Hello together,

I have the following expression for a vectorField:

const vectorField buffer=(Up - n*(n & Up));

And I want to set all z-entries to zero.
How does it work?

Thanks in advance!

Best regards

The first one I thought of (there might be better solutions):

vectorField buffer=(Up - n*(n & Up));

// Set z value
for (auto& val : buffer)
{
    val.z() = 0;
}

Thanks for your reply!

I've tested your approach, but an error occured:

error: assignment of read-only location ‘(& val)->Foam::Vector<double>::z()’
  151 |         val.z() = 0;
      |         ~~~~~~~~^~~

Can you help me?


SOLVED:

Remove const in front of vectorField.

vectorField buffer=(Up - n*(n & Up));

my example was without 'const'
