I defined a constant density for mixture material by UDF as follow, but there are some errors information as following. Do you know what is problem? Thanks.

DEFINE_PROPERTY(cell_density,c,t) {

real den;

den=2967.7679;

return den; } cc: "den.c", line 4: error 1000: Unexpected symbol: "den". cc: "den.c", line 4: error 1588: "real" undefined. cc: "den.c", line 5: error 1588: "den" undefined. *** Error exit code 1

Just change the name of the variable den to something different, like "rho_mix", or easier, write the function as follow:


DEFINE_PROPERTY(cell_density,c,t)
{
return(2967.7679);
}

From the error message, it seems that the internal compiler of FLUENT has some problem to manage the symbol you have choosen for the variable.
