You can find the model with small tetrahedral elements. It will look like the figure shown below.Note: While meshing the solid, there is a trade-off you need to consider. If you choose a smaller element with higher nodes you will get better accuracy in your analysis than larger element. However, the time required to solve the model with smaller elements will much greater than with larger element. Hence, based on the accuracy requirement of the study and how critical the component is in terms of the end product, choose the appropriate parameters for the elements and nodes.
