Hi
How i can get an internal emissivity through UDF?
Is any function which works similar like f. ex. temperature: C_T(face, thread).
thanks.

use DPM_EMISSIVITY(p,m) to get the particle emissivity.

Use THREAD_VAR(t).wall.in_emiss to get the internal emissivity of a wall.

Return value: Profile structure type

Use the following method to get the emissivity (absorption coeff.) of internal gas

Thread*t;
Material *m;
real as;
Property *prop;
m=THREAD_MATERIAL(t);
prop =MATERIAL_PROPERTY(m);
as = generic_property(c,t,prop,PROP_abs_coeff,C_T(c,t)) ;

Would you write a full structure udf to get this parameter?
