Dear Foamer,

I am using codeStream for one of my B.C.'s and the problem is it just compiles and runs the codeStream at t=0 and after that, it is not changing the B.C.

My B.C. depends on the temperature of the patch and I wrote it as a function of the temperature of the patch but the temperature doesn't update and it just takes the initial temperature and calculate the filedPatch at the beginning.

I also check it out by adding following code to see if it runs the codeStream everytime or not:

Info << "HELLO" << endl;

well it just runs it at the very beginning right after the compilation not anymore during the simulation.

Can anyone please help me to know how to make codeStream run in each iteration and/or timestep?

Thanks in advance,

P.S. I have used codedFixedValue for another B.C. and it runs in every iteration but here I am using codeStream inside directionMixed and I cannot use codedFixedValue

Hi,

did u find a way to accomplish? I face the exactly same problem.

Hi,

I finally gave up and now I am pretty sure that codeStream does NOT update during runTime. I used defining BC inside my solver Code. following threads are helpful for doing that.

Hi,

I found that for me, codedFixedValue works. You can check some tutorials online.
