The paper refutes the model and claims published in the Solid State Communications [1] as well as elsewhere. The theoretical approach proposed in The multicaloric effect in multiferroic materials by Melvin M.~Vopson has a number of inaccuracies and mistakes. The Author of [1] does not pay necessary attention to the range of applicability of the derived equations and confuses the dependent and independent variables. The resulting equations for electrically and magnetically induced multicaloric effects are incorrect and cannot be used for measurement interpretation.
