Week 6- Challenge

Objective: To clean up the given geometry using different options like quick edit panel and obtaining the given criteria.

Procedure:

• Open HyperWorks start importing the model from your saved files.
• After opening the model try to give a glance and understands the model, there are 5 sub-models given 1 latch, 2 hinges, 1 outer layer, 1 inner layer.ize
• While opening HyperWorks we need to select the model type as a STEP file and import the geometry.
• Then after importing the geometry, we need to make the first step as extracting the mid surface for the given model.
• Now we have the mid surface, we need to hide the outer part of the geometry to see the mid surface clearly.
• Later on, we will use a quick edit option which we see it in geometry, using this where we have circle in an open surface we will give a washer split so that it gets a complete mesh.
• The next process will be selecting 2-D, in this select automesh option and selecting the surfaces we need to automesh the entire component once using the mixed option and giving element size as 5mm.
• after meshing we need to check whether we have fewer trias and less rotational quads, we can eliminate them by re-meshing the particular surface.
• so we need to repeat the same process for the laches and hinges but in the case of outer and inner layers, there would be a problem of not taking the complete body to mesh therefore we need to use quick edit option we need to split the surface using this by node-to-node or node to line then we need to mesh.
• after that we need to check for the quality criteria as given by using f10 key we can select options for checking the quality criteria of the preferred elements. while checking each criteria when the elements don't match then we need to mask the given elements save then, later on, we need to edit then by splitting the quads or mixing the tria elements.
• By selecting mask option and saving them they will highlight only the elements which don't match the quality criteria.
• we have an option called as smooth in the 2-D option by selecting this every element will become smooth by aligning clean. As long as the smooth option gets 0 value we need to smooth the given mesh.
• later on after all this we need to use the option named element to clean up, by this it cleans all the elements which don't resist its position.
• after meeting all the required criteria now we finished our model.

Conclusion: Thus we obtain clean geometry by using different quality criteria available in the tool. you can observe it in the below zip file folder.
