   **input_abaqus**  *switch*


Set *switch* to *-yes* for reading the *Abaqus* input file *abaqus.inp*. *Tochnog* will use it to generate a *Tochnog* input file *tochnog_abaqus.dat*. This can typically be done by making an input file like:

.. code-block::

   ...
   echo -yes
   number_of_space_dimensions 3
   materi_velocity
   materi_stress
   end_initia
   input_abaqus -yes
   input_abaqus_mesh -no
   input_abaqus_continue -yes
   ...
   include tochnog_abaqus.dat
   ...
   ( other data , you can use the abaqus sets of tochnog_abaqus.dat )
   ...
   end_data

You need to initialise the fields like :ref:`materi_velocity`, :ref:`materi_stress`, etc that you will actually use later in the calculation. Only a limited set of data is transferred from the *Abaqus* input file to the *Tochnog* input file; You need to check if the *Tochnog* input file is like You want. *Abaqus* element sets and node sets are evaluated and can be used in the *Tochnog* calculation.

*Abaqus* is a registered trademark or trademark of Dassault Systèmes. *Abaqus* input files can be generated by many programs, among which *Mecway* is relatively affordable, see `mecway.com <https://mecway.com/>`_.

input_abaqus_continue
---------------------

.. admonition:: Syntax:
   :class: tip

   **input_abaqus_continue**  *switch*

If *switch* is set to *-yes* then after *tochnog_abaqus.dat* is generated the remainder of the input le read and the calculation continues. If switch is set to *-no* then after *tochnog_abaqus.dat* is generated the remainder of the input file will not be read and the calculation aborts. The :ref:`input_abaqus_continue` record should always be present as last record of the **input_abaqus_\*** records.


------------------
input_abaqus_group
------------------

.. admonition:: Syntax:
   :class: tip

   **input_abaqus_group**  *switch*

If *switch* is set to *-yes* then also **group_\*** is written to *tochnog_abaqus.dat*. If *switch* is set to *-no* then no **group_\*** is written to *tochnog_abaqus.dat*. So you can set *switch* to *-no* in case you want to provide the **group_\*** yourself, and don't want it to be taken from the *abaqus.inp*. By default, if :ref:`input_abaqus_group` is not specied, the *switch* is set to *-yes*.


-----------------
input_abaqus_mesh
-----------------

.. admonition:: Syntax:
   :class: tip

   **input_abaqus_mesh**  *switch*

If *switch* is set to *-no* then only mesh data is written to *tochnog_abaqus.dat*; so timestep information and post processing prints are not written. This record should be placed before the :ref:`input_abaqus_continue` record.

.. note::

   By default the switch is set to *-no*.
