Hello,

I am writing a udf on C.. for change in material property using command
DEFINE_PROPERTY

can i also use the command DEFINE_SOURCE for change in momentum equation in the same program?

I've never used these macros but don't see why not, have you tried it to find out?

you can use DEFINE_PROPERTIY and DEFINE_SOURCE, for change a material property and the source term of the momentum equation respectively. for do this, you have write both UDF in the same archive c.
