Hi,

I have a list of cgns files names as file\_01.cgns, file\_02.cgns, file\_03.cgns etc. It is just time varying grid files. The time variable is not written into it. Is there a way paraview can load it as a group and animate it frame by frame? Right now, when I load the group, all of the grids appear simultaneously. Thanks for your help.
