Error



Posted 17 years ago by Denim Umeshkumar Anajwala
After discussing this matter at FEFLOW Services we have found the reason of the problem:
Additional to the [i]Power Function ID's [/i]the user has had defined [i]Time Constant Data[/i] too (in the <Assign> Database > Data regionalization dialog).
Therefore, as Time Constant Data were defined, FEFLOW uses these values for the regionalization, not as expected the Power Funtion ID's.

For the boundary conditions you can use Assign - database - Import Time-varying IDs - Head BC - Automatic regionalization.

Peter,
I am facing the problem to assign a time variant seepage boundary condition

I am trying to follow your procedure but it seems that it does not work:

when I use the command:
Assign - database - Import Time-varying IDs

and when I select the *.trp file, I get this error message:
WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: Unknown time-varying function ID 385. Data point will be skipped.

WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: Unknown time-varying function ID 385. Data point will be skipped.
WARNING: There are MORE unknown time-varying functions. Skipping all ...

the same trp file works fine when I import it a a time-constant data file.

PS. As Feflow allows to assign the pressure instead of the head as 1st boundary condition, why isn't possible to assign a power function for the pressure ? I tryied that but the command "pressure" is disabled when I try to use a time-variant function :(
It would be easier to deal with the pressure as it would have a constant value along the seepage face and I shopuld not have to define a different time-variant function for each node.

I understood what was wrong. I have to define a power function for each node I import and in trp file I have to put the ID of the power function for the selected node. By the way this procedure is quite tricky and very hard to set up. As I asked before , is it possible to use the pressure instead?
