| Summary | 0031449: Mesh - BRepMesh works too long and produces many free nodes on a valid face | ||||
| Description | The shape analyzed in context of #31301 exhibits problems in meshing occuring after export of the original shape (initially imported from STEP) to STEP and importing back, in a case when parameter xstep.cascade.unit is set to meters during last import. The meshing takes enormous time (effectively hangs) and (when suceeds) produces a lot of free nodes. Originally detected in CAD Assistant which just hangs and eats all available memory when reading the exported STEP file if unit settings are "M". | ||||
| 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) | ||||

It is strange, but reported free nodes are all visually located out of face boundary (see attached screenshots). To be analysed. |

The issue is not reproducible anymore on current master. Branch CR31449 contains test cases only, see the report: http://jenkins-test-occt/view/master-CR31449-OAN/view/COMPARE/ To integrate: OCCT: CR31449 PRODUCTS: None |
|
|
Please do not make test failed due to exceeding execution time. Instead use cpulimit with some large enough threshold to pass the test on a low end PC or in debug mode. |
