Gauss quadrature points, not in the FE nodes. It is possible to project the parameters given as the function into the FE space (the nodes). It is also possible to have an auxiliary FE field defining the parameters and use it to evaluate the parameters in the quadrature points.

What exactly do you want to achieve?
