Using libMesh to track a cloud of points with degrees of freedom but without connectivity wouldn't be too hard; you'd just create a NodeElem for each point. Alternatively, you could keep some control of topology by connecting nearby Nodes with Edge2 elements, and this would let libMesh auto-construct the correct matrix sparsity pattern too. Building the correct stencils and finding node neighbors to construct those edges would be all up to you; I don't think any libMesh utilities will be much help. Even our PointLocator classes are mostly designed to find points in meshes, not in free space. --- Roy ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
