OK, I modified my original codes by commenting the assignment of nelx,nely,nelz, and run the codes with the latest Nek5000 on github.<br>
Now the call quickmv works, but after a few steps the run stoped with error of:<br>

I am not sure what have been changed for the moving-mesh modelling in the latest Nek5000.<br>
My codes works very well with the old Nek5000.<br>
<br>
Thanks,<br>
