Time varying write interval in controlDict
 
Dear foam'ers,
does anybody know how to write the requested fields on a varying period of time rather than a constant interval?
I need a higher frequency after a specific time and don't want to get into troubles with my IT admin while overloading the cluster :)
Is there something for
Code:
writeInterval  0.05;
similar to a variable BC?
Code:
Patch1   
{
  type        timeVaryingUniformFixedValue;
  fileName    "fileToBeRead";
  outOfBounds  clamp;
}
Regards,
sabin

This would be very helpful for me aswell.
Does anyone know how to do it?

hello,

If you use the 2.1 version, there is a new control for timing the writing
(see http://www.openfoam.org/version2.1.0...me-control.php)

If you don't use the 2.1 version, you can try changing the parameter manually in controlDict by the time you need the change.

I was running a case and by the end of the run (I checked the log file), I changed the endTime parameter and the case understood my change in controlDict, what made me realize that controlDict is read upon changes in it. So, if you don't mind changing the writeInterval manually, this is one way to make it happen.

Regards,

Paulo
