No tetrahedra in region 1 with a "Surface consists of no elements", but
I am seeing three instances of
Warning : Surface XXX consists of no elements . Inspection in the GUI shows that surface 143 is not meshed but that Surfaces 503 and 845 both have been meshed.
Do you know why Surface 143 did not get meshed, and why I get an error about the other two surfaces consisting of no elements when visual inspection shows that the surfaces have indeed been filled in during 2D meshing?
Some info about what I'm trying to do:
I am trying to mesh the interparticle spacing that arises after the packing of 246 spheres. In order to avoid the issues associated with meshing around contact points I am locally modifying the spheres to ensure that there is always a gap between surfaces. The algorithm is described here and is implemented in salome:
- All sphere-sphere pairs that come within 5 mm of contact are found, 607 in this case
- The 246 nominal spheres are made, as are 246 "boolean tool spheres" that have their radii increased by 5 mm
- A for loop uses the boolean tool spheres to cut away part of original/nominal spheres for each of the 607 pairs
- The set of modified spheres is then subtracted from a box domain to leave the interparticle space, exported as a BREP file
I have attached my BREP, GEO and log files as well as three screen clippings showing the three locations where I get this error.
