Hi,

I'm simulating a VIV problem and I am using UDF to prescribe the cylinder movement.
I'm having trouble compiling the UDF. The message ERROR 193 appears. I've done some research here in the forum but still can not solve this problem.


Error: Error code: 193

Error Object: #f

I'm using :
Fluent 16
Win 7 64
Virtual Studio 2015 Express

What can I do?

Thank you very much!

What is your UDF and complete error message?

HI,

My UDF solves the 2D oscillating cylinder.

I resolved my problem, I list below what I did:

First I'm running: Fluent 16, W7 x64.

1) Unistalled some old C++ versions (They appeared in Windows Control Panel);
2) Installed Microsoft Windows SDK v7.0 (available in Microsoft website)
3) Installed Microsoft Visual Studio 2013 (available in Microsoft website)
4) Start Fluent from CMD Shell

Works fine!

As I initially tried to compile my UDF, I got the following error message

"'nmake' is not recognized as an internal or external command, operable program or batch file".

I then installed Microsoft Visual Studio 10. I also followed the remedies given in the 'wiki' page. I opened fluent from the VS Command Prompt and when I tried to compile the udf it got 'built', however when I tried to 'load' the function I got 'Error:193'.

In the wiki page it was written to get 'SDK' for a 64 bit system, however when I open fluent from the SDK 7.1 Command Prompt. I get the initial error "'nmake' is not recognized as an internal or external command, operable program or batch file" once again.

Has someone else faced this problem? ( I am using Ansys 16.1 in Win10 (64 bit)) Please help, its urgent.

Hello
i don't think it is a compiler kind of error (i mean this error is not because of visual studio or ...), so post your udf here maybe we can help you.
i post a udf here try to compile it , if no error happens then your udf is your problem not visual studio. here is the udf:
#include "udf.h"
DEFINE_PROPERTY(density,c,t)
{
real rho;
real temp;
real temp_ref = 303;
temp = C_T(c,t);
rho = 1.225 * (1 - (1./temp_ref) * (temp - temp_ref));
return rho;
}

Hello,

Yeah I am geting the same error, even with this udf.

I think it is a compiler error. More specifically: you don't have a compiler, at least Fluent can not find it.

when I tried to compile the udf it got 'built'

Can you show what happened after you click "build"?

I used ANSYS 17 on windows 10, with Microsoft Visual Studio 2015 Express Edition (the Community Edition does NOT work) and it worked for me.

Best of Luck

Did you change any of your environmental variables?

Repeating the above comment but I can confirm that after a lot of messing around with Ansys 17.2 in Windows 10, I finally eliminated the error 193 message by uninstalling Microsoft Visual Studio Community Edition 2015 and installing Microsoft Visual Studio Express 2013. Abhiroop's solution works for me.

Should have installed 2015 come to think of it but 2013 was just the first one I clicked on and it does the job.

I follow your suggestion, and I succeed! Many thanks!

Yup, this works for me too. Just for everyone's knowledge:

When I installed VS 2013 (since it's compatible with Ansys 19.2), this issue still persisted. So I had to set my environment variables to reference VS2013, uninstalled VS2012 and deleted all the remaining files that aren't automatically deleted in your C:\ drive when uninstalling. I then restarted my computer.

However I then ran into this problem when I tried to load the udf library:

LINK : fatal error LNK1104: cannot open file 'libudf.dll'

All I had to do was close Fluent, delete the udf folder that Fluent creates when it compiles your .c files. Then I reran Fluent. I did all this in batch mode by the way.
