Project 2 - 2D meshing on the instrumental Panel
2D meshing on dashboard compoenent
Aim: To create a mid surface and mesh is done by casting with the given quality criteria and to make sure the element given is free from geometrical errors.
Objective: To perform the geometry cleanup and create a 2-D mesh in the Dashboard/IP substrate model with the given element quality criteria. After meshing the component has to be assigned with a thickness.
Quality criteria:
| S.No | Quality Criteria | Value |
| 1 | Target/Average length | 4 |
| 2 | Minimum Length | 2 |
| 3 | Maximum Length | 6 |
| 4 | Aspect | 3 |
| 5 | Warpage | 15 |
| 6 | Skewness | 45 |
| 7 | Jacobian | 0.7 |
| 8 | Minimum Quad Angle | 45 |
| 9 | Maximum Quad Angle | 135 |
| 10 | Minimum Tria Angle | 30 |
| 11 | Maximum Tria Angle | 120 |
| 12 | Tria Percentage | 15 |
Procedure:
1. Importoing the CAD model from the from the desktop page as follow:
Import the model from the file option bar -->new-->select the file from the particular location.
We must "prepare" the component in order to make the meshing process easier. This model needs to be topologically cleaned up. before we can utilise the topo tool from Faces > Topo in the topo deck. We can move forward after highlighting the entire component with the tool active. Due to the fact that it is meant to be a closed volume, this corrects all single cons, which are now accurately represented as double cons.
2. after importing the CAD model, first and for most need to check the material. This is done to check the whether the material is defined to model or not. This is done to check whether the material is defined to model or not.
In the similar way find any error in geometry of the particular model as follow. There get a few geometry error, which is need to be fix. The geometry occurs due to cons in structure it may be single cons and triple cons. There are some open surfaces that are generating single cons and it is filled by building surfaces in FACES option.
3. To access to the casting mesh. On the topo deck, select Faces > Mid. Surface > Casting to go to the casting tool. The casting algorithm then takes over after the information marked in the following snapshot is entered and entered. It takes some time to complete.
As we can see, there are a number of pieces that don't meet the required standards for quality, and the mesh flow isn't all that nice, save for some specific areas.
The casting algorithm appeared to be inaccurate in many areas, particularly when it came to hole captures and cuts.
Final model:
The Casting was done on the given models and meshed as per the mesh parameters and quality criteria. The number of trias and the failed elements is maintained at a minimum. The models are attached in the below links.
