Using fluent
Problem : 2D flow rectangular pipe. Compressible (Sutherland being used at 4 th updating step)
Walls adiabatic and axisymmetric...
Inlet : massflow udf ( oscillating function) with 80k
Outlet : massflow udf with -30 phase angle(with inlet flow) and temperature of 300k.
I couldn't set temperature as it is inactive in the dialogue box.
Expecting answers with procedure
Step1- simple steady condition
Step2- transient piso
Step 3- udfs
Step 4 - Sutherland...
But we are facing floating point error and amg solver divergence... at 3rd step.... We might solve error with setting temperature at outlet....how???
Thanking in advance...reply as soon as possible..


Couldn't be able to attach a contant temperature in in udf... Found many variable temperature profile... Would be helpful if tells about const temp udf....
