This article is for FE beginners. In this article, I am going to share one case study where I meshed a model with mesh type and sizes. We are going to see how a hex dominant mesh can help a FE engineer to reduce the required computation resources.
The animation above shows the CAD model considered the discussion of case study mentioned in this article.
This model was meshed using ANSYS Workbench. Three mesh methods were followed as:
Challenges in Hex meshing
Hex meshing is always preferred but it is not possible to perform if the shape of the model is too complex. But, in case you still want to go with HEX meshing, you need to do geometrical simplification. With this I mean to say that you need to divide/slice you model into simple shape. Just take a loop how I achieved hex meshing for the model above. If you need a video tutorial, ping me I will get back to you.
Other results of meshing are shown below:
Voila! A clear cut 55.2% reduction in mesh size. This means that you are going to save both computation resources and simulation time.

Wait! but what about results!
Don't worry, showing results without discussing about boundary conditions has no meaning. So, lets first see what are the boundary conditions
Oh! Load and displacement, which means structural simulation. Now you expect the outcomes, displacement and stress.
Conclusions:
I hope this will help you to understand
