I have two solid geometries intersecting each other (a cuboid and a cylinder). I have developed independent meshes in LS Dyna. Now I want to combine the meshes in one. Please help.
This is an important question.
A path leading to an answer to this question entails a sequence of mappings and pullbacks from one mesh to another one. See, for example, the attached image from
Michel Bercovier ∗and Ilya Soloveichik

More to the point, see

See, for example, Fig. 1.1 on page 2, showing meshes that move and intersect.
Here is another step towards a solution to the problem of capturing the intersection of multiples meshes:

Sample geometry of the intersection of superimposed meshes is shown in the attached image (from p. 3 in the paper). Intersection construction is explained algorithmically on p. 11.
Thank you James F Peters Sir for your insightful guidance based on my problem definition. In addition, I tried welding of one member with the other. In this, I have joined merged nodes of each member which has worked for my problem for designing the frame of a truck. Thank you very much again.
