UDF to define source term at every grid point -- CFD Online Discussion Forums

September 21, 2006, 12:32	UDF to define source term at every grid point	#1
Ralf Schmidt Guest Posts: n/a	Hi! I want to write an udf, that defines a source term (eg. inertial resistance for a porous zone) at every grid point. The values are not divided even, so I will load a table, were for every grid point the value is defined. Now, how to write that udf?? I will read the grid point coordinates in an external programm (matlab) and calculate the value at every point. How that works, I do know... Any Idea for the other problem?? Ralf
