The current input data consist of one archive with .mdpa extension. The input file is free format and the reading is not depend to the spaces, tabs, endlines etc.

This format contains all ModelPart's data in a minimalistic block form and consists of 8 blocks of data in following form:

Begin ModelPartData
  //  VARIABLE_NAME value
End ModelPartData

Begin Table table_id variable1 variable2 
  // table_x table_y
End Table
 
Begin Properties  properties_id 
  //  VARIABLE_NAME value
End Properties
 
Begin Nodes
  // id	  X	Y	Z
End Nodes
 
Begin Elements element_name
  // id prop_id	 n1	n2	n3	...
End Elements
 
Begin Conditions condition_name 
  // id prop_id	 n1	n2	n3	...
End Conditions
 
Begin NodalData VARIABLE_NAME
  //  id is_fixed value
End NodalData
 
Begin ElementalData VARIABLE_NAME
  //  id value
End ElementalData
 
Begin ConditionalData VARIABLE_NAME
  //  id value
End ConditionalData 
 
Begin Mesh mesh_id   // mesh_id cannot be zero!
  Begin MeshNodes
    // node_id
  End MeshNodes
 
  Begin MeshElements
    // element_id
  End MeshElements
 
  Begin MeshConditions
    // condition_id
  End MeshConditions
End Mesh

Begin SubModelPart SubModelPartName
  Begin SubModelPartTables
    // Table_id
  End SubModelPartTables

  Begin SubModelPartNodes
    // node_id
  End SubModelPartNodes

  Begin SubModelPartElements
    // element_id
  End SubModelPartElements

  Begin SubModelPartConditions
    // condition_id
  End SubModelPartConditions

  Begin SubModelPart SubModelPartName // Note that this would be a sub sub modelpart
    Begin SubModelPartTables
      // Table_id
    End SubModelPartTables
  
    Begin SubModelPartNodes
      // node_id
    End SubModelPartNodes

    Begin SubModelPartElements
      // element_id
    End SubModelPartElements

    Begin SubModelPartConditions
      // condition_id
    End SubModelPartConditions
  End SubModelPart
End SubModelPart

Each block starts with a Begin statement following by the block name and ends with the End statement again following by the block name. Some block may have some additional parameter like id or variable in their definitions.

An example is presented in the following lines:

Begin ModelPartData
  //  VARIABLE_NAME value
  AMBIENT_TEMPERATURE 250.00
End ModelPartData
 
Begin Table 1 TEMPERATURE VISCOSITY
  200. 2e-6
  300. 3e-6
  400. 4e-6
End Table

Begin Properties 1
  DENSITY 3.4E-5  //scalar
  THICKNESS 19.5
  VOLUME_ACCELERATION [3] (0.00,0.00,9.8) //vector
  LOCAL_INERTIA [3,3] ((0, 0.27,0.27),(0.087,0,0.27),(0.075,0.23,0)) // matrix

  Begin Table TEMPERATURE VISCOSITY
    200. 2e-6
    300. 3e-6
    400. 4e-6
  End Table
