Week 5 Challenge : Surface wrap on Automotive Assembly
Aim:To check the geometrical errors and perform the surface wrap to the given 3 models after merged.
Hardware Required:Monitor,Keyboard,Mouse and CPU.
Software Required: ANSA v23.0.0 x64bit.
Theory/Description:
- ANSA is an advanced multidisciplinary CAE pre-processing tool that provides all the necessary functionality for full-model build up, from CAD data to ready-to-run solver input file, in a single integrated environment.
- ANSA is the users preference due to its wide range of features and tools that meet their needs. The list of productive and versatile features is long and the alternative tasks and processes to be completed using them are countless.
- In case of Meshing, ANSA has integrated Batch Meshing tool,which leads to controllable and effortless optimal results, for both shell and volume meshing. Following the versatile mesh area idealization, geometry can be meshed according to modeling requirements by cutting edge surface and volume meshing and wrapping algorithms.
A unique mesh generation environment is composed by:
- proprietary shell meshing algorithms
- high performance and quality volume meshing algorithms
- state-of-the-art boundary layers elements deployment
- Hexahedral dominant meshing
- Acoustic Cavity mesher and the straight forward Wrapping tool
- one-step mesh generation on automatically extracted middle surface
- numerous mesh handling functions.
Procedure:
1.Open the ANSA software, then mport the Engine model and check for the topological clean-up on the surface portions.
2.If any single cons are present on the model then solve the problem by checking closely in wireframe mode.
3.Delete all the unnecessary portions from the model such as unwanted rig like structures.
4.For the surface wrap, only need to edit the problems that are present on the surface.
5.After completion the topo clean-up on the surface then fill all the holes present on the surfae of the engine model.
6.Check all the triple cons closely and and delete all the overleft surfaces.
7.After completion of the removing all the errors from the model, then import the Transmisssion model from the files.
8.Check the model for overleft surfaces and delete unwanted surfaces.
9.Remove all single cons from the model if present any by checking the problem closely using wireframe mode.
10.After completion of topological clean-up to thr transmission model, import the gearbox from the files.
11.Check the model for overleft surfaces and delete unwanted surfaces.
12.Remove all single cons from the model if present any by checking the problem closely using wireframe mode.
13.Now import the engine model and merge with the transmission model.
14.After merging the engine model and the tranmission model, merege the gearbox model with the existing merged model.
15.Now check the model closely and close all the holes present on the entire model.
16.After filling all the holes present on the entire model, compress all unwanted PID's in the properties.
17.Open the mesh deck and go to surfaces and choose wrap option.
18.Name the title and choose element size as 3mm and select all PID's present in the model for the surface wrap
19.After completion of surface wrapping, check whether single volume is obtained ornot by isolating both sides up some lengths.
20.Save and close the file.
Precautions:
- Do the topo clean up accuretely for to make surface wrap accuracy.
- Make sure there should not be any geomtrical erros in the model.
- Set the desired target lengths and make sure everything is perfect while meshing.
- Wisely delete the unwanted surfaces that which are not useful for surface wrap.
Result: Checking and solving all geometrical errors and Surface wrapping after merging to a given 3 models is done using the ANSA software.
Conclusion: I learned a lot of things in this week. I almost used the most of the options in topo mode in clearing the errors in a
model. I almost got the grip in making the changes to improve the model.
