3 Dimensional User Function
 

Dear All,

I am trying to import 3 dimensional data into user function in CFX-Pre.

my data is like below:
X,Y,Z,Velocity
1,2,4,0.2
.....

I got the following error after importing data.

ERROR
Incorrect number of arguments specified in CEL FUNCTION 'Function 1'.
Expected number: 3; actual: 1.

Please let me know where the problem is from.

Thank you.
Kind regards,
AshtonJ

Make sure the header in the file is in a format similar to this:

Thank you.

I arranged the data in following format.

[Name]
VelocityMag
[Spatial Fields]
x,y,z
[Data]
1,2,2,0.2

Then, I tried to import the data into User function with three dimensional option. It gave the following error:

3 Data item() could not be read as a number.

Please help me to fix this.

Thank you.
Kind regards,
ashkan

You misunderstood, make sure the header is in the format I suggested. Then your file would look something like:

3 Dimensional User Function
 

Sorry for bumping a 3 years old thread, I arranged a 3d data in following format(as Mr. lance suggested):

[Name]
myname
[Spatial Fields]
x,y,z
[Data]
x [ m ], y [ m ], z [ m ], Velocity [ m/s ]
1,11,12,20
12,11,12,20
15,13,14,18

but it gave the following error:

"1 Data item() could not be read as a number."

then I decided to define it without importing data as shown in the attached image,

but then it gave the following error:


"ERROR
Incorrect number of arguments specified in CEL FUNCTION 'Function 1'.
Expected number: 3; actual: 1."


Please help me to fix this.:confused:

Before you accuse CFX of having a bug - have you done the basic checks?

Have you checked your carriage returns are correct (Linux versus Windows)?
Have you confirmed that there is a carriage return after the last line?
Have you tried it with another data set?

Hi Mr. Horrocks,
Thanks for your attention; I really appreciate your help.

just now i have solved my problem,:o
there were two mistakes in my previous work:
1- Imported text file should not have any header.
2- I should define units for every argument (m, m, m) in "Argument units field"


best regards,
