Dear Wolfgang, Thanks for your answer. To be clearer, Yidong and I have been working on the material point method (MPM) which is an offspring of the particle in cell method. We have implemented in using deal.ii as described in our arxiv preprint https://arxiv.org/abs/1905.00671. We are now working on parallelizing our implementation of MPM.
As the MPM is developed for solid, a particle in MPM may contain a number of tensors (e.g. stains, stresses, and internal variables) as well as velocities, especially when the constitutive model is complex (typical for geomaterials that we deal with). While it is technically possible to write a function that converts a series of tensors into an array of double, it'd be absolutely better if a particle can carry more general types of properties. (If so, I think it can also be used for general nonlinear FE for solid mechanics.) We'd appreciate it if you could think this as a possible feature in the future!
