Assign Boundary conditions using utility
Hi all,
Im trying to create a utility which will initialize my fields and set the boundary conditions on my fields. I am having trouble assigning the boundary conditions because even though I assign "fixedValue" it will show as "calculated" instead when written to the 0 directory. Here is my code. How can I assign the boundary condition and have it write out correctly?
Thanks,
Tony
