FNMB error(cooling chanel for blade)

mohsenrahmani · March 28, 2014, 02:03

Dear all
when i define solid body for a gas turbine blade in autogrid 5 and add separator or film cooling holes i have problem with FNMB.
can anyone help me?

which part of your domain is FNMB? around holes or the blade blocks?

i have the error without holes too

After mesh generation in AG5, check the boundaries.
Try removing (or at least minimizing) the number of NMB boundaries through changing the mesh distributions.
the solver has problems with some NMBs.

regards
