I am getting error when trying to react gypsum with biomass (ultimate) in a Gibbs reactor.

ERROR

RGIBBS DID NOT CONVERGE. MAXIMUM ITERATIONS EXCEEDED

You could try just increasing number of iterations, if you haven't already, otherwise one workaround is to use an RStoich reactor and put the products into an RGibbs, which in principle should get to the same equilibrium.
