Summary | 0031449: Mesh - BRepMesh works too long and produces many free nodes on a valid face | ||
Revision | 2020-03-20 10:47 by abv | ||
Steps To Reproduce | 1. Full variant of original sequence in DRAW (hang or too long to wait for): pload XDE AISV ReadStep D [locate_data_file bug31301.stp] WriteStep D bug31301_exported.stp param xstep.cascade.unit M ReadStep Q bug31301_exported.stp XShow Q ----> WAIT (forever?)! 2. Simplified variant (prototype of test case) using single face (one that caused problems in #31301) already passed through all import - export steps: pload MODELING MESH restore [locate_data_file bug31301_face_loopback_M.brep] a checkshape a tolerance a dchrono s restart incmesh a 0.0001 dchrono s stop show # meshing must be fraction of second, takes ~ 30 sec tricheck a # 6.000+ free nodes 3. Reproduction of the situation of CAD Assistant that eats ~ 30 GB of memory in ~ 3 min (on 6-core CPU): pload MODELING restore [locate_data_file bug31301_2_exported.brep] a incmesh a 0.00039624 -a 20 -min 0.0001 -parallel (the file is attached to #31301) |
