Hello, I am a graduate student who has just discovered FiPy, and I am working through the helpful examples. However, I am uncertain how to describe an initial microstructure using FiPy (e.g. spherical particles randomly dispersed in a matrix). I am relatively new to the world of computational materials engineering and I would appreciate any advice on how to proceed, especially if there are external resources I should look at. Thanks in advance.
Best regards, Ryan
