Project 1 - Meshing of Floor Panel

Generating mid surface and mesh after geometry clean-up
of floor panel as per given quality criteria by using ANSA
software.

Objective:
The main aim is to mesh the mid-surface of floor panel with given quality criteria of mesh parameter
using ANSA Software. And to use efficient method to do geometry clean up and get mid surface of
inner panel.
Procedure with CAD model images:
 The given CAD model from Design team.
As shown in figures below the given cad geometry need to do geometry and topology clean up.

Fig. 2: Geometrical distortion.
 After importing .stl file in ANSA, observation found that 53 unchecked areas were present,
where geometry needs to be check for clean-up.
 Start with checking single, double and triple cons. I have used Topo option in faces group to
remove unnecessary single cons, and triple cons are releases using release option in CONS
group.
 In some cases new faces are assigned where faces was missing. (For this new option has
used which is available in faces group as shown in fig. below.)

 To make fine feature areas in a geometry, used fine option available in Auxiliaries group.
 The mid-surface extracted using automatic method to reduce time. The mid-surface option
available in faces group used for extracting mid-surface.

 The separate properties were assigned for extracted mid-surface using set PID option
available which is available in faces group and the thickness is given for the same.

 Before going for meshing check geometry was executed.

 In meshing the given mesh parameter and quality criteria has been set for meshing.

 The meshing started by using face section. Best mesh option used in meshing module for
meshing.
 The reconstruct mesh option used which was available shell mesh Group.
 Cut option used which is available in macros group to compromising feature areas like fillet
to achieve mesh quality criteria and to get meshing done.
 Split and swap options were used which are available in element group for getting better
mesh flow.

Results:
The geometrical clean up, mid-surface extraction and meshing of floor panel successfully
carried out using ANSA Software.
