silo flow

Asked by Maciej NIedostatkiewicz on 2010-12-09

I need to simulate the silo control flow: rectangular silo 20x7x50 cm, filled with grains with dimension 5 mm and 1 mm. I am interested in observation the shear localisation along silo walls and changes of the T (shear) and N (normal) forces along the silo wall. Till now I prepared the model in *.stl, so I stopted due to lack of code. Have You any experience with this problem, I will be very gratefull for any answer. Best regards Maciek

Hello Maciej,

Maybe you will need to state more clearly which is your problem ? With your .stl, you should be able to define easily in Yade, the geometry of your silo with "facets" elements : have a look at https://www.yade-dem.org/sphinx/yade.ymport.html?highlight=stl#yade.ymport.stl

Then you will need to define your spheres, and other features of your model.

To resume, the code which you'll need the most is probably the python instructions of Yade (to define which elements you want to have in your model, and so on..), give a look at https://www.yade-dem.org/sphinx/ in general...

Good luck !

you can also import .gts and .gmsh files. I know that Łukasz
Skarżyński uses gmsh for abaqus.

I am also actively using gmsh and very satisfied with it.
.geo files are simple and readable, gooв for parametric models.
