arbitrary shape with curved edge

Submitted by manjura on Fri, 06/28/2013 - 00:25

Hello all,

I need to put particles on a curved surface. In OpenFoam I can do that easily using blockMesh, but for DEM part, how can I create the wavy region to insert particles?

I used gmsh to create the curved surface with the same coordinate i used in blockMesh and saved them as .stl file to read by DEM.

When i run the file it shows the following error:
ERROR: Fix insert/stream (id ins): command requires a planar face for insertion (fix_insert_stream.cpp:230)

How can i insert partcle in a curved/wavy surface.
Any suggestion will be appreciated.
