Hi,

Can some one write a UDF code. its very basic.

all i need to do is apply a fixed temperature of 1400K in an axisymmetric problem.

i have drawn it in 2d format.

please plseas Help me with it. Thank you for your help

If the temperature is fixed, can't you use the wall boundary condition and specify a fixed temp? or you can use the fixed values option in your region of interest.

Re: natural convection on wavy curve surface
 
Hi friends, I am doing simulation of natural convection on 2D wavy curve surface. Please please help me in clearly certain doubts: I am using realisable k-epsilon model 1)The Grash-off number is of 10^9 order ....... can i use turbulent model for this buoyancy convection 2)In define -operating condition - one unchecked block for operating density is there , I am using INCOMPRESSIBLE IDEAL GAS,do i need to check the operatind density box or leave it 3)1)the continuity equation in not converging (over 6000 iterations), which under relaxation factors I need to alter ,should I decrease or increase the under relaxation factors plz tell exactly or atleast their combinations. PLZ PLZ PLZ HELP.
