Dear users,
I am trying to simulate a two-phase Darcy flow. But, I end up getting an error as follows:
-Expression d(comp1.c1.t)

I believe c1 is the fluid content which is supposed to change with time. But, I can't figure out how to fix it.
I'd appreciate any advice.
Thanks

I have also the same problem !

Replacing d(comp1.c1,t) by d(comp1.c1,TIME) is recommendation by others but I can not find where to do that.

Hope to hear from others soon !
