What is LATONA_CASIA?
Aim
Ver3.0 uses the initial mid-mesh function provided by HyperWorks (Altair Engineering) or ANSA (BETA CAE Systems) and automatically generate the final high-quality mid-mesh result. This can be used for assy model with a few tens of parts.
Advantages of LATONA_CASIA
- Always give the same output result no matter who use it
- Good geometrical tracking ability
- Reduce manual work (final result has mesh quality error of about 1 - 2%)
Features
Functions List
- Auto repair of the input CAD model
- High-quality mid-mesh generation
- Auto repair for imperfect/erroneous mid-mesh
- Pre-registration method for complicated shapes (customization is possible to add new shapes)
- Customization: automatic process for boundary condition setting using Artificial Intelligence (AI)
Embedded Function
Flow of mesh generation process
About overall functions
It is as easy as just inputing the CAD geometry model into Graphical User Interface (GUI) and all the process will run automatically
Auto repair function for input CAD model
- Auto-repair for erroneous input CAD model
- Surface cracks: stitch
- Surface loss: fill with new surface
- Unnecessary surface: delete duplicate, unconnected surfaces, and unwanted surfaces (in connection with mid-mesh generation)
Option to retrieve mid-mesh generation result data
- Please select any software in use to obtain initial mid-mesh data, considering which one will give better tracking of mid-mesh result
- Select initial mid-mesh generation software: HyperWorks or ANSA
- Specify all the necessary parameters (mesh size, etc.) in parameter file
Execution of a few tens of models is possible (order of execution is determined by the order of model registration into GUI)
- As simple as drag&drop the input CAD model into the GUI and click on "Run" button. After that, this software will run automatically
- Execution status can be monitored through the GUI progress bar
Generation of high-quality mid-mesh for complicated shapes through pre-registration of any designated shapes
- Pre-registered basic shapes
- Addition of new shape by customization
Function to improve/fix mesh quality error
- Control of mesh division number to avoid min length error
- For optimization of mesh quality error while keeping the geometry shape, mesh size of equal length is created at the boundary edges
Wall thickness measurement function
- Thickness is measured for each component/PID
Miscellaneous
Analysis-ready mid-mesh model
LATONA_CASIA will fix the mesh quality error such as warpage, skew, max angle, etc. and give output of mesh result that is analysis ready for eigenvalue analysis (Optistruct.)
Type of analysis that is covered:
- Sparse-Matrix Solver
- Direct Method
- Block Lanczos Eigenvalue Extraction
Way of operating
Inside LATONA_CASIA GUI, it takes only 3 steps to obtain the output mid-mesh result automatically
Procedure
Prepare 3 files as below
Option setting for choosing software in use to obtain initial mid-mesh data can be found inside parameter file
Insert/register CAD model into GUI
Set the necessary parameters and start execution
Parameter option to select which software in use to generate initial mid-mesh
- Select software name from parameter file
- From GUI of LATONA_CASIA, set the required parameters related to the selected software in ①
