hi，I am currently working on a model for biomass pyrolysis, and I need to verify the mass fractions of the products. They will produce solid char and gas, and I know that x_g represents the mass fraction of the gas in the monitor. However, the mass fraction of nitrogen gas is also included, and together they equal 1. The mass fraction of the solid is in the species variable, but I’m not sure if the sum of these product mass fractions will equal one, nor how to verify it with the mass fractions represented in the article.
Hi @Qianbinhui
Sorry, I do not know what you mean by “The mass fraction of the solid is in the species variable”
Please upload your case files, and explain more clearly what you are trying to achieve. Thanks!

1.where the quality of carbon is shown as a fraction in the reactants.
2.I wonder how to compare the productivity of data and experiments.
thank you for your reply
Mass fractions and reaction rates can be monitored on either a particle or cell basis:
If you need more detail, you can save data into DES_USR_VAR in your reaction code.
These screenshots are from the Silane pyrolyisis tutorial, since you have still not uploaded your project files.
Comparing simulation and experimental data is up to you, this is not something we can assist you with.
