Dear experts,

I need to add multiple data columns to an existing .VTU file. I have a .dat file that includes 200 columns and 1000 rows, and I need to add them the existing VTU file with 200 names like sp1, sp2,…sp200.
I do not know how to using a loop for the 200 columns and add them with sequence name.

This part of my code that I could not complete:

##################################################
meshNew = dsa.WrapDataObject(mesh)
Data = pd.read_table("file.dat", header =None)
Array = np.array(Data)
meshNew.CellData.append(Array, "..names...")
################################################

Thanks,

Your tables are not named, you should name them yourself.

names in the following line is to add heading to the column, but I failed to add all columns once. I used the mentioned code to add only one column and name it, but I could not do the same for all columns
meshNew.CellData.append(Array, “…names…”)
