Dear all,

I am trying to simulate a case in OF, using the chtMultiRegionFoam solver.

I have `a slice' of the whole domain and on the lateral faces I want to impose a symmetry boundary condition.

I get this error

but I can't understand what's wrong.

Could you help, please?

Thanks a lot,

Greetings Samuele,

You're opening a lot of threads about chtMultiRegionFoam... although it might look easier for you to ask questions this way, it makes a lot harder for people to answer and for others to look for the same answers...

Now, let me read again your question on this thread... Ah, right. The problem here is this:

boundaryField::.*

The ".*" is a regular expression that is used for selecting any and all boundary fields, independently of their name. Search online for "sed tutorial" or "regular expressions tutorial" for more information on this. The OpenFOAM User Guide probably also mentions how to make use of regular expressions.

Anyway, since you're using a regular expression, means that the definitions made within that block will apply to all boundary fields. This cannot be done in some cases, like what happened in your case.

Now on to another thread ...

Best regards,
Bruno

Dear Bruno,

once again, sorry for the `spam'.. I thought it was better to open a new thread for each question.

So, let's move to this thread. Do you agree?

Thanks,

Samuele.
