<DIV><FONT face="MS UI Gothic" size=2></FONT> </DIV>
<DIV><FONT face="MS UI Gothic" size=2>Sorry for posting another problem
again.</FONT><FONT face="MS UI Gothic" size=2> </FONT></DIV>
<DIV><FONT face="MS UI Gothic" size=2>When running Gmsh meshing facility, an
eception was thrown out and forced the program to abort. </FONT></DIV>
<DIV><FONT face="MS UI Gothic" size=2></FONT> </DIV>
<DIV><FONT face="MS UI Gothic" size=2>It was a very simple geometry only
consisting of 12 nodes, 7 surfaces and 1 volume. </FONT></DIV>
<DIV><FONT face="MS UI Gothic" size=2>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.</FONT></DIV>
<DIV><FONT face="MS UI Gothic" size=2>(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)</FONT></DIV>
