Simulation Time in restart runs
 
Hi pals! I'm completely new in CFX!

I wonder why the simulation time reported in cfx-post, starts from 0 sec, in restart runs ? how can I calculate total time of simulation when I continue a transient run using previous result?

Thanks for you advice

Hi Elina,

You have to edit the command file and input the initial time as the latest value solved.

I was wondering wether there is an automatic way of doing it. I recall this issue has caused me some confusion (trouble) in the past.

Good luck!

Hello,

Just set the initial time option in the symulation type menu to 'automatic' or 'automatic with value' rather than 'value' and CFX will read the time value from your specified initial conditions file. If you have any time-dependent CEL, these will also use the correct time values.

Note that when you want to change meshes during the simulation, this does not work.

Hope that helps, latslosh.
