UDF{ C_VOF(c,pt[n]) } two phase flow

Hi all; I want to add mass sources to the mass equation of each phase of a multiphase flow(VOF), to model the mass transfer between the phases. My source terms contain the volume fraction of one of the phases. Therefore I have to use the multiphase macro ( C_VOF(c,pt[n]) ). When I written my UDF , during the initialization in Fluent, I encountered to an error : FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: ()
I think that I must use subdomain,subthread,getdomain,...etc. !? Please someone guide me . Thanks. |

<font face = "courier new">This error could come coz of many reasons:
(1) When u try to use a variable which is yet not allocated. (2) When u recompile your UDF code without restarting fluent (3) When u try to access a variable which is not permitted to be accessed. Check your code for these Murali</font> |

Hi; I think that this error appears from the using of the macro C_VOF(c,pt[n]).Because when I use this macro,this error appears and when I change this macro to the another macro,I have not any errors. do you have any informations about the using of this macro ? thanks.
