-- For some creo models created with Creo 7.0 there comes unmerged faces in non manifold model. These models give self intersecting mesh error during meshing.
-- These models are creating correct non manifold model with Creo 4.0 as well as meshing successfully.
-- To resolve unmerged faces issues with creo 7.0 define variable sim_split_geom_cntrs yes in config.pro file of Creo 7.0 version that is used with CAENexus. PTC has suggested this workaround with Creo 7.0
