Week 12:Project-1-Meshing of Door Inner Panel Challenge

AIM:

• To perform preprocessing on the given component on given side door [inner panel] plastic component using hypermesh preprocessing software

Follow the Quality Criteria and mesh the following component and assign thickness:

Target Element Length = 4 Units

S.N	Quality Criteria	Value
1	Aspect Ratio	5
2	Skewness	45
3	Warping	15
4	Taper	0.5
5	Min. Length	2 Units
6	Max. Length	6 Units
7	Min angle Quad	45
8	Max angle Quad	135
9	Min angle Tria	20
10	Max angle Tria	120
10	Tria %	10

objective:

• to generate mid surface manually and do geomatric cleanup
• to generate a mesh with proper meshflow on the given component with low tria concentration
• to check element quality with given quality critiria
• to create a diffrent collector and organize the element to that collector and assign a thickness

procedure :

• import the geomatry
• make in topo mode

• in this plastic component thickness is not uniform so we want to extract parts manualy
• initially we extract base plate which has uniform thickness , for that we go to surface edit and select on surface of base plate then select by phase and offset to half of thickness
• after getting the baseplate check any error in geomatry and if any clean it by suitable components
• then inspect and offset each compoents into half of thickness seppratly

• then we want to extract midsurface of ribs
• of that make a midline beltwwen surface of ribs then trim it by trim with line option, then make surface between it by ruled option in surfaces

• if surfaces are not connected to surface use extent options for connectivity
• extract mid surface of remining type ribs on surface by offseting option

• remining holes and bounds are created as per mentioned above

• after extracting mis surface all parts check connectivity of all parts and do nessesary geomatric cleanups
• toggle unwanted lines
• then start meshing from one side
• make cut lines on ribes for getting good quality meshflow
• minimize tria concentration as possible
• when in meshing process always try to use rebuild option mesh for getting good quality mesh
• after using drag tria option make sure to smooth the mesh
• remove warping by translate the deflected node from surface

• after properly meshing all regions check for free edges in edges option and equalnce all and gety connected all nodes
• if any nodes are not connected check it manually and connect those elements
• after checking for edges check for normals in tools normal option
• make all normals in one direction

• then create collector {create new component}
• then create property and give the thickness
• assign property and thickness to collector

result :

• completed meshing of plastic component with propermeshflow as per given parameters
