    +
  1. In the \b Mesh menu select Create Mesh or click "Create +Mesh" button in the toolbar. + +\image html image32.gif +
    "Create Mesh" button
    + +The following dialog box will appear: + +\image html createmesh-inv.png +
    2. +
  2. For example, you need to mesh a 3d object. +\n First, type the name for your mesh in the "Name" box, by default, +it is "Mesh_1". Then select the object you wish to mesh in the Object +Browser and click the "Add" button. + +\image html image120.gif +
    "Add" button
    + +Now you can define 1d Algorithm and 1d Hypotheses, which will be +applied to the edges of your object. (Note that any object has edges, +even if their existence is not apparent, for example, a sphere has 4 +edges). Click the "Add Hypothesis" button to add a hypothesis. + +\image html image121.gif +
    "Add Hypothesis" button
    + +Click the "Edit Hypothesis" button to define values for the +current hypothesis. + +\image html image122.gif +
    "Edit Hypothesis" button
    + +The use of additional hypotheses is optional (i.e. you may leave +"None" in this box). + +Proceed in the same way with 2d and 3d Algorithms and Hypotheses, note +that the choice of hypotheses depends on the algorithm. There must be +one Algorithm and one or several Hypotheses for each dimension of your +object, otherwise you will not get any mesh at all. Of course, if you +wish to mesh a face, which is a 2d object, you don't need to define 3d +Algorithm and Hypotheses. +\n In the Object Browser the structure of the new mesh will be +displayed as follows: + +\image html image88.jpg + +It contains: + + +There is an alternative way to create a mesh on an object simply by +clicking Assign a set of hypotheses button and selecting between +Automatic Tetrahedralization or Hexahedralization. The program will +automatically generate a 3D mesh with the most appropriate +settings. In the same way you can apply this functionality for meshing +2D objects, in which case 3D algorithms are not applied.

  3. Now, when everything is ready, select your mesh in the Object +Browser. From the \b Mesh menu select \b Compute or click "Compute" button of the +toolbar. + +\image html image28.gif +
    "Compute" button
    + +The Mesh Computation information box appears. + +\image html meshcomputationsucceed.png + +If the mesh computation failed, the information about the cause of the +failure is provided. + +\image html meshcomputationfail.png + +After you select the error, Show Subshape button allows +visualizing the mesh elements that cause it. + +\image html failed_computation.png + +Publish Subshape button allows importing it in a separate MED +or UNV file. + +NOTE It is possible to define a 1D or a 2D mesh in a +python script and then use such submeshes in the construction of a 3D +mesh. For this, there exist two algorithms: Use existing edges and Use +existing faces. They are not entirely usable from the GUI, so a +mesh created using these algorithms should be exported into a python +script, edited and then imported into the GUi. + +Consider trying a sample script for construction of a mesh from our +\ref tui_creating_meshes_page "TUI Scripts" section. +
