Nastran that can be converted to LS-DYNA.
- PSHELL
- PSOLID
- PBAR
- PBARL
- PBEAM
- PBEAML
PSHELL to *Section_Shell Conversion
- 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 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
- 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
- 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
- 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: 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
- HyperWorks 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.
