How can +I use Gmsh's post-processor in this situation? + +Just create one view for each time step: Gmsh can handle an arbitrary +number of views and it can deal with these separate views as +efficiently as with a single multi-time-step view. The only +disadvantage is that the total amount of disk space used is greater +(since the node data is repeated for each time step). + +In practice, depending on the size of the data set, you may want to +store all the views in a single file or create one separate file for +each view, which you can then load selectively (and thus reduce the +memory required for the analysis). In any case you can use +'Tools->Options->Post-processing->View links' to apply options to +multiple views at once, and the up and down arrow keys to loop through +(animate) the views (instead of the left and right arrow keys for +multi-time-step views). + +Also note that if all the views are based on the same grid, Gmsh can +combine the separate views into a multi-time-step view by using the +'View->Combine->Time Steps' menu, or by using the '-combine' command +line option.
