Construct the mobility matrix from empirical fits.
- Parameters
-
| kernel_name | IB kernel function. |
- Note
- Supported IB kernels are "IB_3", "IB_4" and "IB_6".
- Parameters
-
| mu | Fluid density. |
| rho | Fluid density. |
| dt | The time step size. |
| dx | Cartesian grid spacing. |
| X | Array of IB markers' location. |
| num_nodes | Number of Lagrangian markers. |
| reset_constants | Boolean indicating whether all constants are to be reset if beta (the viscous CFL number) is changed (otherwise will use the previous beta for fitting formula). |
| periodic_correction | Input parameter for incorporating periodic domain correction. Set it to zero if not needed. |
| l_domain | Length of the domain. |
- Note
- This is used only only for 2 dimensional steady stokes.
- Parameters
-
| mm | Pointer to mobility matrix. |
