How to restart a 2d Transient analysis of Fluid in a pipe.

[vinny31]

Hi
I am having a small problem restarting a fluidic analysis.
Basically I want to restart a transient fluid analysis. However when I do the restart I was to create a new *.db and continuing the analysis in this new database from the previous time step but write the remaining result to the new corresponding *.rfl file.

For example I have successfully run a Fluid1.db analysis file to 6 us. I now wish to call this file a new name for example Fluid2.db and continue the analysis in this new database from this 6us time step up to 20us. However I wish to write the remaining 14us to the new corresponding Fluid2.rfl file. This is the problem I am having. How do I do this??

Please see the restart file I have below which works fine if I am staying the same Fluid 1 database.

Can anyone suggest how to improve this file.??
