Hello everyone! I am using Hystrath for rarefied gas simulation. There are two general boundary conditions in my DSMC simulation. When I use dsmcFreeStreamInflowPatch, the simulation can run.Then I want to use the nozzle plume boundary flow field as the boundary condition for DSMC simulation, which is spacing varing. Once I change gasFace boundryModel to dsmcFreeStreamInflowFieldPatch, there will be an error when running. The error description is
' Cannot find patchField entry for fairing
file:/test/0/boundaryNumberDensity N2.boundaryField from line 27 to line28 '.

Here is the boundary code I used:
