Week_8_Plastic Model_1

OBJECTIVE:- To obtain the midsurface of the given component and mesh it with the given quality criteria.

GIVEN MODEL:-

PROCEDURE:-

  • As a first step, We are going to import the model & then visualize it. So, as can see in the image, its looks like a solid body. So, Using a 'delete' command deleted it.

  • Now, I need to check whether there is a geometry defect or not. So, to check easily I changed its colour to 2D topo mode and wireframe geometry selected .

MID-SURFACE GENERATION:-

  • After this we need to generate a mid-surface, so for that we have to choose a suitable method to generate mid-surface. So, as per the measurement of the model at the boundary of the model around 3 & 3.5 mm achieved, and at the rib & stiffener location I got 1.5 & 2 mm respectively. So, in conclusion it looks like a plastic component.
  • So, there are three option for mid-surface generation. 'offset+planes+sweeps', 'offset-planes', offset.
  • So, I tried the first 2 options & from the result, I will go with the 1st option. Because there is not much difference between. Can see the generated mid-surfaces as per below image.

TOPO CLEANUP IN MID-SURFACE:-

  • After this, it required a topo cleanup. As per the min/max size(3/7) value some cons are suppressed and at the fillet location to capture the geometry and to avoid an element failure, some cons are created, can be seen in the below image.

MESH GENERATION:-

  • Now, it's time to generate a mesh, So, according to geometry I decided to generate a mesh of below area first then other.

  • As you can see the mesh is generated using 'automesh' command, But only by one click it's not generating a perfect mesh, using a 'rebuild mesh', 'elem cleanup', 'quality index', 'translate', etc. commands are used to correct them.

RESULTS:

  • Midsurface has been obtained and mesh has been generated for the plastic model. The thickness is also assigned to the model.

CONCLUSION:

  • Mid-surface is extracted from the provided Plastic model, and mesh is created in accordance with the provided quality criteria. final result obtain is error free.
