Issue when IBM body moves from one processor core to other

[Akarshr1234]

Hi,
I have to assign some motion in y to a flexible filament, and the
filament's x position has to be determined dynamically. Everything works
fine, but as filament enters another processor, the simulation hangs up
and doesn't proceed further.
Here is the simulation result:-

result_0.mp4

The video contains the Ux field, and the picture consists of the Mpiblock
number.
Currently, I am dividing the domain into two parts in the x-direction.
I am using filament as an IBM body.
I am simulating LINUX-UBUNTU 20.04.

In issue#9 you had talked about a
partial solution. So, can you tell me what I should do to avoid the
hanging of simulation when the body moves from one proc to another?

I also like to add that when I start the simulation at the position where
the body lies on the boundary of the two procs, it gives me a segmentation
fault.

I hope you will reply to me at my earliest convenience.

Thank You.
