OpenFOAM lacked a Lagrangian model for electrostatic forces acting on particles based on their diameters.
#### Solution
The present commits furnish a model of this kind, along with essential underlying changes in the 'electricPotential' function object for evaluating the electric field. The coupling is one way (for now).

\endverbatim
In DFM or FSM, a random number set (mostly white noise), and a group
of target statistics (mostly mean flow, Reynolds stress tensor profiles and
lengthscale sets) are fused into a new number set (stochastic timeseries,
yet consisting of the statistics) by a chain of mathematical operations
whose characteristics are designated by the target statistics, so that the
realised statistics of the new sets could match the target.
Random number sets >

DFM or FSM > New stochastic timeseries consisting

Turbulence statistics >
The main difference between DFM and FSM is that the latter replaces the
streamwise convolution summation in DFM by a simpler and a quantitatively
justified equivalent procedure in order to reduce computational costs.
Accordingly, the latter potentially brings resource advantages for
computations involving relatively large lengthscale sets and small
timesteps.
### Resolved bugs (If applicable)
Verified for `serial`, `scotchparallel (4)`, `hierar.parallel (1 2 2)`, `hierar.parallel (1 2 4)`, `serialrestart`, and `parallelrestart` in terms of input Reynolds stress tensor components through `channel395DFSEM` tutorial (onecell domain).
Checked for various possible (commonly encountered) wrong inputs, e.g. arbitrary Reynolds stress tensor components.
### Details of new models (If applicable)
**The model input**:
1. Spatialvariant Reynolds stress symmetric tensor (6components)
2. Spatialvariant mean velocity profile
3. Spatialinvariant (for now) integrallength scale tensor (9components)
**The model output**: Stochastic timeseries involving the statistics of the model input sets.
**The model computation has four subsequent steps:**
1. Generation of randomnumber sets obeying the standard normal probability distribution function
2. Analytical computation of digitalfilter coefficients as a function of integrallength scales in either Gaussian or exponential form
3. Convolution summation between randomnumber sets and digitalfilter coefficients
4. Embedment of Reynolds stress tensor and mean velocity input into the digitalfiltered randomnumber sets via elementwise multiplication and summation
**Fidelity**:
Preliminary statisticallystationary results from a channelheight profile on the patch (onecell domain `channel395DFSEM` case: `hierar.parallel (1 2 4)`):
![stress](/uploads/8dce71846496e6bbc87aca3c78c52bcb/stress.png)
Preliminary **notstatistically developed** (0.6 sec run, ongoing) with **nonoptimal input** results from full `channel395DFSEM` case:
![DG1](/uploads/49f04599abdd34ec9adec65166c8908f/DG1.png)
**Performance**:
Preliminary comparisons with DFSEM suggests that the current model is ~1.8x faster for the `channel395DFSEM` tutorial.
### Risks
1. Model is itself not divergencefree (yet convertible); therefore, should not be preferred for aeroacoustic applications as is. Nonetheless, the mass flow rate correction reduces the inlet pressure fluctuations to the level of Poletto et al.'s DFSEM (quantified and verified by Bercin in comparison to Moser et al'. DNS data for pressure fluctuations and correlations).
2. For now, Taylor's frozen turbulence hypothesis is applied in the streamwise direction.
3. For now, `bilinear interpolation` is not fully functional.
4. Code duplications with DFSEM exist for template funcs.
5. For now, integrallength scale set (9components) is spatialinvariant across patch.
6. Further verification is ongoing through highorder statistics from Moser et al.'s DNS data, e.g. correlations, kinetic energy budget, enstrophy and so on.AdminAdmin
