Space- and time-dependant heat flux via UDF
I am currently trying to simulate a laser beam moving along the surface of a flat plate.
For this purpose, the heat flux at the boundary has to be a function of time and space.
As a first try, I would like to set up a quasi-2-dimensional test case.
Thus the heat flux should follow the equation
I_0: intensity of the beam
x: direction of the movement of the laser beam
x_0: starting point of the laser beam
t: simulation time
v: speed at which the beam is moved across the surface
b: width of the laser beam
I found a few examples of UDFs varying a variable in time OR space, but not both at the same time.
Since I am new to UDF programming I would really appreciate your help.
Really? No ideas or suggestions?
For those who might be searching for something similar:
Some of the signs in my equation were wrong, the UDF now looks like this:
The UDF in my last post does what I need.
But thanks a lot for your offer.
i want to model a heat transfer process in which the heat flux of the wall varies with time.
do you have any example?
i am new in udf.
thanks in advance.
