This might be an unusual question; I haven't found anything like this in the ANSYS archives, so bear with me, =)
I'm on ANSYS 2020R1, student edition.
Let's say I have a block suspended upright in a static pool of liquid, and I want to see how the fluid moves starting from rest as I move my block straight up and out of the pool.
Let's pretend my block has a 10x10 mm square at its bottom face, and starts fully submerged. But, let's say my block is changing shape as I move! Now, let's pretend that at the bottom of the submerged face of the block, a 1 mm diameter mini cylinder is tacked onto the end of my original block, and a new 1 mm diameter mini cylinder continues to be tacked onto the end at some periodic time interval.
I can imagine the UDF's required to make the block move, and I might have to use VOF methods for the fluid motion (which I'm still looking into), but I haven't figured out a way to 'add new shapes to existing geometry' with ANSYS. Any ideas from the more knowledgeable crowd?
