Hi everyone,

I try to introduce a new list (named vorticityMode0_x ) in my solver, but I can't compile the code. The list has to handle parallel calculation. Here's what I wrote :

List<scalar> vorticityMode0_x(Pstream::nProcs());

vorticityMode0_x[Pstream::myProcNo()].setSize(nLim); // Problem seems from this line

vorticityMode0_x[Pstream::myProcNo()][nxyI] = inX[0]/nz;

Pstream::gatherList(vorticityMode0_x);

Here's the error message :

Thank you very much for your help,

Greetings Pascal,

I might be wrong, but I think what you want is this:

List< List<scalar> > vorticityMode0_x(Pstream::nProcs());

At least that's the idea you're giving with the remaining code!

Best regards,
Bruno

oups... Thank you Bruno!

I was wondering if you knew what is the simple way to merge all the lists from every CPUs into a single list readable by the master CPU?

I though gatherList() was doing it but it seems that it only make all the lists visible from the master CPU.

Thank you
Pascal
