** ERROR 221058 ** Node of tetrahedral element has non-positive mobility.
An internal flow computation error has occurred due to highly distorted elements in the mesh, or very high viscosity values at a node due to problems with the viscosity model for the currently selected material.
Remesh the geometry starting from a better quality Dual Domain mesh (less high aspect ratio triangles). Specify a lower allowed aspect ratio in the 3D meshing parameters. Plot and check the viscosity of the currently selected material.
