Dear professor,
Sorry for posting another problem again.
When running Gmsh meshing facility, an eception was thrown out and forced
the program to abort.
It was a very simple geometry only consisting of 12 nodes, 7 surfaces and 1
volume.
The meshing was runing Gmsh v1.58.0 on WinXP SP2 . Below are info. about the
files of cube.geo and .gmsh-errors and stack trace. Please help me to
diagnose.
(Maybe the height value of the cube is too small according to the
gmsh-error, but the msehing result of the same text based geometric file can
be generated by DEQSOL,which is a Fortran 77 based Japanese simulating
application without visualization function)
Many thanks
