I'm studing granular media and fluent works with a multiphase  Euler Granular model.


In the post process, fluent returns a "Granular Pressure" and tree ¿tensor? more components : Granular Pressure G X Cmpn , Granular Pressure G Y Cmpn, Granular Pressure G Z Cmpn. They don´t have units.

Does anyone know the formal (mathematic) definition of this field???


Thanks in advance
