How to build a single-layer SPH particle array

      Hello everyone.
      I have two cylinders nested inside each other. The inner cylinder (red) is 300 mm in diameter, and the outer (black) is 2 mm thick.
      Both cylinders are made of SPH particles.
      How can I configure the outer cylinder to have a single layer of the specified size, for example, a 2 mm thick cylinder? The system won't let me build particles on the outer cylinder larger than 0.05 mm, resulting in a total particle count of over 3 million.
      Thank you.

      Hi, 

      For outer part, have you tried using the shell node based SPH creation?

      Cheers, Ram
