Hello,

my code work fine, but when i add this macro of diffusivity, i get this message error, if you have any suggestion or similar error, contact me.
thank you very much
/*-------------------------------------------------------------------------*/
/* Diffusion coefficient for electrons */

DEFINE_DIFFUSIVITY(udf_electrondiffusivity, c, t, i)
{

return (tempe(c,t,Te)[0] + tempe(c,t,Te)[1] );

}

real temph = C_UDSI_G(c,t,Th);
return (temph[0] + temph(c,t,Th)[1] ) ;

}

excuse me the macro is :
DEFINE_DIFFUSIVITY(udf_electrondiffusivity, c, t, i)
{

return (C_UDSI_G(c,t,Te)[0] + C_UDSI_G(c,t,Te)[1] );

}
/*-------------------------------------------------------------------------*/
/* Diffusion coefficient for Heavy species */
/*-------------------------------------------------------------------------*/
DEFINE_DIFFUSIVITY(udf_heavdiffusivity, c, t, i)
{


return (C_UDSI_G[0] + C_UDSI_G(c,t,Th)[1] ) ;

}

What are the scalar quantities Te and Th for which you are computing the gradients?

i try to add two energy equations in my code, one for electron (with Te: electron temperature) and second for heavy species (Th: heavy temperature)
