Creating a pipe-shaped volume

Submitted by ROK_LZ_FW on Mon, 06/18/2018 - 15:26

Hello,

I'm trying to build a pipe shaped volume for my LIGGGHTS-simulation using the following commands

region cout cylinder z 0. 0. 0.04 0. 0.3 units box
region cin cylinder z 0. 0. 0.003 0. 0.3 units box
region cd intersect 2 cout cin

When I run the calculation I get the error message 'unable to calculate region volume'.
So how is the right syntax to create a pipe volume?
Thanks for help
