Dear Mr Nelson, I try to create a quarter of circle at each corner of the square. I was succesful to create the regions at two corner. I apply the same way for other two because they are similar way, but it doesn't work. I am not sure what wrong with that. I can't found any mistake. In the boundaries, I can't make region 6 and 8 work properly. Can you please help me with this. Thank you ( the file is attached)

The mystery is why it ran at all! Your regions 2, 4, etc, are not closed. You need to put in a return arc to close the figure. Or you can use the overlaying character of FlexPDE regions to simply overlay a small quarter-circle on a slightly larger one, as follows: --------------------------------- region 2 START(box,-box) Line to (box, -box+ri) arc(center=box,-box) angle=90 line to close region 3 START(box,-box) Line to (box, -box+rf) arc(center=box,-box) angle=90 line to close ------------------------------- The active region 2 will be the narrow gap between rf and ri. | |||
