You will have to be more specific.

How did you generate this ?  
What is incorrect about it ?  
What are you expecting to see ?

Please include screenshots.

i will couple 2 simulator base on matlab and open source code, my simulator use structured grid assume i choose cell no 105 consist of pressure and temperature.

that is input file from OGS but he read my number cell is 504. by using reflection hope my case will solved. but i am realize that my VTU is problem, so the number of cell not in order.

my purpose is if i define cell number 105 in structure grid is same in unstructured grid
