Reply To: Help: How to link the primary and auxiliary fluid cell in non-equibrilium model?

Hello Rob,

The code can not run and the fluent crashed with error "999999: mpt_accept: error: accept failed : No such file or directory". My UDF was following:

DEFINE_SOURCE(Solid_source,c,t,dS,eqn) 

{

    real Tf, Ts;

    real hfs = HFS_CONSTANT;  // Placeholder value for heat transfer coefficient

    real Afs = AFS_CONSTANT;    // Placeholder value for interfacial area density

    real source;

    const char sv_t;

 

    // Obtain fluid and solid temperatures

    Ts = C_T(c, t);  // 

    Tf =  C_DHX_NBR_T(c,t); 

 

    // Calculate the source term based on the modified expression

    source = hfs * Afs * (pow(Tf, 4.0) - pow(Ts, 4.0));

 

    // Set the derivative of the source term with respect to Tf

    dS[eqn] = - 4.0 * hfs * Afs * pow(Ts, 3.0);

    return source;

}

The maro "C_DHX_NBR_T(c,t)" is in the header file "dual_cell.h". But the fluent also crashed with the same error. I am not sure if it is able to modify the energy source of the non-equibrilium model. The error "999999" always occurred.
