Adjustment: meshing by point discretization (on the points)

Introduction

To adjust the mesh, the user can set the node density in the neighborhood of the points.

Information related to the node density next to selected points is assigned to the points; we use the phrase “mesh adjustment via the points” or intermediate of mesh points.

Principle of adjustment “via the points”

The principle of “mesh adjustment via the points” is illustrated in the example below.

• the user imposes a length of 1 mm on the left point and a length of 5 mm on the right point
• the program subdivides the line according to this information: the first line element in contact with the left point has a length of 1 mm and the first line element in contact with the right point has a length of 5 mm. The program arranges the nodes between the two points, following a geometrical progression.

AIDED_MESH POINT

For each project, the software creates an « aided_meshpoint » instance dedicated to Aided mesh.
