Refer to the following example from the Fluent UDF Manual. See attached screenshot of the Ansys Help Viewer:
Raef also has a video on pressure inlet condition using a UDF:

THIS IS KNOWN TO ME BUT IS THER ANY METHOD FOR DEFINING PRESSURE GRADIENT

As has been posted in response to other questions, the UDF manual is a good starting point, and from there you will need a DEFINE_PROFILE to set the pressure. You are also not defining a pressure gradient, Fluent will calculate that, you need to define the inlet pressure, and possibly the outlet depending on what you're modelling. Given blood is incompressible, I'd consider using a velocity boundary, again referring to the UDF manual and DEFINE_PROFILE example.

SIR I HAVE WRITTEN ONE UDF CODE BUT GETTING ERROR
ERROR IS fluent/14.0.0/src/dual_cell.h:
line 1 : parse error.
I WILL ATTACH MY UDF FILE

You need definitely to attend a basic C workshop and UDF training. "mu" is not defined and there is line missing ";". That was exception looking into your UDF.
