Defining Material Numbers

[michael.gianfelice]

Hi,

I am quite new to openLB. My goal is to run a wind study on a fairly detailed STL geometry consisting of buildings and other infrastructure. I have a domain which is a 36-sided polygon and I wish to make 11 sides inflow and the opposite 11 sides outflow. I read that I have to change the material numbers of the geometry, however, I am not sure what actually has to be defined. What exactly has to be changed in the example code (say aorta3d) and how can I make sure the change is correct?

Dear Michael,

for the beginning, you may set veleocity conditions at the inflow and ouflow domains by just one material number. Please, also have a look at our user guide and the online documentation Doxygen. Further, our spring school is always a good start!

Actual support my group only can offer in form a common project. For this, visit http://www.lbrg.kit.edu and contact me by the email provided there.

Best
Mathias

Hello Mathias,

Thank you for your quick reply!
Where can I access the Doxygen Documentation?

I’m not sure if it is just my browser but that page is blank for me.

My mistake, it is working fine now!
Thank You, Mathias
