[Commercial meshers] Regarding MFIX

phani45 · May 25, 2015, 00:39

Hello friends,

I'm planning to work on a problem involving gas-solid fluidized bed with internal heat exchanger (electric rod, tube heat exchanger etc....). I'm willing to use MFIX software as I found that it is most preferred over other Open source software.
My concern is about modelling and meshing in MFIX.
Can anyone let me know whether we can generate complex mesh is MFIX? or shall I shift to any other Open source software?

Um, I heard of it but never use it, seemingly MFIX is powerful on two-fluid model. Thats all what I know..

If someone can give a comment in detail such as is it robust? can MFIX deal unstructured-mesh? That will be better.

For moderately complex geometries, you can use predefined shapes (quadric surfaces) to represent cylinders and spheres for example. For more complex geometries, you can use a CAD software to generate an STL file and import it in MFiX.

MFiX uses a structured mesh, and the complex geometry is represented using the Cartesian cut-cell technique.

Thank you Jeff

Can we import the mesh created in other software like open foam into mfix????

Did you figure out if and how it is possible to import OpenFOAM Meshes to mfix?
