<code>Hello,<br><br>I am new to GMSH and was just going through the tutorial. In the Geometry module, I just happen to come across this point:<br><br>Point ( </code><var>expression</var><code> ) = { </code><var>expression</var><code>, </code><var>expression</var><code>, </code><var>expression</var><code> <, </code><var>expression</var><code> > };<br>
<br>It says that first three expressions on the RHS is x, y, and z values of a particular point. What is <. expression> used for? It is mentioned in the documentation that<br><br></code> the optional last <var>expression</var> sets the prescribed
mesh element size at that point<br><br>Any examples over this issue, so that the element size can be controlled by this optional parameter.?<br><br>Thanks in advance.<br><br>Regards<br>Rakesh Patil<br>
