Can anyone help me running my code in your computer and see if it works?

My code is kind of long, I'm now having errors both interpreting and compiling the UDF into my model.

I've ever successfully compiling this code in Fluent 17.0, but now my lab updated the whole system and installed Fluent 18.0 instead of 17.0. Then the error comes to be:

Error: The UDF library you are trying to load (D:\2017fall\2017fall_files\dp0\FFF-1\Fluent\libudf) is not compiled for 2d on the current platform (win64).\n\nThe system cannot find the file specified.
\n\nD:\2017fall\2017fall_files\dp0\FFF-1\Fluent\D:\2017fall\2017fall_files\dp0\FFF-1\Fluent\libudf\win64\2d\libudf.dll
Error Object: #f

I then tried to interpret the code, I got the error:

Error: received a fatal signal (Segmentation fault).
Error Object: #f

When I interpreted the code in Fluent 17.0, I got the same error, I searched the forum and someone suggested me compiling instead of interpreting, it worked! But after the lab updated the windows system and got 18.0, I got error as I posted above. I'm wondering if the error is caused by some bug in my code or it's caused by the something else.

My code is as below:

M4_integ_minus=-De*rhog*C_T_G(c0,t0)[0]*(zt2-(y+h0))*dx;

C_UDMI(c0,t0,0)=patm-2*sigma/r+(rho*g-mu/kapa*(a0-2*Ht*b0)/(2*Ht*b)*(h2-h1)/dt)*(zt2-(y+h0))-mu/kapa/rho/Ht*((zt2-(y+h0))*M3_integ+M4_integ);


}

h1=h2;
zt1=zt2;
weight_loss=weight_loss_add+M1_integ*2*b*1000*dt;

}



Any help would be appreciated. Thanks a lot in advance.

Did you successfully compiled your code for 18 version?

Check you windows environment variable for fluent. may be it still uses path to 17 version. Fluent_inc is important
