Tdyn wizard helps you to easily generate control volume around body or bodies, assign the main data , generate a mesh and perform the simulation . Moreover, Tdyn wizard will help you in the post-processing and reporting the results.
Tdyn wizard can be accessed at any time through the menu option Data > Problem wizards > Tdyn ... .
To make the Tdyn wizard understand the problem, the geometry body has to be split in different layers as described in the following steps.
Layers split a drawing into separate pieces. Every entity can only belong to one single layer.
Following are different cases of problems solved by the Tdyn Wizard:
|
|
||||||
Case 1. Semi-submerged floating body with free surface. Geometry and boundary conditions with symmetry in y=yo plane. Main flow in +x or -x direction. RANSOL and NAVAL modules required. |
Case 2. Submerged body without free surface. Geometry and boundary conditions with symmetry in y=yo plane. Main flow in +x or -x direction. RANSOL module required. |

Case 3. Semi-submerged floating body with free surface. Geometry and boundary conditions without symmetry. Main flow in +x or -x direction. RANSOL and NAVAL modules required |
Case 4. Submerged body without free surface. Geometry and boundary conditions without symmetry. Main flow in +x or -x direction. RANSOL module required. |

Layers window can be accessed through the menu option Utilities>Layers .
Detailed information on how to create geometry can be found in the help section Geometry (Help>Help ).
Following is the list of basic commands, available in the Layers window (see Figure 19):
New : Create a new layer. A new layer will automatically be selected as ‘Layer To Use’.
Layer To Use : Select a layer to be used as default. All new geometry entities will be created within this layer.
Delete : Delete a layer. A layer can only be deleted if it doesn’t include any entities.
Rename : Change the name of a layer.
Send To : Moves entities to a new layer. No new entities are created.
