Duplicate node/elements problem

marioisaacdsouza · February 9, 2015, 02:08

Hi,
I completed my suface meshing on ANSA and i checked for duplicates and it says there are no duplicates.
When i import my model into Tgrid for volume meshing , when i hit initialize it says duplicate nodes found.
What can i do to resolve this issue and track down the duplicate nodes.
Pls help

Hi there it seems that the problem is duplcate nodes and not duplicate elements.
Before outputting the mesh from ANSA try the Compress command
to delete any unused duplicate nodes,

Hope this helps

Best regards

Vangelis

Hi Guys
I am using ICEM meshing tool but while modelling the geometry i give the inputs like inlet, outlet , wall etc but when the mesh is imported to Ansys the boundary conditions are missing only one boundary condition is there eg wall.
What should i do to get all the boundary condition ?

thank you vangelis.
The problem was with the software . There were a few places where nodes/elements were overlapping but the software did not detect( old version of ANSA). I had to search each part and get rid of it .
