Hi GMSH users and developers,

Is it possible to check a mesh in gmsh in the regard of negative  
jacobians? If yes, is it possible to show such elements in gmsh gui?  
Attached a mesh wich has negative jacobians to test with.

mesh: Shape_mesh_negative_jacobian.unv.zip (remove .zip)

What is the recommended way to avoid such negative jacobians? Attached  
the geometry of the mesh above.

geometry: Shape.brep

kind regards bernd
