## <a name=2016> version 2016 ##
There are several changes concerning the **pre** python module.
Remember that a script is provided in *lmgc90_user/src/addons* attempting to update a single script or all python scripts in a directory tree.
If *lmgc90_user/src/addons* is in your `$PATH` environment variable, run:
```shell
update_gen_2016.py gen_sample.py
```
To update *gen_sample.py* script.
You can replace the script name by a directory to try to update all python scripts in it.
There are cases where the script may fail, here is the list of changes so that you can correct you scripts yourself:
* change of `pre_lmgc` submodule name to `pre` (submodule of `pylmgc90`)
* in `tact_behav` constructor, argument name `type` is replaced by `law`
* in `model` constructor, argument name `type` is replaced by `physics`
* in `material` constructor, argument name`type` is replaced by `materialType`
* in `avatar.addContactors` method, argument name `type` is replaced by `shape`
* in `avatar.rotate` method, argument name `type` is replaced by `description`
* in `avatar.imposeDrivenDof` method, argument name `type` is replaced by `description`
* in `postpro_command` constructor, argument name `type` is replaced by `name`
* in `buildMesh2D` function, argument name `type_mesh` is replaced by `mesh_type`
* in `brick2D.deformableBrick` method, argument name `type` is replaced by `mesh_type`
* in `brick2D.explodedDeformableBrick` method, argument name `type` is replaced by `mesh_type`
* in `avatar` constructor, argument named `type` has been removed
* in `node` constructor, argument named `type` has been removed
* in `element` constructor, argument named `type` is replaced by `elem_dim` and the corresponding value must be the geometrical dimension of the element

*`Reac` and `Raux` become `Ireac` and `Iaux` in the body type definition
* Many functions/accessor in detection modules disappeared. The main way to access to interaction is now through the **handlers**
* Look into the `inter_handler_2/3D` module, the `public` sections list the available functions in each module. The first parameter is the type of interactions which is an integer from the `parameter` module.
## <a name=2016> version 2016 ##
There are several changes concerning the **pre** python module.
Remember that a script is provided in *lmgc90_user/src/addons* attempting to update a single script or all python scripts in a directory tree.
If *lmgc90_user/src/addons* is in your `$PATH` environment variable, run:
```shell
update_gen_2016.py gen_sample.py
```
To update *gen_sample.py* script.
You can replace the script name by a directory to try to update all python scripts in it.
There are cases where the script may fail, here is the list of changes so that you can correct you scripts yourself:
* change of `pre_lmgc` submodule name to `pre` (submodule of `pylmgc90`)
* in `tact_behav` constructor, argument name `type` is replaced by `law`
* in `model` constructor, argument name `type` is replaced by `physics`
* in `material` constructor, argument name`type` is replaced by `materialType`
* in `avatar.addContactors` method, argument name `type` is replaced by `shape`
* in `avatar.rotate` method, argument name `type` is replaced by `description`
* in `avatar.imposeDrivenDof` method, argument name `type` is replaced by `description`
* in `postpro_command` constructor, argument name `type` is replaced by `name`
* in `buildMesh2D` function, argument name `type_mesh` is replaced by `mesh_type`
* in `brick2D.deformableBrick` method, argument name `type` is replaced by `mesh_type`
* in `brick2D.explodedDeformableBrick` method, argument name `type` is replaced by `mesh_type`
* in `avatar` constructor, argument named `type` has been removed
* in `node` constructor, argument named `type` has been removed
* in `element` constructor, argument named `type` is replaced by `elem_dim` and the corresponding value must be the geometrical dimension of the element
