Hello.

I have two questions:

Q1. I am working on designing 2D axisymmetric emitter geometries. Making a regular cylinder was easy by considering a hollow rectangle.

Emitter with a fillet of a given radius.

However, now I am trying to model an etched emitter that has an outward curve. I cannot seem to work out how to properly create a mesh for this case. Any guidance??

Q2. I have been working with internally fed emitter but how to create an externally wetted emitter as shown below. (a) capillary‐type and B, an externally wetted needle‐type emitter.

For capillary-type, my alpha.water (interFoam) case looks like this:

dimensions      [0 0 0 0 0 0 0];

internalField   uniform 0;

boundaryField
{
.....
    inlet 
    {
        type            fixedValue;
	value          uniform 1;
    }
....

Any help is appreciated,
Thanks
