Hello all,
I developed my FSI code based on the FENothing framework used in step-46. Step-46 shows how to identify the interface between the fluid and solid domain. Also it shows how to set constraints on variables and how to assemble terms on the interface. I just used the same logic in my FSI code. In step-46, the interface handling part gets access to the cells, cell->neighbours, neighbour of neighbour and global index of the face grids on the interface. However, things are much different and difficult in parallel mode, as a cell is locally owned but its neighbour may be not (ghost cells). In a ghost cell, values are only readable. Therefore, it seems impossible to set constraints / write values on index of neighbour cells. I have tried many ways to fix this problem but failed. Do you guys have the similiar experience on this problem? If yes, how to fix it? Any suggestion? I appreciate any feedback/help from you.
