Particles in different size but same Species

When simulate chemical reactions with Particles in different size (such as biomass different in size but same in Species), the user need to re-define each species for each sized particle. If I want to simulate 3 different sized biomass particles each with 4 same species, I need to define 3x4 types of species instead of just 4. This is very inconvenient. r_2019-05-06T103538.zip (22.6 MB)

To simulate only 4 species, you need to set all biomass particles (with different size) in one solid phase. You need to provide the size of each biomass particle through the file: particle_input.dat
