Invoke other variables in user defined reaction

MFiX
#1

Hi, Developers

As a new user, i want to know that if it is possible for user defined reaction to invoke other variables, such as volume fraction and ratio of diffenrent species of particles. As you know, the reaction in the bed, sometimes, may be relevant to the volume fration of solids. This function is available in the commercial software CPFD, by offering a template containing these variable mentioned above .

I really want to know if MFIX can do what CPFD can do and even can’t do.

Best regards.

“Open source MFiX can do anything if you are good enough!” :grinning:
For PIC/DEM reactive chemistry
See tutorials\pic\silane_pyrolysis_3d\usr_rates_des
legacy_tests\dem-tests\reactive-chemistry\usr_rates_des
All you want is there.
EP_G(IJK) ! gas volume fraction
DES_X_S(NP,species_index) ! solid mass fraction of each species
