I am trying to simulate the two phase flow in a simple channel with a dead end. When I run the LBPM my solid phase is overwritten by a fluid near inlet. Attached you can find an example.
Are there any geometrical limitations on the shape of the inlet? Do I need to create a dummy cell that is filled with the fluid phase?
I would also be thankful if you could refer me to the source where I can find all keywords for BC.
Thank you

LBPM always assigns the inlet / outlet in the z-direction if you are using an external boundary condition. These
are usually BC=3 or BC=4 for lbpm_color_simulator. This is done so that each region is a contiguous memory region. If you drive the flow in the z direction, then you should be able to run this geometry without overwriting the solid layer.
You could also drive the flow with an external body force by setting BC=0 in which case you can drive the fluids in either the x, y or z directions.
See this link for BC keywords for the color simulator
