Are there any theoretical or experimental data about the low-temperature specific heat of paramagnetic solids with dipolar (not exchange) interaction?

The Schottky anomaly is well-studied, but it exists in ideal systems without interactions. What is the dependence of specific heat on temperature, if the spin-spin interaction is significant? I've...

Can the gradient of granular admixture volume fraction be included in user-defined function in ANSYS Fluent?

I need to make a UDF containing follow source term: Q = A(C) / (1 - C) * dC/dz, where C is volume fraction of granular admixture (e.g., sand or clay) and A is some nonlinear function. Is there any...

What is the correct boundary condition at an impermeable wall for porous media flow?

The most common condition I have seen is vanishing of normal component of fluid velocity at the wall. It makes sense, because Darcy's law describes pore-averaged flow, and the fluid moves even...
