WebNov 16, 2014 · Rep Power: 12. If you are using a moving reference frame, stationary walls are always stationary relative to the cell zone. If you are specifying zero absolute velocity in Case B, you will get different results. If you specify zero relative velocity with a moving wall, you should get the same as Case A.
