Dear All,

I have a spherical domain with transport of dilute species physics. I need to define diffusion coefficient based on the total normal flux at sphere surface. I define D as follow in variables and I have D data as interpolation.

D0=D(C_0-S*t/V*tds.ntflux_c)

c is concentration and t is time variable.
tds.ntflux_c is total normal flux based on predefined variables in the equation view tab.
S and V and C_0 are constant.

But I got the following error.

Undefined variable: comp1.tds.ntflux_c
any help appreciated.

Thanks.
