Dear Sir<BR>
<BR>
I have used gmsh to generate the mesh of pump, but there are two questions.<BR>
1. The volute have a lot of small surfaces that I have to sew, does gmsh can <BR>
do this? How I can do this? By th way I used the *.stp model.<BR>
2. After I use the refine, then I use the optimize that the code shown error and closed. Does it the bug?<BR>
<BR>
