Meshing a half spehre

Hi together,

i want to mesh a half sphere and i have two problems (till now):

1. To create a half sphere (only the outer face) i created a sphere (solid) and tried to cut it with a plane. Unfortunately, that was not possible. My workaround is to create a box and subtract to sphere from it. Afterwards i use the explode function. Finally receive my half shell sphere. This way is not very fast and i suppose there is better way. Has anybody an idea?

2. I tried to mesh the sphere with trias and quads. With trias - no problem! But with quads i receive a mixed mesh (quads and trias) and it looks not very nice. Has anybody an idea how to mesh a half sphere only with quad elements in salome?

I attached my model for those that want to have a look!

Thx for your help and merry Christmas,
