<DIV>Dear developer!</DIV>
<DIV> </DIV>
<DIV></DIV>
<DIV>A nice day to you!</DIV>
<DIV>I am new to GMSH, but I like it very much, it's beautiful and very good, very comfortable to use! I enjoy in mousing over
it.</DIV>
<DIV> </DIV>
<DIV></DIV>
<DIV>Now I met a problem when I am trying to mesh a wall-mounted cube in CFD, more defnitely I am using DES (Detached eddy simulation).</DIV>
<DIV>I need to know exactly the spacing in streamwise and spanwise, and of course in the direction normal to the wall.</DIV>
<DIV>So, I use structured mesh near the cube by putting the cube in a littel larger-size box, and within this box, the mesh is structured so that I can easily modify it in the future.</DIV>
<DIV>But Outside of the box, that is in the wind-tunnel, I want to use unstructured grids. However I met many errors here. (2D mesh is ok, but 3D crashed!)</DIV>

<DIV>And Could you tell me how to effeciently write a geo file as in my case, and
am I in a good style for GMSH-scripting?</DIV>
