Hi Jan,

thank you for reply. I modified code:

State*            state = b->state.get();
		CpmMat* mat = dynamic_cast<CpmMat*>(b->material.get());
		const Body::id_t& id    = b->getId();
		Vector3r          f     = Vector3r::Zero();
		Vector3r          m     = Vector3r::Zero();
		state->oldTemp = state->temp;
		state->Cp = mat->CP1 + mat->CP2 * state->oldTemp + mat->CP3 * pow(state->oldTemp,2);
		state->k = mat->K1 + mat->K2 * state->oldTemp + mat->K3 * pow(state->oldTemp, 2) + mat->K4 * pow(state->oldTemp, 3);

But now I get those messages:

How to declare the CpmMat in NewtonIntegrator?
