Boundary conditions for T_modes #47

Closed gianmarioperrucci closed 6 months ago

gianmarioperrucci commented 6 months ago

Hello, I'm having trouble applying a condition to the T_modes.

I'm using as boundary condition "WallBC_NoSlip_UserDefinedT:new{Twall="BC_temp.lua"}", where BC_temp.lua contains:

function interface(args) elem = sampleFluidFace('u',blkId,args.i,0,0) --unstructured 2d grid Twall = 300 inter = {} inter.T = Twall inter.T_modes = {Twall} inter.massf = elem.massf return inter end

I read in other test cases that you need just to define inter.T and inter.T_modes, but without providing also the massflow the simulation does not start because of nan in the concentrations.

Thank you for the help.

Hi Gianmario,

This was in fact a bug, thanks for finding it. I've fixed it in e74443709eb32b46bc3ef49d6a85188f78ae357c.

You should be okay to keep running with setting the mass fractions manually, but it shouldn't crash if that isn't done anymore.

Nick,
