Importing an STL file

I have made a model of a reactor in SOLIDWORKS that has some complex geometry modeling a flow straighter. I was able to put in all the regions and boundary conditions that i wanted. However, for some reason i am unable to get it to run. Are there any suggestions on running jobs with complex geometries? Biomass_project.mfx (15.4 KB)

Is the stl file in ascii format?
How many triangles facets are?
Make sure to scale it properly to the desired size , locate inside the simulation domain and you may check it with paraview.
Check the output file to see the stl output and modify the settings accordingly.

Hi i was able to find a solution that works for modeling flow straighteners using mfix. Here is a screen grab of what my vtk output looks like

Hello,

Would you like to share how you were able to run this job with complex geometry please? I’m working on a similar project and have not found a way to do so yet. Thank you!
