Detailed Description

Reconstructs a mixture's cell scalars (mass fractions and the thermodynamic surrogates gamma, e0) with the face reconstruction that the flow block uses:

• first order;
• MUSCL: least-squares gradients and one limiter value per cell, the minimum over all scalars of the flow block's limiter type, further reduced so that every mass fraction stays in [0, 1] and gamma above 1 at every face;
• TENO: the flow block's linear weights (TENOScalarValues) with one bound-preserving factor theta per cell (Zhang & Shu 2010), the largest in [0, 1] keeping every Y_k in [0, 1] and gamma above 1 at every face point, and in troubled cells every scalar within the range of the cell and its face neighbors.

Member Function Documentation

calc()

void ScalarReconstruction::calc	(	ScalarView	scalars,
		Kokkos::View< rtype *[N_CONSERVATIVE]>	W,
		Kokkos::View< rtype **[2][2]>	face_thermo
	)

After the flow block's reconstruction: what the scalars need beyond it (MUSCL gradients and limiters, TENO factors theta), and the face values of [gamma, e0] on both sides of every face, written to face_thermo(face, q, side, 0/1).

Parameters

W	Cell states W = [rho, u, p], for the limiter thresholds.
