How to mesh a cylinder in a square channel using elmergrid?
Posted: 30 Sep 2020, 23:53
I have been studying the ElmerGrid and ElmerTutorial manuals. I wish to model a pipe with internal heat flow and cooling fluid on the outside in a square flow channel, as would exist in a single tube of a heat exchanger. Tutorial 11 of the manual entitled "Thermal flow in a curved pipe" gives me the pipe part, once I eliminated the "curve", LOL. But I am stumped as to how to warp a square channel around the pipe in this example. Eventually I would like to replace all the holes in the example of P-23 of the Elmergrid manual: Square with holes: holes.grd with pipes, but for now I will settle for just a single channel.
Would I just use the "new Mesh" feature? I could not find an example of it's use in the manual.
start New Mesh
The format includes the possibility to generate multiple meshes using one input file. This keyword
invokes the start of a new mesh. All properties are inherited from the previous mesh and therefore the
new mesh may be defined only by few changes.
