Table xyz,t

mesut · May 23, 2017, 17:39

I'm working on a compressible flow problem.
Firstly, i'm very new at CFD.
I should apply time dependent velocity in inlet. I searched some topics about this and i see that i should use table xyz,t. Is this correct or not? If it's correct, i created a table for just trying this method but i have some errors when i start to run. "non-existent column "null""

where is my fault?

I'm sorry if this question is nonsense

I hope you can help me.

If you have that error then your boundary condition is missing a specification. You set the BC to be the table, but you didn't tell STAR-CCM+ which column is what data. Go back and look at your BC

Thank you for your answer.

I applied velocity inlet and under the velocity properties, i choosed table xyz,time. Under the table option, i chose my table but i couldn't set table: X-data , Y-data and Z-data. Because none available is written there.

Probably this problem isn't hard to solve but i don't know this program well. Maybe i did some mistakes in other parts. Though i checked my table, i didn't see any problem but i'm confused. I also could not find this method in detail in the user guide.

If you imported the csv data from somewhere, maybe the format of the table is not correct

Thank you,

I think you are right,probably i did some mistakes about format of the table.

I have the same error but yet could resolve this error.

please share your experience.
