◆ cs_lagr_sde_attr()
Integration of a stochastic differential equation (SDE) for a user particle variable (attribute).
When there is interaction with a boundary face, the integration degenerates to order 1 (even if the 2nd order scheme is active).
- Parameters
-
[in] | attr | attribute/variable |
[in] | tcarac | variable characteristic time |
autotoc_md52
- Parameters
-
[in] | pip | right-hand side associated with SDE |
