Meshing in HyperMesh - Car body Mesh Part - 1

This is 1st video tutorial for car meshing. I tried to explain how to make structured mesh for different body part of vehicle.

Awesome video, Excellent explanation... keep making videos

[@simtech0598]

Thanks for appreciation. I'll try to make new video soon.

[@shivaforirctc272]

Really helpful video, Thank you

[@chandunaidu4693]

very nice

[@JayaPrakash-zx4cp]

Sir please make a video for plastic components middlesurface extraction and meshing techniques... please sir

[@simtech0598]

Dear, 1. I'll upload mid-surface extraction video soon in Hypermesh. 2. In Hypermesh there is no separate options for Plastic mesh, we can do plastic meshing by same options i explained.

[@engrshairkhan]

very nice ..!

[@kalpak1000]

Very Helpful information sir, can you please provide this model for practices

[@simtech0598]

Plz find model in Hypermesh Folder - drive.google.com/folderview?id=1Sbcv6kPcvTAvEM1EK2JhRMIHskCbcebW

Sir, what is the affect on geometry when we toggle the edge? Doesn't our geometry got damaged.?

[@simtech0598]

Dear, It depends on the tolerence value. If tolerence is huge... geometry may change...if tolerence is very less ..change in geometry also negligible.

[@aniketpatil3484]

Please make videos on plastic components meshing, and 3d meshing...also please video on connector....it's request

[@simtech0598]

In plastic meshing also same option has to be utilise for meshing. One can do plastic meshing if understood these options properly.

[@aniketpatil3484]

Ok sir, but for variable thickeness, there are different techniques so I want to learn that one

[@aniketpatil3484]

@@simtech0598 I want to know that, in the industry, is it using same technique for 2d meshing?

Hi sir, for you what is the best way to détermine the mesh size element ?

[@simtech0598]

Dear, There is not a single rule. Dependent on area of interest, minimum feature size, type of analysis, available computational power and project time. Like for static analysis and implicit dynamic - minimum size not affect simulation time...only your bound will be total number of elements/nodes But for explicit dynamic minimum size od element decides stable time increment hence we try to keep minimum size of element as max as possible..but at same time it also capture geometric feature.

[@maheshtirumareddy4120]

sir, can you tell me when we can use mixed element type as you created mesh with only quad elements ? some of the elements very less size is it ok for the mesh criteria ?

[@simtech0598]

Dear, For structural analysis generally quad element preferable, its not mean always keep zero tria...it means try to minimize tria within 5% (depend on mesh size, analysis accuracy and other factors).. important is - tria should not on stress concentration region. Mix mesh more preferable ko keep better mesh flow .. generally required for wave propagation (dynamic analysis) type of event... crash, drop etc. Here the car body mesh is for practice purpose...how one can split and minimise tria..! For structural analysis minimum element size not matter at all..so you can keep sufficient enough small size element...but for dynamic explicit one carefully need to manage minimum size.. as large as possible...bcz minimum size of element decide step time taken by solver..hence whole analysis time depends on minimum size element.

Hello, can you please name the model of car plase? i want to make a crash analysis for this car and check results from ncap results

[@simtech0598]

Dear, No standard model, Just trial. This model don't have chassis..so crash analysis is meaningless.

Sir please do videos for contacts ?

It will take time..in between number of topics need to cover.
