why can not two udf.s be used?
 

Hi! i want to model a melt and VOF process, need to use heat flux'udf and momentum source term'udf at the same time,but after they are compiled,it appears following errors:

Error: chip-exec: function "cell_z_source" not found. or

Error: chip-exec: function "heat_flux" not found. can FLUENT only use one udf? how to use two udf at the same time? Thanks!

print your source to see if there is a mistake...

is it necessary to use two udf's?

you can write all in one udf and hook where ever you want

Are you using V6.2? or earlier version? V6.2 seems to be fine with multiple udf libraries.

I am using V6.2. may i write one heat flux source term and one z axial momentum source term in a udf file?

Sure. Make sure each each one works though.
