syavash is on a distinguished road
Dear Foamers,

I have a utility which is able to apply non-uniform velocity profile at the inlet. I have little knowledge in C++ so I could not find the solution myself.
When I set the profile as for example "2 * c[1]", which c is the face centre of the inlet boundary, it is compiled using wmake and works. But I do not exactly know how to introduce an if-clause into the code. The p in the following code is a vector class which should be same velocity vector:

I know that this problem originates from lack of programming skills.
Please, can any body suggest something to resolve the problem??

Thanks,

Quick answer: I had this on my to-do list and only now managed to take a quick look into this.
I don't know if you've solved this issue already or not, but the correct way to implement what you want to do is with an explicit boundary condition class.
You can find an example here: http://www.cfd-online.com/Forums/ope...tml#post446451 - post #10

As for the error message, I think it's because you're using "double" variable types when you should use "scalar", e.g.:
Code:
scalar del = 0.89 * 0.0315;
scalar B = 1.0 / 7.0;
scalar ufree = 6.355;
if (c[1] <= (scalar(0.0315) + del))
In addition, I see that you got an answer for a related issue, namely component assignment: http://www.cfd-online.com/Forums/ope...tml#post557666 - post #8

Thanks Bruno,
I have tried groovyBC instead and it is much better to handle.
In the thread you addressed, I had already acknowledged more about variables and classes in OF, but it issued a post-processing problem.
Begginer in OF, lots of questions 😊.
