+
+- [ ] Investigate how curvature is computed by interIsoFoam (immiscibleIncompressibleTwoPhaseMixture class): document this in the preprint. 
+
+- [ ] Literature survey on interIsoFoam/interFoam wetting validation - which cases have been used? 
+
+- [ ] interIsoFoam is currently using the *sharp* $`\alpha`$ field - can we simply use Ubbink's laplace smoothing for the $`p-\mathbf{v}`$ coupling?
+
+```
+alphaOld == alpha
+
+solve for alpha
+
+// smoothN is an option read from the fvSolution / alpha
+for (int nSmooth = 0; nSmooth < smoothN ; ++nSmooth);
+{
+    alpha == fvc::average(alpha); // check fvc::average and compare to what Ubbink did
+}
+
+// smoothed alpha goes into p-v coupling, giving a smooth curvature field
+
+pEqn: alpha
+UEqn: alpha
+
+alpha == alphaOld
+```
+
+- [ ] Read about the semi-implicit surface-tension force model - can this help us with parasitic currents?
