Hello,

I want to add a saturated ammonia table (Temp vs Pressure) for evaporation-condensation of ammonia. 

As per guidance from ANSYS help , image attached below, i tried to input a table in ansys fluent

The below image shows my input in ANSYS Fluent > User defined > read table > table file manager > read . 

I tried multiple ways to input this data, check the directory name, i am getting below mentioned three errors for different variation but the table is not loading in ansys.

 

Please guide me in this matter.

What does you data look like in WordPad? Are there any white space characters in the file?

Dear Rob, 

It have put my data in excel and then read the table in ANSYS.

But now, i just put my data in wordpad. below is the image.

There is no spaces before and after Psat or Tsat etc. but one error i recieved is ",invalid column Psat"

 

Other errors are "EOF in string read" etc. 

You can see the errors in above post. there are total three different errors i recieved when i read tables with different setting.

Yes, write out csv and see it that works. It's very easy to get white space characters that confuse the Fluent data readers.

Hi, 

There are multiple csv formats here i found while converting .xlsx (excel) format. 

.CSV UTF-8 (Comma delimited)

.CSV (Comma delimited)

.CSV (Macintosh)

.CSV (MS-DOS)

i tried all these formats and i am getting this error in console. 

 

 

[Rob]

Pick one with no white space characters and no commas. 

[abdullahhassan]

Yes, I have converted my excel .xlsx format into .csv (comma delimited). 

.csv format is the one in which spaces are converted into commas.  

But still i am getting this issue. 

Can you help me with this. 

[Rob]

What is different between your table and the example in the manual? 

If you manually type in a few rows of data does that work? 

[abdullahhassan]

I am just using saturation ammonia table. The table format is same, I follow the instructions online. 

Maybe there is some issue while converting .xlsx file into .csv .

I tried converting .xlsx format into .csv ONLINE this time. 

Luckily, after reading the file into ANSYS, it is showing now (as shown below), previously, i was unlucky in this.

 

but still i get this error.

The error means there's missing setting, basically you have a blank field somewhere. So, now the table reads in OK look through the rest of the set up.

Thank you so much Rob for your help.

The issue is resolved. as you said before, tried to open the file in wordpad. I opened it and saved the file in .txt format. then i read the table in ANSYS and it works fine.
