This video explains an advanced technique that is very helpful to enhance computational time without losing model accuracy. The method is useful for 3D models with critical areas such as models with contact. The technique needs partitioning the face then using cell partitioning to divide the part into more components. Next by using the sweep technique the element size would increase in X, Y, and Z directions. This is a very beneficial technique to use small element sizes for the areas with a high-stress gradient and the larger elements for the far region. To have a better understanding of the procedure, the sweep profile and sweep path are explained in a PowerPoint slide. The element size is a key factor in large simulations as doubling element size would lead to reducing the computational time to 1/8 for standard models. This ratio will be larger for explicit models as it affects the incerement time as well. To learn more you could watch this series of videos about explicit models. 1:   • How to decrease processing time for e...   2:   • How to decrease processing time for e...   3:   • How to decrease processing time for e...   4:   • How to decrease processing time for e...   When it comes to biomechanical models the story is different. Since the geometries are complex it is very important to define very fine element sizes for contact regions. for the contact areas, we need to make sure we are using the right ratio for the master and slave elements. Otherwise, we will face errors as was explained in this video:    • How to Fix Errors in Abaqus by Modify...   There are many techniques to increase element size for the far region to save time. Each is useful and we will cover them one by one. in these series of videos.
