+<li><b>Name</b> - allows to define the name of the hypothesis (BLSURF
+Parameters by default).</li>
+
+<li><b>Topology</b> - allows creation of a conform mesh on a shell of
+not sewed faces.
+<ul>
+ <li>"From CAD" means that mesh conformity is assured by conformity
+ of a shape.</li>
+ <li>"Pre-process" and "Pre-process++" let BLSURF software
+ pre-process the geometrical model to eventually produce a conform
+ mesh. </li>
+</ul>
+
+<li><b>Physical Mesh</b> - if is set to "Custom", allows to set size
+of mesh elements to generate.
+</li>
+
+<li><b>User size</b> - size of mesh elements to generate. </li>
+
+<li><b>Geometrical mesh</b> - if is set to "Custom", allows to set
+mesh element deflection from curves and surfaces and element
+size change rate. </li>
+
+<li><b>Angle Mesh S</b> - maximal allowed angle in degrees at a mesh
+ node between
+<ul>
+ <li> the mesh edge and the tangent to the geometrical curve. </li>
+ <li> the mesh face and the tangent to the geometrical surface. </li>
+</ul>

+two adjacent edges. </li>
+
+<li><b>Allow Quadrangles</b> - to create quadrilateral elements.</li>
+
+<li><b>Patch independent</b> - if this box is checked on, geometrical
+edges are not respected and all geometrical faces are meshed as one
