Hi,

I am trying to implement parabolic velocity boundary condition at the inlet and writing the corresponding codes in the 'u' file within '0' folder as in the attachment.

However, when I run the simulation with icoFoam, I am getting the error message as in the attachment.

I appreciate your help in this regard.


Cheers,
Nazmul

Tobermory will become famous soon enough
I know that the error messages can sometimes feel a little daunting to read, but do try - it literally tells you what the problem is in the first line. You are missing the "name" keyword from your boundary definition (see e.g. https://cpp.openfoam.org/v8/classFoa...d.html#details). Just add something like:

Code:
name    parabolicCodedInlet;
after the type and value keyword lines, and it should work.

Hello,


I have solved the problem. There was a typo in the code. I was written "Patch", but it should have written "patch".


Now it works. Thanks for your suggestion.


Cheers,
Nazmul
