Just come across this problem myself and found a useful section in the FLUENT UDF manual. If you have the UDF manual it's section 4.3.17 (note it's in the FLUENT UDF manual not just the FLUENT Users Guide). I think the UDF manual should be in the following folder under Fluent.Inc if the folder structure is the same on your computer as mine;

Fluent.Inc\fluent6.3.26\help\pdf\udf

If not then private message me and I will email it to you.

Ed
