Convert Panel

Use the Convert panel to exchange data between different solver formats.

Location: Tool page

Data can be exchanged between two card image solvers, or a card image solver and a dictionary solver. The data that is converted from one format to another are component thickness and material properties, Young's Modulus, Poisson's Ratio, and density.

Note: In order for the convert process to work, you must have the HyperMesh template appropriate to your source file.

The other (2.0) solver choice should be used for those solvers that use the dictionary format. All of the other solvers listed are card image solvers.

Thickness Conversion Between Solvers

Conversion Action
Nastran to LS-DYNA It is possible to transfer overall component thickness and individual element nodal thicknesses.
ANSYS to Nastran Thickness of individual components and overall component thickness defined in ANSYS Real constant table can be transferred to individual element nodal thickness for Nastran.
ANSYS to Abaqus Thickness defined in the real constant table of ANSYS is converted to the corresponding component average thickness in Abaqus.
Abaqus to PAM-CRASH 2G Component thickness defined in Abaqus is converted to corresponding component thickness in PAM-CRASH 2G.
Abaqus to ANSYS Component thickness defined in Abaqus is converted to corresponding component thickness in ANSYS.

Panel Options

Option Action

Nastran to DYNA Conversion Tool

Nastran that can be converted to LS-DYNA.

  • PSHELL
  • PSOLID
  • PBAR
  • PBARL
  • PBEAM
  • PBEAML

PSHELL to *Section_Shell Conversion

A *Part card will be associated to the pshell component.
  • A new LS-DYNA property *section_shell will be created and assigned to the *Part card.
  • The original material ID will be assigned to the *Part.
  • The Nastran thickness will be assigned to the T1 *section_shell card.
  • The Nastran NSM value will be assigned to the MAREA LS-DYNA entry.

PSOLID to *Section_Solid Conversion

A *Part card will be associated to the component.
  • A new LS-DYNA property *section_solid will be created and assigned to the corresponding *Part card.
  • The original material ID will be assigned to the *Part.

PBAR to *Section_Beam Conversion

HyperMesh will create different components so that the bar elements using a common Nastran property will be moved into a single component.
  • A *Part card will be associated to this component.
  • A new LS-DYNA property *section_beam with ELFORM 2 will be created and assigned to the *Part card.
  • The original material ID will be assigned to the *Part.
  • The Nastran A field will be mapped to the LS-DYNA AREA entry; the Nastran Inertia I1 I2 and J will be assigned to the corresponding LS-DYNA values Itt Iss and Irr.

PBARL (ROD, TUBE, BAR types) to *Section_Beam Conversion

HyperMesh will create different components so that the bar elements using a common Nastran property will be moved into a single component.
  • A *Part card will be associated to this component.
  • A new LS-DYNA property *section_beam with ELFORM 1 will be created and assigned to the *Part card.
  • The original material ID will be assigned to the *Part.
  • The nonstructural mass, NSM, will be converted between the solvers.
  • For the Pbarl-ROD type, the Nastran entry, DIM1, will be moved to the LS-DYNA Ts1 and Ts2. In the *section_beam card, the CST entry will be set to value 1.
  • For the Pbarl-TUBE type, the Nastran entry DIM1 will be moved to the LS-DYNA Ts1 and Ts2, DIM2 will be assigned to the LS-DYNA entries TT1 and TT2. In the *section_beam card, the CST entry will be set to the value 1.
  • For the Pbarl-BAR type only, the Nastran entry DIM1 will be moved to the LS-DYNA Ts1 and Ts2. In the *section_beam card, the CST entry will be set to value 0.

PBEAM to *Section_Beam Conversion

HyperMesh will create different components so that the beam elements using a common Nastran property will be moved into a single component.
  • A *Part card will be associated to this component.
  • A new LS-DYNA property *section_beam with ELFORM 2 will be created and assigned to the *Part card.
  • The original material ID will be assigned to the *Part.
  • The Nastran A field will be mapped to the LS-DYNA AREA entry; the Nastran Inertia I1 I2 and J will be assigned to the corresponding LS-DYNA values Itt Iss and Irr.
    Note: Note: LS-DYNA does not provide a field to store the I12 value; if the I12 value is available, the conversion will not occur.

PBEAML to *Section_Beam Conversion

The conversion ignores the case of tapered Nastran beam with intermediate cross section.
  • HyperMesh will create different components so that the beam elements using a common Nastran property will be moved into a single component.
  • A *Part card will be associated to the component.
  • A new LS-DYNA property *section_beam with ELFORM 1 will be created and assigned to the *Part card.
  • The original material ID will be assigned to the *Part.
  • The nonstructural mass NSM will be converted between the solvers.
  • For the Pbeaml-ROD type, the Nastran entry DIM1(A) will be moved to the LS-DYNA Ts1, the DIM1(B) will be moved into Ts2. In the *Section_Beam card the CST entry will be set to value 1.
  • For the Pbeaml-TUBE type, the Nastran entry DIM1(A) will be moved to the LS-DYNA Ts1, the DIM1(B) will be moved into Ts2. The Nastran entry DIM2(A) will be moved to the LS-DYNA TT1, the DIM2(B) will be moved into TT2. In the *section_beam card the CST entry will be set to value 1.
  • For the Pbeaml-BAR type, the Nastran entry DIM1(A) will be moved to the LS-DYNA TT1 the DIM1(B) will be moved into TT2. The Nastran entry DIM2(A) will be moved to the LS-DYNA TS1, the DIM2(B) will be moved into TS2. In the *section_beam card the CST entry will be set to value 0.
