fluent doesnt read 1D coating mesh - advice needed

FuzzyDice · July 5, 2011, 14:00

First of all i want to say hello to everyone here, this is my first post on the forum.

I have a little problem with fluent.
I made a simple 2d mesh i catia and im exporting it as bulk data file and importing it in fluent as nastran bulk file. Everything is working fine, fluent reads the mesh and i can solve it.

but i did a 1D coating mesh in catia to one line of my geometry so i can set it up as a axis in fluent (because when i separate my mesh with angle option, fluent seperates the whole line into a zone and i just need to set up one part of that zone as axis and other as wall, and when i separate it with "faces" options i get abou 500 zones!).

when i import it in fluent the 1D coating mesh doesnt seem to be there.
any ideas?
thanks

well i just changed the geometry. i did a mirror over the axis that supposed to be boundary condition as axis so there was no need for that axis any more. all i was left was boundary conditions wall, inlet and outlet velocity

i know its not really helpful because my domain was really small (it was a college assignment) so when i doubled it computation time was few seconds longer. but i was approaching the deadline so i had to improvise
