Hi,

You can set the htc with DEFINE_HEAT_FLUX macro. See your UDF user's guide.

Thanks

Hi,

The macro name is DEFINE_HEAT_FLUX but you can specify the htc in the following way.

DEFINE_HEAT_FLUX(sampe, f, t, c0, t0, cid, cir)

{

cid[1] = your htc;

cid[2] = your htc;

}

where cid[1], cid[2], please see the section DEFINE_HEAT_FLUX.
