Inlet setting of k epsilon with velocity profile OpenFOAM

romney · July 13, 2022, 23:54

Hi,

I use the RANS k-epsilon model to simulate the wind field.
The velocity of the inflow uses the velocity profile by csv file.
k epsilon depends on speed, I also set k epsilon profile by csv file as inflow,
but it's failed.

This is an error message and setting file:
setting&error message.zip

Thanks

Have you tried commenting out (//):
#includeEtc "caseDicts/setConstraintTypes"
? Since I saw you do not have it for U
Cheers

Hi,
al.csc

Thanks for your response.
I already commented out it.

There should be no problem with U(i guess?)
because the error message appears when k is calculated...?

I meant in k

I commented out this in k & epsilon also
#includeEtc "caseDicts/setConstraintTypes"

the error message is still the same...
