13.1 Data Structured as Entities

• Plotting refers to data files
  

  <name>.in.txt

  <name>.elemout.txt

  <name>.elemout_.txt

  <name>.nodeout.txt

  <name>.nodeout_.txt

  <name>.pkl

  
  and option files
  

  <name>.opt.txt

  <name>.plt.txt

• Plotting may be performed automatically following a computation or standalone using data of a previously finished computation.

  • In case of .EXE-Version, see Section 8, the corresponding procedures are requested with the prompt window dialogue.

  • In case of using source codes the corresponding procedures are ruled within the module ConFemData.py – by definition of Name, Plot –, or in the module ConFemPost.py by definition of Name in the __main__-section., see Section 2.

• Plotting works with entities

  • An entity is assigned to an instant in time, according to data output statements given in Section 12.

• Node entities

  • All nodes of a model form an entity with respect to plotting. A number of corresponding node entities may arise due to a number of instants in time.

• Element entities

  • All elements belonging to a particular element set – generally of the same element type, see Section 10.3 – form an entity with respect to plotting. A number of corresponding element entities may arise due to a number of instants in time.

  • Three types of element entities are basically distinguished:

    • line element entities are related to
      S1D2,T1D2,B21,B21E,B23,B23E

      • Line element entities have sub-entities considering quantities like normal forces, bending moments, distinguished strains and stresses and more.

    • 2D element entities are related to
      T2D2,T2D3,T2D2E,T2D3E,CPS4,CPE4,CPS3,CPE3,SB3

      • 2D element entities generally do not have sub-entities.

      • Exception is SB3 with sub-entities bending moments and shear forces

    • 3D element entities are related to
      SH4,SH3

      • 3D element entities have sub-entities considering quantities like components of bendig moments, normal/membrane forces and shear forces.
