How to use Design Modeller
It is essential for the student to get around using design modeler in order to get the right geometry to create at a later stage the mesh required for the simulation. Working with the simple drawing tools:
Using the revolve Command
The tutorial covers how to draw splines and then revolve the profile around a specfied axis. He has specfied a static body case to study, for some reason it wasnt clear to me when did he draw the axis to rotate the spline around it, fixtures are applied at the static structue sub tree by right clicking the mouse button and selecting one out of the different fixture options, this tutorial also cover stress analysis, this intended to study solids with the appliction of a simualtion option through an applied force gradient .
Using the Extrude Command
This tutorial has some drawing tips and on how to use the mirror option and finally the extrude command, the contour is extruded and the mesh can be controlled, this also cover some stress analysis material.
Using the Sweep Command
The video shows how to use the sweep command to model an elbo tube.
Boolean Operations
The next video is rich with fundamental
ideals on how to mesh, Boolean operation are used to generate calculation
meshes they are very essential, there are two types of studies meshes ,fluid
meshes and solid meshes, that all depends on the application of interest,...etc.
By using the proximity under the sizing, then
by applying the number 2 to num of cells across proximity gives two layers
to capture the stress detail in the solid.
Automatic feature for Selections you don’t name will inflate the unnamed surfaces, these are usually walls of the tubing, and tetra hedral mesh with boundary layer inflation, the power of this that for smaller ducts it will have a smaller inflation than for the larger ones. Multiple meshing methods used at the same time can be implemented, a smooth transition from hexahedral to tetra hedral.
Therefore in the sizing section it is necessary to select proximity and curvature, also remember to name the inflow and outflow surfaces and then apply to them some inflation, in order to remember which surfaces you want to apply to them the inflation you can call the surfaces inflation 1 , inflation 2, ....etc. The use of the statistical tools can also be beneficial for the user to assess how much he deducts from computational time when he removes unnecessary detail to the models such as fillets and chamfers.

Working with Named Selections
Working with named selections is something you need to master.
Automatic Meshing
The first selection that comes to mind is automatic meshing option.
