How to add a UDF to a compiled UDF library

Hi,
I want to know if it is possible to add own UDF to a exist compiled UDF library which has no source code. For example, FLUENT6.1 has provided MHD module that is a kind of UDF. In this library, the UDF, mhd_dpm_force, has been provided as the body force of the particle in the electromagnetic filed. However, I want to use some coefficient, say co0, to multiple this body force as: co0*mhd_dpm_force. I can use UDF to define some function. However, How can I combine the UDF defined by me to the MHD module which is provided FLUENT as UDF. Of course, FLUENT does not provide any source file of UDF about MHD. I cheked the MHD1.0 under addons fold of Fluent.Inc and found there are some libudf.so file. If these files are object files, it may be possible to re-compile my source code with those object file. Is it right ? Does any body has such kind of expereince? My OS is LINUX red hat. Thanks. KIM |

Hi KIM,
I also shared the similar experience with you, and I want to amend the libudf.dll (in Windows), but I found it's too difficlut to so do. |

Hi every one.
I want to define a boundary condition of a MHD problem by use of UDF. In the section UDS of the boundary I select the specified flux for the boundary and then in user-Define Scalar Boundary Value I select the udf which was interpreted. When I start the iteration following error is appeared! Error: phi_boundary: Invalid electric potential field boundary Error Object: () In the UDF as u see I write a simple commend: #include "udf.h" DEFINE_PROFILE(Electrical_Potential,t,i) { face_t f; begin_f_loop(f,t) { F_UDSI(f,t,0)=10; } end_f_loop(f,t) } Thanks in advance. |
