[Bug] Crash SMESH module

Posted by Moise Rousseau at January 04. 2019

Hi !

I would like to report a bug occuring in the SMESH module. I am running the latest release of Salome (9.2.0) on Ubuntu 18.04.

The crash occur when trying to compute a mesh on a geometrical object after its evaluation failed. You can reproduce he bug by following the next procedure :

1) Load the file Geometry_v2_light.hdf (attached). Note this file have been created entirely with Salome and have not been modified by other software. I should delete some intermediaire geom object because of attachment size restriction.

2) Load the SMESH module

3) Open the group Model DP and select the 'Env' geometry

4) create a new mesh with the following algorithm : (3D) Hexahedron (i,j,k) / (2D) Quadrangle mapping / (1D) Wire discretisation and the hypothesis : Max size set to 5

5) Evaluate the mesh (sometime crash here), where the evaluation fail, and compute it (crash 90% of the time)

The terminal output associated the the bug is only : "munmap_chunk(): invalid pointer"


Hope you can fix this bug.

I remain at your disposition if you more information.

Good evening !

The developers are least interested in solving our issues.

I am afraid this structure cannot be meshed with Hexahedron(i,j,k) because it is not similar to a cube.
